Congratulations to the ACS3 Team on the Successful Unfurling of Solar Sail

Ames and Langley just added another light to the night sky. Congratulations to the Advanced Composite Solar Sail System (ACS3) team on the successful test of our next-generation solar sail technology that will allow future small spacecraft to “sail on sunlight” as they explore the cosmos. On Aug. 29, the team saw the first images captured by the CubeSat cameras as the mission accomplished its primary objective – successfully deploying the reflective polymer solar sail and its four composite booms in space. We are eager to share high-resolution images from the spacecraft in the coming weeks.

As the team celebrates achieving this milestone and the exciting possibilities for future small spacecraft missions, it’s a bittersweet victory. As many of you know, the mission’s lead systems engineer, Alan Rhodes, passed away unexpectedly in June. He devoted more than three years to the mission and watched with enthusiasm as the CubeSat launched on April 23. He is in our thoughts as the mission celebrates this latest milestone. 

After sunset, the best opportunities to see the CubeSat’s sail that spans 33 x 33 feet or half a tennis court will be in the northern skies. Stay tuned to NASA.gov and @NASAAmes on social media for updates on how to see the spacecraft passing over your area. Look for details in an upcoming centerwide with instructions on how to use the NASA App to help you narrow your search for the most accurate viewing opportunities.

This mission is another shining example of the inspiration, talent, and innovation that drives the work that we do to develop forward-thinking technologies. Our efforts are impactful and continue to create new possibilities for robotic spaceflight. We can’t wait to see what’s next for the Advanced Composite Solar Sail System.

NASA Celebrates Ames’ Legacy of Research on National Aviation Day

by Tara Friesen

NASA works every day to improve air travel – and has been doing so since its creation decades ago. On National Aviation Day, Aug. 19, NASA and all fans of aviation got the chance to celebrate the innovative research and development the agency has produced to improve capability and safety in flight.

Early research at NASA’s Ames Research Center in California’s Silicon Valley — then known as NACA Ames Aeronautical Laboratory – included ground tests of “hot wing” anti-icing systems on a Lockheed 12A aircraft.

NASA’s Ames Research Center in California’s Silicon Valley has a historic legacy in aeronautics research. When the center was founded in 1939 by the National Advisory Committee for Aeronautics (NACA), its early research included working to reduce icing on aircraft wings.

When ice coats the wings of an airplane, it reduces lift and increases drag, which can cause the aircraft to lose altitude and control. Ames researchers developed different approaches to solve the icing challenge, including a “hot wing” thermal anti-icing system. The system worked by running hot engine exhaust along the leading edges of aircraft wings, warming them and preventing ice buildup. Ames researchers modified aircraft and tested them before traveling to Minnesota, where they were flown in icy conditions.

Today, many turbine-powered aircraft, like passenger jets, use “bleed air” anti-icing systems, which warm the leading edges of aircraft wings using compressed air from their engines. These systems are built upon the early research and testing done at Ames.

The legacy of aviation innovation continues at Ames, through aeroscience research like wind tunnel testing, air traffic management, and advanced aircraft systems.

Ames’ WIN, WiO and the USAF Host Inspiring Women’s Equality Day Event

In 1973, Congress designated August 26 as Women’s Equality Day to commemorate the 1920 certification of the 19th Amendment to the Constitution, granting women the right to vote. Since then, the observance has grown to include focusing attention on women’s continued efforts toward gaining full equality. Voting is one of the primary ways we participate in the political process, express our opinions, and help shape the goals and values of our nation. Since 1973, we have celebrated Women’s Equality Day on Aug. 26 to commemorate the certification of the 19th Amendment in 1920, which granted women the right to vote. We honor the efforts of the suffragists who fought tirelessly for equality throughout the early 1900s and the work that continued after certification to ensure all women were able to exercise that right.

The WIN/WiO panel
The WIN/WiO panel included the following speakers, left to right: Dr. Meghan Saephan, computer engineer in the Intelligent Systems Division and chair of the Women’s Influence Network Employee Resource Group; Shaina Sethna, safety engineer in the Plant Engineering Branch, member of the Women in Operations group and Women’s Influence Network, and the Special Emphasis Program manager for Federal Women at Ames; Erin Cook, deputy center director of Center Operations and colonel in the Air Force Reserves, where she serves as the Individual Mobilization Augmentee to the vice commander Air Logics Complex, in Oklahoma City, and the Ames Women in Operations group executive sponsor; and Bee Davis, a senior infrastructure engineer at Johnson Space Center in the Flight Operations Directorate, and member of the Women’s Influence Network Employee Resource Group. The moderator, far right, was Airman First Class Nicholas Mangrum.

At the time of its founding in 1958, NASA was a male-dominated workforce. By the 1960s, women were making significant contributions to the Apollo mission. Today, the trend continues to head in the right direction. Five of NASA’s 10 centers have women directors in center leadership and women are engaged in every facet of science, discovery, and exploration.

Ames’ Women’s Influence Network (WIN), Women in Operations (WiO), and the US Air Force National Guard hosted an inspiring Women’s Equality Day event on Aug. 26 at the RQW Airmen Resiliency Center in Mountain View.  The Ames event included a panel featuring women from WIN and WiO, as well as presentations from NASA leaders, local elected officials, and other government agencies.  Mayor Yan Zhao from the City of Saratoga attended.  Mayor Pat Showalter from the City of Mountain View provided opening remarks, along with Deputy Center Director Dr. Dave Korsmeyer.  

A presentation by the 129th Rescue Wing, which consists of the entire Air National Guard unit at Moffett Field. This portion of the program highlighted airmen in the 129thRescue Wing that had gone above and beyond. A second panel discussion was then held by the San Francisco Federal Bureau of Investigation.

NASA also hosted an agencywide event on Aug. 26, featuring Deputy Administrator Pam Melroy, Armstrong Flight Research Center’s Deputy Center Director Laurie Grindle, and NASA Historian Jennifer Ross-Nazzal.

Women’s Equality Day provides an opportunity to underscore the agency’s commitment to providing an inclusive and equitable workplace today and ensuring a welcoming future for the next generation of employees. It is not only the right thing to do; it is essential to NASA’s success.

NASA Seeks Input on Safety for Future Commercial Drone Operations

by Hillary Smith

NASA recently gathered representatives from the Federal Aviation Administration (FAA), police and fire departments, and commercial industry to figure out how to take an important step for public safety drones: allowing them to fly past where their operators can see them. 

Currently, most drone operations are limited to areas known as “visual line of sight” for safety purposes. However, engineers and researchers are developing the infrastructure to allow drones to operate beyond this point. As the FAA works to authorize these types of flights, NASA is helping ensure these operations are safe and efficient.

This work from NASA and the FAA could have significant commercial applications – including drone deliveries – but at their June meeting, the agencies were focused on public safety drones used for search-and-rescue, accident scene reconstruction, and situational awareness during fires and other emergencies. Researchers need to figure out how drones on public safety missions can operate safely beyond visual line of sight – and do so in airspace shared with drones on commercial missions. 

Hosted by NASA’s Ames Research Center in California’s Silicon Valley, the meeting took place in Arlington, Texas City Hall. Attendees included members of the FAA, the Department of Homeland Security, the Texas Department of Public Safety, the Arlington local police and fire departments, and representatives of the Dallas-Fort Worth International Airport. The group’s discussion included the special considerations needed for public safety drone operations beyond visual line of sight. And they identified at least one significant challenge: how to ensure that public safety drones have priority when operating in the same airspace with commercial drones. 

NASA researchers provided feedback from this session to the FAA, commercial drone operators, and service providers. Input from the public safety meeting will support the FAA’s evaluation of commercial drone flights beyond visual line of sight, which the agency is currently conducting in the Dallas-Fort Worth area. Data from these operations will inform FAA rulemaking. 

NASA’s work is led by its Uncrewed Aircraft Systems Traffic Management System Beyond Visual Line of Sight effort, which falls under the Air Traffic Management Exploration project. This subproject directly supports NASA’s Advanced Air Mobility mission. Advanced Air Mobility aims to transform our communities by bringing the movement of people and goods off the ground, on demand, and into the sky.  

New Zealand Prime Minister Tours Ames, Celebrates Partnership

On July 12, Ames welcomed the Prime Minister of New Zealand, Christopher Luxon. New Zealand was a pivotal partner in crafting the Artemis Accords and is a longstanding partner with NASA in commercial space and Earth science.

At Ames, the prime minister was hosted in the Advanced Supercomputing Facility where he was briefed on Ames’ core competences and learned about NASA’s partnership with Rocket Lab to launch missions from New Zealand’s coast including the Advanced Composite Solar Sail,Starling, and CAPSTONE.

In addition, Ames experts briefed the prime minister on NASA’s and New Zealand’s collaborative efforts to study Earth’s interconnected systems. He also learned about SOFIA’s enduring connection to New Zealand, which hosted the aircraft seven times to observe objects visible in the southern hemisphere.

Before leaving the center, the prime minister visited the Pleiades and Cabeus supercomputers and examined the capabilities of the facility’s upgraded hyperwall, which brings numerical data to life with over a billion pixels across 128 screens.

Ames leadership spoke with the prime minister about a partnership between NASA’s Indigenous Peoples Initiative, the Society for Māori Astronomy Research and Traditions, and members of the Māori Working Group in Aerospace. This partnership will support the need for Māori-led initiatives to monitor environmental and ecological impacts in their communities and add diverse voices to Earth observations and research.

It is a privilege to welcome our international partners to Ames and share our wealth of knowledge and technology. Collaboration is critical to NASA’s mission, particularly as we go back to the Moon and beyond, together. We value our continued partnership with New Zealand and their role in Earth science and the evolving commercial space industry.

NASA’s Upgraded Hyperwall Offers Improved Data Visualization

by Tara Friesen

In May, the NASA Advanced Supercomputing (NAS) facility, located at Ames Research Center, celebrated the newest generation of its hyperwall system, a wall of LCD screens that display supercomputer-scale visualizations of the very large datasets produced by NASA supercomputers and instruments.

The upgrade is the fourth generation of hyperwall clusters at NAS. The LCD panels provide four times the resolution of the previous system, now spanning across a 300-square foot display with over a billion pixels. The hyperwall is one of the largest and most powerful visualization systems in the world. 

Systems like the NAS hyperwall can help researchers visualize their data at large scale, across different viewpoints or using different parameters for new ways of analysis. The improved resolution of the new system will help researchers “zoom in” with greater detail. 

The hyperwall is just one way researchers can utilize NASA’s high-end computing technology to better understand their data. The NAS facility offers world-class supercomputing resources and services customized to meet the needs of about 1,500 users from NASA centers, academia and industry.

NASA Cloud-Based Platform Could Help Streamline, Improve Air Traffic

by John Gould

Just like your smartphone navigation app can instantly analyze information from many sources to suggest the best route to follow, a NASA-developed resource is now making data available to help the aviation industry do the same thing.

To assist air traffic managers in keeping airplanes moving efficiently through the skies, information about weather, potential delays, and more is being gathered and processed to support decision making tools for a variety of aviation applications.

Appropriately named the Digital Information Platform (DIP), this living database hosts key data gathered by flight participants such as airlines or drone operators. It will help power additional tools that, among other benefits, can save you travel time.

“Through DIP we’re also demonstrating how to deliver digital services for aviation users via a modern cloud-based, service-oriented architecture,” said Swati Saxena, DIP project manager at NASA’s Ames Research Center in California.

The intent is not to compete with others. Instead, the hope is that industry will see DIP as a reference they can use in developing and implementing their own platforms and digital services.

“Ultimately, the aviation industry – the Federal Aviation Administration, commercial airlines, flight operators, and even the flying public – will benefit from what we develop,” Saxena said.

The platform and digital services have even more benefits than just saving some time on a journey.

For example, NASA recently collaborated with airlines to demonstrate a traffic management tool that improved traffic flow at select airports, saving thousands of pounds of jet fuel and significantly reducing carbon emissions.

Now, much of the data gathered in collaboration with airlines and integrated on the platform is publicly available. Users who qualify can create a guest account and access DIP data at a new website created by the project.

It’s all part of NASA’s vision for 21st century aviation involving revolutionary next-generation future airspace and safety tools.

Managing Future Air Traffic

During the 2030s and beyond, the skies above the United States are expected to become much busier.

Facing this rising demand, the current National Airspace System – the network of U.S. aviation infrastructure including airports, air navigation facilities, and communications – will be challenged to keep up. DIP represents a key piece of solving that challenge.

NASA’s vision for future airspace and safety involves new technology to create a highly automated, safe, and scalable environment.

What this vision looks like is a flight environment where many types of vehicles and their pilots, as well as air traffic managers, use state-of-the-art automated tools and systems that provide highly detailed and curated information.

These tools leverage new capabilities like machine learning and artificial intelligence to streamline efficiency and handle the increase in traffic expected in the coming decades.

Digital Services Ecosystem in Action

To begin implementing this new vision, our aeronautical innovators are evaluating their platform, DIP, and services at several airports in Texas. This initial stage is a building block for larger such demonstrations in the future.

“These digital services are being used in the live operational environment by our airline partners to improve efficiency of the current airspace operations,” Saxena said. “The tools are currently in use in the Dallas/Fort Worth area and will be deployed in the Houston airspace in 2025.”

The results from these digital tools are already making a difference.

Proven Air Traffic Results

During 2022, a NASA machine learning-based tool named Collaborative Digital Departure Rerouting, designed to improve the flow of air traffic and prevent flight delays, saved more than 24,000 lbs. (10,886 kg.) of fuel by streamlining air traffic in the Dallas area.

If such tools were used across the entire country, the improvements made in efficiency, safety, and sustainability would make a notable difference to the flying public and industry.

“Continued agreements with airlines and the aviation industry led to the creation and expansion of this partnership ecosystem,” Saxena said. “There have been benefits across the board.”

DIP was developed under NASA’s Airspace Operations and Safety Program.

Cagle received the award during Black Space Week, following her participation on a panel with fellow astronauts Victor Glover, Jessica Watkins, Leland Melvin, and Joan Higginbotham at the National Museum of African American History and Culture. The panel examined the past, present, and future of space exploration.

At the event, Cagle shared her insight upon returning from a sailing research trip studying the geoscience and thermal chemical profiles of the oceans in anticipation of planetary soil sampling opportunities for future lunar and Mars missions. As NASA prepares to send humans back to the Moon and on to Mars, we need to consider, “The way the planet speaks, the way the soil speaks, the way the ocean can let us know when its coasts are under strain, and how that can be really disruptive to our planet and our lives… And I began to realize that the Earth is alive; it breathes. And I really want to use some of the discoveries I’ve made over my years as a medical doctor and overlay them on the face of the Earth, and then take that perspective to look back from the lens of space to see if we can all come together, work together to regenerate, thrive, and sustain ourselves both here on the planet and off.”

This most recent award joins many others that recognize Cagle’s excellence, including the National Defense Service Medal, Air Force Achievement Medal, United States Air Force Air Staff Exceptional Physician Commendation and National Technical Association Distinguished Scientist Award. A senior flight surgeon and a contributor to the study of astronaut health, Cagle is a valued colleague at Ames and an inspiration to the next generation of medical doctors, scientists, and space explorers.

NASA Public Engagement Specialist Jonas Dino Loves to Inspire Kids with STEM

by Gianine Figliozi

Careers at NASA were not on his radar growing up. But Jonas Dino, public engagement specialist at NASA’s Ames Research Center in California’s Silicon Valley, ended up with his perfect job that involves connecting people with NASA.

Jonas Dino speaks to students at the Cezar Chavez Middle School in Union City, California.

One of the best parts of his job is to learn first-hand about NASA’s cutting-edge research and translate these concepts to the next generation.

“I’m excited about what NASA does and where we are going,” said Dino, “As an extrovert, I love interacting with the public, especially little kids.”

When speaking to younger children, Dino often kneels, to get to their level. With the future of aeronautics and space exploration in mind, he has a message for them: ‘NASA needs you.’ 

“They love space and think it is very cool, but many don’t think they could ever work at NASA,” said Dino. “I want to help them see: anything is possible.”

A path to NASA he didn’t know existed

A first-generation immigrant from the Philippines, Dino’s academic start focused on studying life sciences. 

“As a Filipino, you’re encouraged to go into the medical field as a career,” said Dino. 

After joining the Marine Corps, Reserve, he returned home to study biology at San Jose State University (SJSU). After doing poorly at organic chemistry, he took his next “logical” step and switched his major to nursing. After working in the field, he realized that was not for him either. Luckily, he had been taking psychology classes, following his interests, and could graduate with a psychology degree by only taking two more classes.

After three changes in major and just getting ready to graduate, Dino was hit by a car. His injury and subsequent recovery gave him time to evaluate what he wanted to do with his life. 

“I was pretty good at talking to people and teaching,” said Dino. “Maybe I could do that as a job?”  

Dino started his teaching career at James Logan – the same high school he graduated from in 1985. He eventually ran for and was elected as a trustee for the New Haven Unified School District in the San Francisco Bay Area. Unfortunately, to take that seat, he could not be a teacher in the district – a conflict of interest. Suddenly needing a job, he found the internship book at SJSU where he was getting his master’s degree. Soon, he was evaluating opportunities: a high-tech company or NASA?

“It was during the dotcom boom and my family strongly encouraged me to take the high-tech internship,” said Dino. “I took the internship at NASA Ames and have never regretted my decision.”

Working as a communicator, Dino has covered the gamut of NASA projects from aeronautics to space missions, including a lunar mission, LCROSS, that helped confirm the presence of water on the Moon. 

His favorite part of his job is STEM engagement. 

“There is nothing like seeing a kid’s eyes get larger, or that proverbial light-bulb-turn-on-above-their-heads when you teach them something new,” said Dino. “When you see kids are hungry for science, you need to feed it.”

He did serve his community on the school board for four terms – 16 years. Now, he serves as an advocate for the NASA Ames workforce as president of the Ames Federal Employees Union.

“NASA is a great place to work, it has been a blast, for nearly 24 years.”

Nudging an asteroid

A little push in the right direction, even incidental, can have a huge effect on your trajectory – and thus where you end up – if it happens early on. This is true both for rogue rocks, on the loose in the solar system, and for people too.

“When I was a kid, I took apart everything because I wanted to know what’s inside and how everything worked,” said Dino. “Looking back, I should have been an engineer.” 

“I have two children, a son and a daughter,” said Dino. “I’m encouraging my daughter to go into STEM; we need more young women in STEM careers but too many girls are pushed away from this choice by the time they are in middle school. I also want to encourage Filipino kids to make their own career choices and maybe even to come work for NASA.”

To help pursue these goals, Dino started a memorial scholarship in honor of his father for Filipino students going into STEM fields. He handed out the inaugural scholarship for this last May. 

Jonas Dino quote

NASA never stops for Dino. Whether at work or on his free time, he’s always talking about NASA. While dishing out samples of his Filipino adobo recipe during a recent adobo-cooking contest – according to Dino, every Filipino family has their own recipe for this dish – he also handed out NASA knowledge. He won second place.

Surfing NASA’s Internet of Animals: Satellites Study Ocean Wildlife

Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the newcomer. They zoom close and veer away at the last minute, as Gilmour slowly makes her way toward the kaleidoscope of green sprouting from the island ahead.

Gilmour, a scientist at NASA’s Ames Research Center in California’s Silicon Valley, conducts marine ecology and conservation studies using data collected by the U.S. Geological Survey (USGS) from animals equipped with wildlife tags. Palmyra Atoll, a United States marine protected area, provides the perfect venue for this work.

A collection of roughly 50 small islands in the tropical heart of the Pacific Ocean, the atoll is bursting with life of all kinds, from the reef sharks and manta rays circling the shoreline to the coconut crabs climbing palm branches and the thousands of seabirds swooping overhead. By analyzing the movements of dolphins, tuna, and other creatures, Gilmour and her collaborators can help assess whether the boundaries of the marine protected area surrounding the atoll actually protect the species they intend to, or if its limits need to shift.

Launched in 2020 by The Nature Conservancy and its partners – USGS, NOAA (National Oceanic and Atmospheric Administration), and several universities – the project team deployed wildlife tags at Palmyra in 2022, when Gilmour was a scientist with USGS.

Now with NASA, she is leveraging the data for a study under the agency’s Internet of Animals project. By combining information transmitted from wildlife tags with information about the planet collected by satellites – such as NASA’s Aqua, NOAA’s GOES (Geostationary Operational Environmental Satellite) satellites, and the U.S.-European Jason-3 – scientists can work with partners to draw conclusions that inform ecological management.

“Internet of Animals is more than just an individual collection of movements or individual studies; it’s a way to understand the Earth at large,” said Ryan Pavlick, then Internet of Animals project scientist at NASA’s Jet Propulsion Laboratory in Southern California, during the project’s kickoff event.

The Internet of Animals at Palmyra

“Our work at Palmyra was remarkably comprehensive,” said Gilmour. “We tracked the movements of eight species at once, plus their environmental conditions, and we integrated climate projections to understand how their habitat may change. Where studies may typically track two or three types of birds, we added fish and marine mammals, plus air and water column data, for a 3D picture of the marine protected area.”

Now, the NASA team has put that data into a species distribution model, which combines the wildlife tracking information with environmental data from satellites, including sea surface temperature, chlorophyll concentration, and ocean current speed. The model can help researchers understand how animal populations use their habitats and how that might shift as the climate changes.

Preliminary results from Internet of Animals team show that the animals tracked are moving beyond the confines of the Palmyra marine protected area. The model identified suitable habitats both in and around the protected zone – now and under predicted climate change scenarios – other researchers and decisionmakers can utilize that knowledge to inform marine policy and conservation.

Following a 2023 presidential memorandum, NOAA began studying and gathering input on whether to expand the protected areas around Palmyra and other parts of the Pacific Remote Islands Marine National Monument. Analysis from NASA’s Internet of Animals could inform that and similar decisions, such as whether to create protected “corridors” in the ocean to allow for seasonal migrations of wildlife. The findings and models from the team’s habitat analysis at Palmyra also could help inform conservation at similar latitudes across the planet.

Beyond the Sea: Other Internet of Animals Studies

Research at Palmyra Atoll is just one example of work by Internet of Animals scientists.

Claire Teitelbaum, a researcher with the Bay Area Environmental Research Institute based at NASA Ames, studies avian flu in wild waterfowl, investigating how their movement may contribute to transmission of the virus to poultry and other domestic livestock.

Teams at Ames and JPL are also working with USGS to create next-generation wildlife tags and sensors. Low-power radar tags in development at JPL would be lightweight enough to track small birds. Ames researchers plan to develop long-range radio tags capable of maximizing coverage and transmission of data from high-flying birds. This could help researchers take measurements in hard-to-reach layers of the atmosphere.

With the technology brought together by the Internet of Animals, even wildlife can take an active role in the study of Earth’s interacting systems, helping human experts learn more about our planet and how best to confront the challenges facing the natural world.

In Memoriam…

NASA Science Instrument Development Manager Alan Rhodes Passes Away

Alan Rhodes passed away on June 27 at his home in St. Louis, Missouri. Alan came to Ames in 2016 when he joined the Stratospheric Observatory for Infrared Astronomy (SOFIA) program, our now retired flying telescope, and managed science instrument development efforts through 2020. He then joined the Advanced Composite Solar Sail System (ACS3) mission, a CubeSat that uses solar sails powered by the Sun, as the mission’s lead systems engineer.

Alan served as a project manager for most of his career. After graduating college, he worked for the Naval Undersea Warfare Center as an acquisition management specialist from 2001-2003. From 2003-2005, he was a foreign comparative test project manager and from 2005-2006, he was a senior analyst in integrated warfare systems for Stanley Associates. His first position with NASA was as a test director and project manager at Johnson Space Center in Houston from 2006-2011. Between 2012-2016, Alan worked as project manager for the US Corps of Engineers, the Small Business Innovation Research (SBIR) for the National Oceanographic and Atmospheric Administration (NOAA) and Bonneville Power Administration. He rejoined NASA in 2016.

Anyone who had the privilege of working with Alan can vouch for his enthusiasm. He believed in NASA’s mission and went out of his way to let colleagues know that he valued and appreciated them. He was genuinely excited to be involved in furthering our knowledge of space. He said at the time of the ACS3 launch in April 2024, “The hope is that the new technologies verified on this spacecraft will inspire others to use them in ways we haven’t even considered.”

Although Alan witnessed the launch of the CubeSat and watched it meet its milestones, unfortunately, he did not get to see the final test. In the upcoming weeks, we can all watch in anticipation as ACS3 unfurls its sails in space and tests the novel lightweight flexible composite booms. Cameras mounted on the spacecraft will capture this spectacular feat to share with the world. 

Alan made a big impact in a relatively short time and his untimely death is a reminder that no one knows how much time we have on Earth. A flag ceremony was held at Ames to honor Alan on July 31, in front of the N200 flagpoles. 

Alan appreciated the importance of sharing NASA’s story so others can learn and build upon it. It’s important for us to never take one day for granted. Our work at NASA makes a difference to people today and the agency’s impact will benefit generations to come.

Former Ames Deputy Director, Aeronautical Engineer Vic Peterson Passes

Victor (Vic) Lowell Peterson, age 90, passed away at his home in Los Altos, California on July 10. Vic was active and engaged up until the very end. He learned of his extensive cancers days before his death. He lived an amazing, full, and rich life.

Vic was born June 11, 1934 in Saskatoon, Saskatchewan, Canada to Edwin and Ruth (McKeeby) Peterson. His father served as headmaster of several deaf and blind schools through Canada and Montana before the family moved to Portland, Oregon. Vic was the last surviving member of his family as his older and younger brothers predeceased him.

vicpeterson
Victor L. Peterson, former Ames deputy director and aeronautical engineer.

Vic was an avid midget and IndyCar race fan from the age of 12. He met a midget car owner on his paper route and was soon working as a pit crew member—the beginning of his love for engineering. They always referred to him as their son and introduced him to legendary race car drivers.

Throughout high school, Vic worked at the Davidson Bakery where the owner wanted to send him to baking school with the intent of taking over the business. He played trombone in the high school band, with a subset of the band playing dance gigs.

His love, however, was aeronautical engineering. He attended Oregon State University (1952 -1956) where he was part of the inaugural Aeronautical Engineering class. Vic was a member of Acacia Fraternity while at Oregon State. He earned his B.S. Aeronautical Engineering and was commissioned 2nd Lt. USAF upon graduation in 1956. He was honorably discharged from the USAF with rank of Captain after, as he put it, only having a desk job. Vic also earned an M.S. Aeronautics and Astronautics Sciences from Stanford University and an M.S. Management as an Alfred P. Sloan Fellow from Massachusetts Institute of Technology. He authored more than 50 technical publications and received numerous citations and awards, including the Presidential Rank Award of Distinguished Executive at the White House from President George H. W. Bush.

Vic was recruited to work at the National Advisory Committee for Aeronautics (NACA), Ames Aeronautical Laboratory, at Moffett Field, right out of college. That was the beginning of his long and illustrious career at NASA. He began as an aeronautical research intern, was soon promoted to aeronautical research engineer, and aerospace research scientist before moving into managerial roles: assistant chief, Hypersonic Aerodynamics branch; chief, Aerodynamics branch; Chief, Thermo and Gas Dynamics division; director of Astronautics; director of Astrophysics; and finally deputy director. Vic retired in 1992. He always spoke fondly of the people and his time at Ames Research Center. He often remarked that he was fortunate to have his dream job at the place he most wanted to work for his entire career.

Vic met Jacquie Hubbard at Oregon State. They married December 21, 1955. He is survived by his wife, Jacquie, of 68 years, his daughters Linda Fouquet and Janet Peterson, and son-in-law Sam Fouquet. His son, Victor Craig Peterson died in 2012. He had five grandchildren and four great-grandchildren. His family brought immense joy to him.

He designed and built the addition of their Los Altos home and completed an elaborate landscaping project after retirement. He enjoyed his home, gardening, investing, and staying connected with his fellow NASA retirees. 

When asked what he did at work, Vic inevitably replied, “My day was a day like all days, filled with the events that make history.” And indeed it was. Vic Peterson was brilliant, committed, humble, and loving. 

A Service of Remembrance and Thanksgiving Celebrating the Life of Victor L. Peterson will be held on Oct. 8, 2024, at Noon at Sunnyvale United Methodist Church, located at 535 Old San Francisco Road, Sunnyvale, California, 94086.

Former Chief Counsel at Ames Jack Glazer Passes

Jack H. Glazer, S.J.D., died on May 24, at his home, a historical landmark on Nob Hill conveyed as his gift to the University of California, San Francisco (UCSF). Predeceasing him on August 30, 2001, was his beloved and adored wife, Zelda d’Angleterre Glazer, whose funeral urn was interred with him at Home of Peace Cemetery in Colma, California. Additionally, her name and accomplishments have been memorialized by Jack both in the creation of a Chair on Brain Tumor Research established at UCSF and in the identity of the historical property transferred by gift to that institution on his wife’s name.

Distinguished career paths both in the U.S. Navy as a combat veteran and in his civilian pursuits as a lawyer were Jack’s lot in life. As to the Navy in 1945, at age 17, he left the South Bronx to enlist as an apprentice seaman, ultimately remaining through the years in the Ready Reserve and retiring from the Navy in 1988, after obtaining the rank of captain. Turning to his experiences as a member of the California and District of Columbia Bars, his more inviting assignments included service in Geneva Switzerland as legal counsel to the International Telecommunication Union, a United Nations specialized agency involved in the elaboration of the first multilateral treaties applicable to the legal regime of outer space.
After returning to the United States, Jack embarked in 1965, upon an enviable legal career spanning some 23 years as Chief Counsel at Ames Research Center, an assignment capped by an award of NASA’s Exceptional Service Medal. On his academic side in the law, he was armed with degrees ranging from the baccalaureate to the doctorate from Duke University, Georgetown, and U.C. Berkeley. Jack also was a recognized writer and adjunct professor in the emerging field of Space Law, a subject he taught at the Hastings College of the Law and other universities in the Bay Area.

Former Space Science & Astrobiology Division Manager Cora Millena Dies

Corazon (Cora) Millena passed away on June 26. Cora began her career at NASA in 1985 and was a member of the Ames community for 39 years.  Her life story had a memorable connection to NASA and you’re encouraged to take a moment to read her personal essay.

Corazon Millena
Corazon (Cora) Millena

Born in the Philippines, Cora was a fifth-grade student in 1960 when she learned about NASA’s Echo-1 communications satellite. Inspired by the launch, she hoped to one day immigrate to the United States and work for the space agency.  

Cora worked hard to overcome many challenges in her life. She studied business administration in college and graduated from the Mapua Institutes of Technology in the Philippines. She finally realized her dream when she moved to San Jose with her family in 1975.  

As a program manager in the Space Science and Astrobiology Division at Ames, Cora worked on the Cassini mission, the Mars Climate Modeling Center, and on the Stratospheric Observatory for Infrared Astronomy (SOFIA) program. She was also a longtime member of the Ames Asian American, Native Hawaiian, and Pacific Islander community.

      Shallow Water Benthic Cover Type Classification using Hyperspectral Imagery in Kaneohe Bay, Oahu, Hawaii
      Lucas DiSilvestro
      Quantifying the changing structure and extent of benthic coral communities is essential for informing restoration efforts and identifying stressed regions of coral. Accurate classification of shallow-water benthic coral communities requires high spectral and spatial resolution, currently not available on spaceborne sensors, to observe the seafloor through an optically complex seawater column. Here we create a shallow water benthic cover type map of Kaneohe Bay, Oahu, Hawaii using the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) without requiring in-situ data as inputs. We first run the AVIRIS data through a semi-analytical inversion model to derive color dissolved organic matter, chlorophyll concentration, bottom albedo, suspended sediment, and depth parameters for each pixel, which are then matched to a Hydrolight simulated water column. Pure reflectance for coral, algae, and sand are then projected through each water column to create spectral endmembers for each pixel. Multiple Endmember Spectral Mixture Analysis (MESMA) provides fractional cover of each benthic class on a per-pixel basis. We demonstrate the efficacy of using simulated water columns to create surface reflectance spectral endmembers as Hydrolight-derived in-situ endmember spectra strongly match AVIRIS surface reflectance for corresponding locations (average R = 0.96). This study highlights the capabilities of using medium-fine resolution hyperspectral imagery to identify fractional cover type of localized coral communities and lays the groundwork for future spaceborne hyperspectral monitoring of global coral communities.

      Quantifying Uncertainty In Kelp Canopy Remote Sensing Using the Harmonized Landsat Sentinel-2 Dataset
      Atticus Cummings
      California’s giant kelp forests serve as a major foundation for the region’s rich marine biodiversity and provide recreational and economic value to the State of California. With the rising frequency of marine heatwaves and extreme weather onset by climate change, it has become increasingly important to study these vital ecosystems. Kelp forests are highly dynamic, changing across several timescales; seasonally due to nutrient concentrations, waves, and predator populations, weekly with typical growth and decay, and hourly with the tides and currents. Previous remote sensing of kelp canopies has relied on Landsat imagery taken with a eight-day interval, limiting the ability to quantify more rapid changes. This project aims to address uncertainty in kelp canopy detection using the Harmonized Landsat and Sentinel-2 (HLS) dataset’s zero to five-day revisit period. A random forest classifier was used to identify pixels that contain kelp, on which Multiple Endmember Spectral Mixture Analysis (MESMA) was then run to quantify intrapixel kelp density. Processed multispectral satellite images taken within 3 days of one another were paired for comparison. The relationship between fluctuations in kelp canopy density with tides and currents was assessed using in situ data from an acoustic doppler current profiler (ADCP) at the Santa Barbara Long Term Ecological Research site (LTER) and a NOAA tidal buoy. Preliminary results show that current and tidal trends cannot be accurately correlated with canopy detection due to other sources of error. We found that under cloud-free conditions, canopy detection between paired images varied on average by 42%. Standardized image processing suggests that this uncertainty is not created within the image processing step, but likely arises due to exterior factors such as sensor signal noise, atmospheric conditions, and sea state. Ultimately, these errors could lead to misinterpretation of remotely sensed kelp ecosystems, highlighting the need for further research to identify and account for uncertainties in remote sensing of kelp canopies.

      Kelp Us!: A Methods Analysis for Predicting Kelp Pigment Concentrations from Hyperspectral Reflectance
      Jasmine Sirvent
      Ocean color remote sensing enables researchers to assess the quantity and physiology of life in the ocean, which is imperative to understanding ecosystem health and formulating accurate predictions. However, without proper methods to analyze hyperspectral data, correlations between spectral reflectance and physiological traits cannot be accurately derived. In this study, I explored different methods—single variable regression, partial least squares regressions (PLSR), and derivatives—in analyzing in situ Macrocystis pyrifera (giant kelp) off the coast of Santa Barbara, California in order to predict pigment concentrations from AVIRIS hyperspectral reflectance. With derivatives as a spectral diagnostic tool, there is evidence suggesting high versus low pigment concentrations could be diagnosed; however, the fluctuations were within 10 nm of resolution, thus AVIRIS would be unable to reliably detect them. Exploring a different method, I plotted in situ pigment measurements — chlorophyll a, fucoxanthin, and the ratio of fucoxanthin to chlorophyll a—against hyperspectral reflectance that was resampled to AVIRIS bands. PLSR proved to be a more successful model because of its hyperdimensional analysis capabilities in accounting for multiple wavelength bands, reaching R2 values of 0.67. Using this information, I constructed a model that predicts kelp pigments from simulated AVIRIS reflectance using a spatial time series of laboratory spectral measurements and photosynthetic pigment concentrations. These results have implications, not only for kelp, but many other photosynthetic organisms detectable by hyperspectral airborne or satellite sensors. With these findings, airborne optical data could possibly predict a plethora of other biogeochemical traits. Potentially, this research would permit scientists to acquire data analogous to in situ measurements about floating matters that cannot financially and pragmatically be accessed by anything other than a remote sensor.

      Correlations Between SSHa and Chl-a Concentrations in the Northern South China Sea
      Isabelle Cobb
      Sea surface height anomalies (SSHa)–variations in sea surface height from climatological averages–occur on seasonal timescales due to coastal upwelling and El Niño-Southern Oscillation (ENSO) cycles. These anomalies are heightened when upwelling plumes bring cold, nutrient-rich water to the surface, and are particularly strong along continental shelves in the Northern South China Sea (NSCS). This linkage between SSHa and nutrient availability has interesting implications for changing chlorophyll-a (chl-a) concentrations, a prominent indicator of phytoplankton biomass that is essential to the health of marine ecosystems. Here, we evaluate the long-term (15 years) relationship between SSHa and chl-a, in both satellite remote sensing data and in situ measurements. Level 3 SSHa data from Jason 1/2/3 satellites and chl-a data from MODIS Aqua were acquired and binned to monthly resolution. We found a significant inverse correlation between SSHa and chl-a during upwelling months in both the remote sensing (Spearman’s R=-0.57) and in situ data, with higher resolution in situ data from ORAS4 (an assimilation of buoy observations from 2003-2017) showing stronger correlations (Spearman’s R=-0.75). In addition, the data reveal that the magnitude of SSH increases with time during instances of high correlation, possibly indicating a trend of increased SSH associated with reduced seasonal chl-a concentrations. Thus, this relationship may inform future work predicting nutrient availability and threats to marine ecosystems as climate change continues to affect coastal sea surface heights.

      Exploring Coastal Sea Surface Temperature Anomalies and their effect on Coastal Fog through analyzing Plant Phenology
      Alyssa Tou
      Marine heat waves (MHW) have been increasing in frequency, duration and intensity, giving them substantial potential to influence ecosystems. Do these MHWs sufficiently enhance coastal precipitation such that plant growth is impacted? Recently, the Northeast Pacific experienced a long, intense MHW in 2014/2015, and another short, less intense MHW in 2019/2020. Here we investigate how the intensity and duration of MHWs influence the intensity and seasonal cycle of three different land cover types (‘grass’, ‘trees’, and a combination of both ‘combined’’) to analyze plant phenology trends in Big Sur, California. We hypothesize that longer intense MHWs decrease the ocean’s evaporative capacity, decreasing fog, thus lowering plant productivity, as measured by Normalized Difference Vegetation Index (NDVI). Sea surface temperature (SST) and NDVI data were collected from the NOAA Coral Reef Watch, and NASA MODIS/Terra Vegetation Indices 16-Day L3 Global 250m products respectively. Preliminary results show no correlation (R2=0.02) between SSTa and combined NDVI values and no correlation (R2=0.01) between SST and NDVI. This suggests that years with anomalously high SST do not significantly impact plant phenology. During the intense and long 2014/2015 MHW, peak NDVI values for ‘grass’ and ‘combined’ pixels were 2.0 and 1.7 standard deviations above the climatological average, while the shorter 2019/2020 MHW saw higher peaks of 3.2 and 2.4 standard deviations. However, the ‘grass’, ‘tree’ and ‘combined’ NDVI anomalies were statistically insignificant during both MHWs, showing that although NDVI appeared to increase during the shorter and less intense MHW, these values may be attributed to other factors. The data qualitatively suggest that MHW’s don’t impact the peak NDVI date, but more data at higher temporal resolution are necessary. Further research will involve analyzing fog indices and exploring confounding variables impacting NDVI, such as plant physiology, anthropogenic disturbance, and wildfires. In addition, it’s important to understand to what extent changes in NDVI are attributed to the driving factors of MHWs or the MHWs themselves. Ultimately, mechanistically understanding the impacts MHW intensity and duration have on terrestrial ecosystems will better inform coastal community resilience.

      Remote sensing of poor air quality in mountains: A case study in Kathmandu, Nepal
      Danielle Jones
      Urban activity produces particulate matter in the atmosphere known as aerosol particles. These aerosols can negatively affect human health and cause changes to the climate system. Measures for aerosols include surface level PM2.5 concentration and aerosol optical depth (AOD). Kathmandu, Nepal is an urban area that rests in a valley on the edge of the Himalayas and is home to over three million people. Despite the prevailing easterly winds, local aerosols are mostly concentrated in the valley from the residential burning of coal followed by industry. Exposure to PM2.5 has caused an estimated ≥8.6% of deaths annually in Nepal. We paired NASA satellite AOD and elevation data, model  meteorological data, and local AirNow PM2.5 and air quality index (AQI) data to determine causes of variation in pollutant measurement during 2023, with increased emphasis on the post-monsoon season (Oct. 1 – Dec. 31). We see the seasonality of meteorological data related to PM2.5 and AQI. During periods of low temperature, low wind speed, and high pressure, PM2.5 and AQI data slightly diverge. This may indicate that temperature inversions increase surface level concentrations of aerosols but have little effect on the total air column. The individual measurements of surface pressure, surface temperature, and wind speed had no observable correlation to AOD (which was less variable than PM2.5 and AQI over the entire year). Elevation was found to have no observable effect on AOD during the period of study. Future research should focus on the relative contributions of different pollutants to the AQI to test if little atmospheric mixing causes the formation of low-altitude secondary pollutants in addition to PM2.5 leading to the observed divergence in AQI and PM2.5.

      Analyzing the Transport and Impact of June 2023 Canadian Wildfire Smoke on Surface PM2.5 Levels in Allentown, Pennsylvania
      Madison Holland
      The 2023 wildfire season in Canada was unparalleled in its severity. Over 17 million hectares burned, the largest area ever burned in a single season. The smoke from these wildfires spread thousands of kilometers, causing a large population to be exposed to air pollution. Wildfires can release a variety of air pollutants, including fine particulate matter (PM2.5). PM2.5 directly affects human health – exposure to wildfire-related PM2.5 has been associated with respiratory issues such as the exacerbation of asthma and chronic obstructive pulmonary disease. In June 2023, smoke from the Canadian wildfires drifted southward into the United States. The northeastern United States reported unhealthy levels of air quality due to the transportation of the smoke. In particular, Pennsylvania reported that Canadian wildfires caused portions of the state to have “Hazardous” air quality. Our research focused on how Allentown, PA experienced hazardous levels of air quality from this event. To analyze the concentrations of PM2.5 at the surface level, NASA’s Hazardous Air Quality Ensemble System (HAQES) and the EPA’s Air Quality System (AQS) ground-based site data were utilized. By comparing HAQES’s forecast of hazardous air quality events with recorded daily average PM2.5 with the EPA’s AQS, we were able to compare how well the ensemble system was at predicting total PM2.5 during unhealthy air quality days. NOAA’s Hybrid Single-Particle Lagrangian Integrated Trajectory model, pyrsig, and the Canadian National Fire Database were used. These datasets revealed the trajectory of aerosols from the wildfires to Allentown, Pennsylvania, identified the densest regions of the smoke plumes, and provided a map of wildfire locations in southeastern Canada. By integrating these datasets, we traced how wildfire smoke transported aerosols from the source at the ground level.

      Trends and Transport of Tropospheric Ozone From New York City to Connecticut in the Summer of 2023
      Michele Iraci
      Tropospheric Ozone, or O₃, is a criteria pollutant contributing to most of Connecticut and New York City’s poor air quality days. It has adverse effects on human health, particularly for high-risk individuals. Ozone is produced by nitrogen oxides and volatile organic compounds from fuel combustion reacting with sunlight. The Ozone Transport Region (OTR) is a collection of states in the Northeast and Mid-Atlantic United States that experience cross-state pollution of O₃. Connecticut has multiple days a year where O₃ values exceed the National Ambient Air Quality Standards requiring the implementation of additional monitoring and standards because it falls in the OTR. Partially due to upstream transport from New York City, Connecticut experiences increases in O₃ concentrations in the summer months. Connecticut has seen declines in poor air quality days from O₃ every year due to the regulations on ozone and its precursors. We use ground-based Lidar, Air Quality System data, and a back-trajectory model to examine a case of ozone enhancement in Connecticut caused by air pollutants from New York between June and August 2023. In this time period, Connecticut’s ozone enhancement was caused by air pollutants from New York City. As a result, New York City and Connecticut saw similar O₃ spikes and decline trends. High-temperature days increase O₃ in both places, and wind out of the southwest may transport O₃ to Connecticut. Production and transport of O₃ from New York City help contribute to Connecticut’s poor air quality days, resulting in the need for interstate agreements on pollution management.

      Correlations Between the Planetary Boundary Layer Height and the Lifting Condensation Level
      Stefan Sundin
      The Planetary Boundary Layer (PBL) characterizes the lowest layer in the atmosphere that is coupled with diurnal heating at the surface. The PBL grows during the day as solar heating causes pockets of air near the surface to rise and mix with cooler air above. Depending on the type of terrain and surface albedo that receives solar heating, the depth of the PBL can vary to a great extent. This makes PBL height (PBLH) a difficult variable to quantify spatially and temporally. While several methods have been used to obtain the PBLH such as wind profilers and lidar techniques, there is still a level of uncertainty associated with PBLH. One method of predicting seasonal PBLH fluctuation and potentially lessening uncertainty that will be discussed in this study is recognizing a correlation in PBLH with the lifting condensation level (LCL). Like the PBL, the LCL is used as a convective parameter when analyzing upper air data, and classifies the height in the atmosphere at which a parcel becomes saturated when lifted by a forcing mechanism, such as a frontal boundary, localized convergence, or orographic lifting. A reason to believe that PBLH and LCL are interconnected is their dependency on both the amount of surface heating and moisture that is present in the environment. These thermodynamic properties are of interest in heavily populated metropolitan areas within the Great Plains, as they are more susceptible to severe weather outbreaks and associated economic losses. Correlations between PBLH and LCL over the Minneapolis-St. Paul metropolitan statistical area during the summer months of 2019-2023 will be discussed.

      Coupling of Chlorophyll-a Concentrations and Aerosol Optical Depth in the Subantarctic Southern Ocean and South China Sea (2019-2021)
      Angelica Kusen
      Air-sea interactions form a complex feedback mechanism, whereby aerosols impact physical and biogeochemical processes in marine environments, which, in turn, alter aerosol properties. One key indicator of these interactions is chlorophyll-a (Chl-a), a pigment common to all phytoplankton and a widely used proxy for primary productivity in marine ecosystems. Phytoplankton require soluble nutrients and trace metals for growth, which typically come from oceanic processes such as upwelling. These nutrients can also be supplied via wet and dry deposition, where atmospheric aerosols are removed from the atmosphere and deposited into the ocean. To explore this interaction, we analyze the spatial and temporal variations of satellite-derived chl-a and AOD, their correlations, and their relationship with wind patterns in the Subantarctic Southern Ocean and the South China Sea from 2019 to 2021, two regions with contrasting environmental conditions.
      In the Subantarctic Southern Ocean, a positive correlation (r²= 0.26) between AOD and Chl-a was found, likely due to dust storms following Austrian wildfires. Winds deposit dust aerosols rich in nutrients, such as iron, to the iron-limited ocean, enhancing phytoplankton photosynthesis and increasing chl-a. In contrast, the South China Sea showed no notable correlation (r² = -0.02) between AOD and chl-a. Decreased emissions due to COVID-19 and stricter pollution controls likely reduced the total AOD load and shifted the composition of aerosols from anthropogenic to more natural sources.
      These findings highlight the complex interrelationship between oceanic biological activity and the chemical composition of the atmosphere, emphasizing that atmospheric delivery of essential nutrients, such as iron and phosphorus, promotes phytoplankton growth. Finally, NASA’s recently launched PACE mission will contribute observations of phytoplankton community composition at unprecedented scale, possibly enabling attribution of AOD levels to particular groups of phytoplankton.

      Estimating CO₂ Emission from Rocket Plumes Using in Situ Data from Low Earth Atmosphere
      Chris Hautman
      Rocket emissions in the lower atmosphere are becoming an increasing environmental concern as space exploration and commercial satellite launches have increased exponentially in recent years. Rocket plumes are one of the few known sources of anthropogenic emissions directly into the upper atmosphere. Emissions in the lower atmosphere may also be of interest due to their impacts on human health and the environment, in particular, ground level pollutants transported over wildlife protected zones, such as the Everglades, or population centers near launch sites. While rockets are a known source of atmospheric pollution, the study of rocket exhaust is an ongoing task. Rocket exhaust can have a variety of compositions depending on the type of engine, the propellants used, including fuels, oxidizers, and monopropellants, the stoichiometry of the combustion itself also plays a role. In addition, there has been increasing research into compounds being vaporized in atmospheric reentry. These emissions, while relatively minimal compared to other methods of travel, pose an increasing threat to atmospheric stability and environmental health with the increase in human space activity. This study attempts to create a method for estimating the total amount of carbon dioxide released by the first stage of a rocket launch relative to the mass flow of RP-1, a highly refined kerosene (C₁₂H₂₆)), and liquid oxygen (LOX) propellants. Particularly, this study will focus on relating in situ CO₂ emission data from a Delta II rocket launch from Vandenberg Air Force Base on April 15, 1999, to CO₂ emissions from popular modern rockets, such as the Falcon 9 (SpaceX) and Soyuz variants (Russia). The findings indicate that the CO₂ density of any RP-1/LOX rocket is 6.9E-7 times the mass flow of the sum of all engines on the first stage. The total mass of CO₂ emitted can be further estimated by modeling the volume of the plume as cylindrical. Therefore, the total mass can be calculated as a function of mass flow and first stage main engine cutoff. Future CO₂ emissions on an annual basis are calculated based on these estimations and anticipated increases in launch frequency.

      How are different land cover types affected by land subsidence on the U.S. Atlantic Coast?
      Jordan DiPrima
      Land subsidence is a frequently overlooked geologic hazard that is caused by natural processes and, more recently, anthropogenic stressors. The goal of this study is to observe subsidence trends and hotspots among land cover types on Virginia’s Eastern Shore and Long Island, New York. This study utilizes interferometric synthetic aperture radar, or InSAR, satellite data from Sentinel-1 to map vertical land motion from 2017 to 2023. Land cover data were sourced from Landsat 8 satellite imagery. Subsidence was mapped within the following land cover types on the Eastern Shore: urban, wetland, cropland, temperate or sub-polar grassland, temperate or sub-polar shrubland, mixed forest, and temperate or subpolar needleleaf forest. These land cover types have mean vertical velocities ranging from -0.2 mm/yr to -5.2 mm/yr. Results suggest that land subsidence is most severe in cropland areas on the Eastern Shore, with a mean vertical velocity of -5.2 mm/yr. In contrast, wetlands display the most subsidence on Long Island with a mean vertical velocity of -2.1 mm/yr. Long Island lacked distinct trends among land cover types and instead showed evidence of subsidence hotspots. These hotspots exist in the following land cover types: temperate or sub-polar grassland, barren lands, wetland, cropland, and temperate or sub-polar broadleaf deciduous forest. Overall, Eastern Shore croplands and Long Island wetlands were determined to be the most susceptible land cover types. These findings highlight regions at risk of sea level rise, flooding, and coastal erosion as a result of subsidence. With further research, we can map subsiding landscapes on a global scale to improve resource allocation and mitigation techniques.

      Total Thermokarst Lake Changes on the Seward Peninsula, Alaska: 2016 to 2024
      Isabelle Peterson
      Thermokarst landscapes have and will continue to change as the arctic landscape warms due to climate change. Permafrost underlies much of these arctic landscapes, and as it melts, thermokarst landscapes are left behind. The Seward Peninsula in Alaska has an abundance of these landscapes, and thermokarst lakes are present in the northernmost portion. Several lakes have come and gone, but with increasing climate instability and warming of the area, there is a possibility of more permafrost melting, creating more of these lakes. To capture these changes, Harmonized Landsat Sentinel-2 (HLS) imagery were used to create annual lake maps of the northern portion of the Seward Peninsula from 2016 to 2024. Much of the methodology was informed from Jones et al. (2011); however, their study used eCognition, while the present study used ArcGIS Pro. This caused some differences in results likely due to the differences in software, satellite imagery, and the proposed study area. Lake number changes were observed annually. From this annual change, several 10 to 40 ha lakes disappeared and reappeared within the study period, along with smaller lakes filling in where larger lakes once were. Thermokarst lake drainage is a process described by Jones and Arp (2015) which has devastating geomorphological impacts on the surrounding area, creating large drainage troughs which diminish surrounding permafrost in a quick time frame. To capture these events and overall changes, satellite imagery is essential. This is especially true in remote regions which are hard to reach by foot and require flight missions to be scheduled over the area for aerial photography. However, LVIS and other higher resolution aerial instruments would provide higher accuracy when identifying smaller lakes, as satellite imagery does not accurately capture lakes below 1 ha in the study area. This assertion is made due to conflicting results compared to Jones et al (2011). While the methodologies of this study have been executed manually, Qin, Zhang, and Lu (2023) have proposed the idea of using Sentinel-2 imagery to map thermokarst lakes through automatic methods. While automatization has not yet been perfected, the potential is there and can be used to analyze thermokarst areas effectively. With more satellite imagery, annual, monthly, and potentially daily changes can be captured in favorable months to monitor changing landscapes in arctic regions. Thermokarst lakes have been changing, and monitoring them can help in the process of understanding the changing climate in arctic areas, especially through the lens melting permafrost.

      Finding Refuge in Climate Crisis: Analyzing the Differences between Refugia and Non-Refugia in the Northern Philippines Using Remote Sensing
      Emmanelle Cuasay
      Refugia are areas that are characterized by stable environmental conditions that can act as a refuge for species as Earth’s climate warms. In this study, fourteen Harmonized Landsat Sentinel-2 images from February 2014 – March 2024 of the northern Philippines region were used. The region of interest is the terrestrial biome by Lake Taal. Normalized Difference Vegetation Index (NDVI) maps were created from all fourteen images to determine the NDVI 25th highest quartiles of the long-term average NDVI images and of a dry and wet year NDVI image. These values were then used to create refugia and non-refugia maps using ArcGIS Pro. Land cover data from Sentinel-2 and a digital elevation model (DEM), using the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), were plotted in ArcGIS Pro to determine the slope and aspect of the area. Global Ecosystems Dynamics Investigation (GEDI) data were used to look at forest height of the study area, and the distribution of forest height, slope, aspect, and elevation were plotted to determine their probability densities in refugia and non-refugia areas. Results of this study show increased biomass in refugia areas. This suggests that conservation practices are crucial to aid in the preservation of biodiversity and biomass within these refugia areas.

      Site-Based Observations of a Saharan Dust Storm’s Impacts on Evapotranspiration in North-Central Florida
      Jayce Crayne
      Saharan dust storms serve an important role in the western Atlantic’s climate in their contribution to Earth’s radiation budget, modulating sea surface temperatures (SSTs), fertilizing ecosystems, and suppressing cloud and precipitation patterns (Yuan et al., 2020). However, Saharan dust storms are expected to become less frequent in this region as SSTs continue to rise (Yuan et al., 2020). Predicting the climate response to this change requires a keen understanding of how the presence of these storms affect evapotranspiration (ET) and its indicators. This study utilizes site-based observational data from an AmeriFlux tower near Gainesville, FL recorded during a large dust storm in late June 2020. The storm’s progression was documented using satellite imagery from Aqua and Terra and aerosol optical depth (AOD) measurements from an Aerosol Robotic Network (AERONET) station co-located with the AmeriFlux tower. Indicators of ET such as surface air temperature, vapor pressure deficit, photosynthetic photon flux density, and net radiation were analyzed. Findings were compared to modeled ET and latent energy flux reanalysis data provided by the Global Land Data Assimilation System (GLDAS). Both model simulations and on-site observations support that ET decreased during the days dust concentrations were heaviest and for a short time thereafter. Cloud cover data adopted from meteorological aerodrome reports (METARs) provided by an automated surface observing system (ASOS) located in Gainesville showed that clouds were not a major contributor in decreasing ET during the days of heaviest dust. The results of this study show a considerable decrease in ET as a result of dust aerosols. Further research is necessary to determine whether changes in ET due to Saharan dust storms are significant enough to alter climates in the western Atlantic and, if so, what the climate response will be if the frequency of storms decreases.

      Brandon Wilson
      Biodiverse regions across California remain vulnerable to harmful wildfires year round. Quantifying and measuring these regions’ wildfire resilience is necessary for understanding where/how to allocate environmental resources. Several ecological wildfire studies have been conducted utilizing artificial intelligence and remote sensing to analyze and predict biodiversity damage across wildfire prone regions, including Northern Algeria and Arkansas, USA. The current case study aims to analyze biodiversity damage from the 2023 Csarf Smith River Complex Fire in Six Rivers National Forest, California and predict the difference in Normalized Burn Ratio (dNBR) and difference in Normalized Difference Vegetation Index (dNDVI) for 2025 and 2028 using remote-sensing-based random forest (RF) regression. Furthermore, to observe, holistically, a practical method California has implemented to address state-wide wildfire damage, the 2019 California Wildfire Fund (AB 1054 and AB 111) was evaluated using the synthetic control method (SCM). For this case study, remote sensing data from the United States Geological Survey (USGS) and NASA (Landsat 9 Satellite C2 L2, TerraClimate and the Land Data Assimilation System) were utilized for processing relevant spectral indexes for the RF. Data from NOAA, Energy Information Agency, International Monetary Fund and Bureau of Economic Analysis were utilized as synthetic control datasets to evaluate the effects of the 2019 California Wildfire Fund. Elevated topography in this study area is susceptible to high severity burn effects, while less elevated topography burns less. This result affected dNBR and dNDVI predictions as elevated areas seemingly did not have strong resilience to rampant burns. This demonstrates a direct correlation to potential lower transpiration rates for elevated areas, warranting further analysis. Results of low variance, post-treatment, between the treated unit and the synthetic control unit, poses concern for the positive effect of the 2019 Wildfire Fund.

      Describing changes in evapotranspiration following the 2020 Creek Fire in the southern Sierra Nevada
      Carrie Hashimoto
      Climatic warming and high tree density have caused larger and more severe wildfires to occur in western United States forests over time. Wildfires affect both the hydrology and ecology of forests via alterations to the water balance (e.g., evapotranspiration, streamflow, infiltration, and more) and could shift vegetation communities and subsequent ecosystem structure and function. This project explores ecological characteristics of a landscape that predict the extent to which the Creek Fire in the southern Sierra Nevada has affected evapotranspiration. Strides in understanding of consequential evapotranspiration changes can create pathways to address emerging forest health challenges posed by similar western fires. For analysis, various remote sensing and modeled data were collected from OpenET, the North American Land Data Assimilation System, TerraClimate, Harmonized LandSat Sentinel-2 data, and the Shuttle Radar Topography Mission. Multiple linear regression and generalized additive models were constructed. Relative change in evapotranspiration served as the response variable. Model covariates included average temperature, total precipitation in the preceding months, average soil moisture, elevation, slope, aspect, northness, latitude, pre-fire normalized difference vegetation index (NDVI), and post-fire change in normalized burn ratio (dNBR). Best subset selection with cross validation demonstrated minimization of cross-validation error with a 7-covariate model. This reduced model yields lower complexity and more interpretability while sustaining an adjusted R2 of 0.626, compared to the full model’s adjusted R2 of 0.663. A reduced generalized additive model (GAM) with interaction terms drawn from the linear model variable selection demonstrated an adjusted R2 of 0.695, indicating a better fit that comes at the cost of reduced interpretability and higher computational requirements than the linear models. The goal of this work is to disentangle environmental indicators of post-fire evapotranspiration change, such that predictive modeling of future wildfire impacts on evapotranspiration can be achieved.

      Using NDVI as a Proxy for GPP to Predict Carbon Dioxide Fluxes
      Angelina De La Torre
      Climate change, driven primarily by greenhouse gases, poses a threat to the future of our planet. Among these gases is carbon dioxide (CO₂), which has a much longer atmospheric residence time compared to other greenhouse gases. One potential factor in reducing atmospheric CO₂ enrichment is plant productivity. Gross Primary Productivity (GPP) estimates the amount of CO₂ fixed during photosynthesis. The Normalized Difference Vegetation Index (NDVI) provides insight into the health of an ecosystem by measuring the density and greenness of vegetation. Therefore, it can be inferred that there is a relationship between NDVI and GPP, as greener plants are likely more productive. In this study, we used NDVI as a proxy for GPP and analyzed the effect NDVI had on CO₂ fluxes during California’s wet season between January and March 2023 in a restored tidal freshwater wetland. GPP and CO₂ flux data were obtained from the Dutch Slough AmeriFlux tower in Oakley, California. Landsat data were used to calculate the average NDVI. The influence of NDVI on GPP was assessed using linear regression. A second linear regression was then performed using NDVI and CO₂ flux, of which GPP is one component. We anticipate that wetlands with greater vegetation density will have lower CO₂ emissions.

      Because Landsat data scans in 16-day intervals, daily variation in NDVI could not be observed. This translates to a frequency discrepancy between the Landsat and AmeriFlux data, as AmeriFlux towers measure in half-hour intervals. Additionally, the wet season represented was limited by data availability, as the data before 2023 were unavailable. Despite data limitations in this study, the outlined process could be repeated in various wetland and climate classifications for further analysis of a larger sample size. This study could assist in developing strategies to increase CO₂ sequestration in an attempt to slow the effects of climate change.

      Using Machine Learning to Assess Relationships between NDVI and Net Carbon Exchange During the COVID-19 Pandemic
      Samarth Jayadev
      Understanding the movement of carbon between Earth’s land surface and atmosphere is essential for ecosystem monitoring, creating climate change mitigation strategies, and assessing the carbon budget on national to global scales. Measures of greenness serve as indicators of processes such as photosynthesis that control carbon exchange and are vital in modeling of carbon fluxes. NASA’s Orbiting Carbon Observatory (OCO-2) provides high quality measurements of column-averaged CO₂ concentrations that can be used to derive net carbon exchange (NCE), a measure of CO₂ flux between terrestrial ecosystems and the atmosphere.
      From OCO-2, NCE data collected at the land nadir, land glint satellite position combined with in situ sampling can provide accurate measurements on a 1°x1° scale suitable for carbon flux characterization across the contiguous United States (CONUS). Normalized difference vegetation index (NDVI), which ranges from -1 to +1, measures the greenness of vegetation, serving as an indicator of plant density and health. This can help to understand ecosystem to carbon-cycle interactions and be leveraged for determining patterns with NCE. We examined the relationship between NDVI and NCE across CONUS during 2020 using Gradient Boosting Decision Trees (GBDT) which specialize in classifying and predicting non-linear relationships. This algorithm takes multiple weak learners (decision trees) and combines their predictions in an iterative ensemble method to improve prediction accuracy. Feature and permutation importance tests found that January and August (trough and peak NDVI, respectively) were the highest weighted predictor variables related to NCE. The dataset was split in a 90% training 10% test ratio across latitude/longitude grid cells to assess and verify model performance. Using the mean squared error loss function and hyperparameters with optimal estimators, tree depth, sample split, and learning rate the algorithm was able to converge the test predictions to match the deviance of the training data. The gradient boosting model can be applied to different months and years of NDVI/NCE to further explore these relationships or a multitude of research questions. Further studies should consider integrating land use and land cover change variables such as bare land and urbanization to improve predictions of NCE.

      Deep-learning Derived Spaceborne Canopy Structural Metrics Predict Forest Carbon Fluxes
      Makai Ogoshi
      Terrestrial and airborne lidar data products describing canopy structure are potent predictors of forest carbon fluxes, but whether satellite data products produce similarly robust indicators of canopy structure is not known. The assessment of contemporary spaceborne lidar and other remote sensing data products as predictors of carbon fluxes is crucial to next generation instrument and data product design and large-spatial scale modeling. We investigated relationships between deciduous broadleaf forest canopy structure, derived from deep-learning models created with lidar data from GEDI and optical imagery from Sentinel-2, and forest carbon exchange. These included comparisons to in-situ continuous net ecosystem exchange (NEE), gross primary production (GPP), and net primary production (NPP). We find that the mean  canopy height from the gridded spaceborne product has a strong correlation with forest NPP, similar to prior analysis with ground-based lidar (portable canopy lidar; PCL). For comparison to NPP, heights taken from the gridded spaceborne product were compared by overlapping the product with nine terrestrial forest sites from the National Ecological Observatory Network (NEON). We used standard deviation of canopy height as a measure of canopy structural complexity. Complexity derived from the gridded spaceborne product does not show the same strong correlation with NPP as found when using PCL. Mean annual GPP and NEE across five years were compared to the gridded spaceborne product at six Fluxnet2015-tower sites with continuous, gap-filled carbon flux data. When compared to in-situ flux tower data, neither mean canopy height nor structural complexity strongly correlate to annual NEE or GPP. Primarily, the finding that derived spaceborne products exhibit a strong correlation between forest canopy height and NPP will advance global-scale application of forest-carbon flux predictions. Secondarily, a variety of limitations highlight shortcomings in the current terrestrial flux data network. A small number of available study sites, both spatially and temporally, and lack of resolution in vertical complexity of canopy structure both contribute to uncertainty in assessing the relationships to NEE and GPP.

      Porewater Methane Concentrations Vary Significantly Across A Freshwater Tidal Wetland
      Sebastian Reed
      Methane is a potent greenhouse gas that is over 80 times more powerful than CO₂ at trapping heat and accounts for an estimated 30% of global temperature rise associated with climate change. The largest natural source of methane worldwide is wetlands. Despite the role of methane in driving climate change, the magnitude of global annual wetland methane flux remains highly uncertain. This study analyzes the effects of greenness (assessed using Normalized Difference Vegetation Index; NDVI), plant species composition, rooting depth, atmospheric methane concentration, and plant longevity on porewater methane concentration at the Kimages Rice Rivers Center tidal freshwater wetland. Samples for atmospheric and porewater concentrations were conducted in situ in June 2024. For each sampling location (n = 23) we collected whole air samples (WAS) 2m above the marsh surface and porewater samples 5cm below the marsh surface. We visually assessed species composition at each sample location, with 12 species of wetland plants present overall. We used the TRY plant database to find the rooting depth, leaf nitrogen content, and lifespan of each species. Drone multispectral data from 2023 was used to estimate NDVI values. These variables were compared to the pore water methane concentration via stepwise linear regression. Leaf N content, NDVI, plant species, and WAS sampling did not show statistically significant correlation to porewater methane concentration. Rooting depth showed a slight positive correlation with porewater methane (alpha = 0.1, p = 0.08, R^2 = 0.1). Samples with only perennial plants (as opposed to annual plants) had a higher mean value of porewater methane (p = 0.1). Analyzing porewater methane provides insight as to what wetland components affect methanogenesis and methane release, which aids in assessing which plant functional traits are most responsible for driving or mitigating climate change. Results from this study and future research in this area has the potential to more accurately assess how methane cycles through wetlands to the atmosphere.

      Understanding the vertical profile of CO₂ concentration: How carbon dioxide levels change with altitude
      Nohemi Rodarte
      Carbon dioxide (CO₂) is one of the main greenhouse gasses that contribute to global warming.While the relationship between CO₂ concentrations and land cover types, such as forests and urban areas, is well documented, there is limited knowledge of how CO₂ concentrations vary with altitude at fine spatial scales. Guided by our hypothesis that CO₂ levels vary with altitude and increase with elevation, we used airborne data collected from the B200 aircraft, which flew at different altitudes (400 to 1200 feet) above the urban area of Hopewell, Virginia, between 9:40 AM and 10:40 AM. We analyzed the CO₂ concentrations recorded by the flight to obtain the median and range for each 100 feet of altitude. Our results reveal that carbon dioxide concentrations varied significantly across the range of altitudes investigated. Within the area studied, CO₂ concentrations were found to range between 410 and 470 ppm. The distribution of these concentrations along the altitude gradient shows a bimodal pattern, with notable peaks at altitudes of 700 to 800 feet and 1100 to 1200 feet. Although CO₂ levels were present at all measured altitudes, there was a noticeable drop in the mean concentration at 800 feet,which then stabilized until reaching 1,000 feet before rising again. This pattern indicates that the concentrations of this greenhouse gas are not uniformly distributed with altitude, but rather vary significantly, showing higher concentrations at certain elevations and lower concentrations at others. The CO₂ distribution fluctuates with altitude, showing higher or lower levels at specific heights rather than a smooth gradient, indicating that altitude impacts CO₂ concentrations. While we did not identify the drivers of this change, future studies could evaluate how factors such as surface emissions, atmospheric mixing, and local conditions may contribute to vertical CO₂ profiles, since the altitudes we considered in this research are within the troposphere.

      Linking NDVI with CO₂ and CH₄ Fluxes: Insights into Vegetation and Urban Source-Sink Dynamics in the Great Dismal Swamp
      Camille Shaw
      In recent years, carbon dioxide, methane, and other greenhouse gases have gained attention because of their contribution to the rise in Earth’s global mean temperature. Methane and carbon dioxide have various sources and sinks, but an expanding array of sources have created a need to assess ongoing change in carbon balance. This study aims to quantify the relationship between Normalized Difference Vegetation Index, or NDVI, and methane and carbon dioxide fluxes. We measured carbon dioxide and methane concentrations within the boundary layer using the PICARRO instrument, focusing on the Great Dismal Swamp, a forested wetland, and surrounding areas in the Eastern Mid-Atlantic Region. Data collection occurred at various times of day and along different flight paths in 2016, 2017, and 2024, with each year representing data from a single season, either spring or fall, for temporal analysis. We calculated methane and carbon dioxide fluxes along the flight paths using airborne eddy covariance, a method for capturing accurate flux measurements while accounting for the mixing of gases in the boundary layer caused by heat. Additionally, we calculated NDVI for this area using NASA’s Landsat 8 and 9 satellite imagery. Analysis of the afternoon flight data revealed a negative linear correlation between NDVI and carbon dioxide flux. Urban areas, characterized by low NDVI, exhibit a positive carbon dioxide flux as a consequence of emissions from vehicles, while forested areas, with high NDVI, show a negative carbon dioxide flux because of photosynthesis. In contrast, methane flux shows minimal correlation with NDVI. The lack of correlation arises because forested wetlands, with high NDVI, emit substantial amounts of methane, while urban areas, despite having low NDVI, still produce significant methane emissions from landfills and industrial activities. Future research could further investigate how seasonal and diurnal variations influence the correlations between NDVI and greenhouse gases by collecting comprehensive data across all seasons within a given year and at various times of the day.
