Leveraging High Resolution PlanetScope Imagery to Quantify oil slick Spatiotemporal Variability in the Santa Barbara Channel
Emory Gaddis, Colgate University
Located within the Santa Barbara Channel of California, Coal Oil Point is one of the world’s largest hydrocarbon seep fields. The area’s natural hydrocarbon seepage and oil production have sustained both scientific interest and commercial activity for decades. Historically, indigenous peoples in the region utilized the naturally occurring tar for waterproofing baskets, establishing early evidence of the natural presence of hydrocarbons long before modern oil extraction began. Gaseous hydrocarbons are released from the marine floor through the process of seeping, wherein a buildup of reservoir pressure relative to hydrostatic pressure causes bubbles, oily bubbles, and droplets to rise to the surface. This hydrocarbon seepage is a significant source of Methane CH4—a major greenhouse gas––emissions into the atmosphere. Current limitations of optical remote sensing of oil presence and absence in the ocean leverage geometrical as well as biogeochemical factors and include changes in observed sun glint, sea surface damping, and wind roughening due to changes in surface oil concentrations. We leverage high-resolution (3m) surface reflectance observations obtained from PlanetScope to construct a time series of oil slick surface area spanning 2017 to 2023 within the Coal Oil Point seep field. Our initial methods are based on manual annotations performed within ArcGIS-Pro. We assess potential relationships between wind speed and oil slick surface area to support a sensitivity analysis of our time series. Correcting for confounding outside factors (e.g., wind speed) that modify oil slick surface area improves determination of oil slick surface area and helps test for changes in natural seepage rates and whether anthropogenic activities, such as oil drilling, alter natural oil seepage. Future investigations into oil slick chemical properties and assessing how natural seepage impacts marine and atmospheric environments (e.g., surface oil releases methane into the atmosphere) can help to inform the science of optimizing oil extraction locations.

Investigating Airborne LiDAR Retrievals of an Emergent South African Macroalgae
Rachel Emery, The University of Oklahoma
Right now, the world is facing an unprecedented biodiversity crisis, with areas of high biodiversity at the greatest risk of species extinction. One of these biodiversity hotspots, the Western Cape Province of South Africa, features one of the world’s largest unique marine ecosystems due to the extensive growth of canopy forming kelps, such as Macrocystis and Ecklonia, which provide three-dimensional structure important for fostering biodiversity and productivity. Canopy-forming kelps face increasing threats by marine heatwaves and pollution related to climate change and local water quality perturbation. Though these ecosystems can be monitored using traditional field surveying methods, remote sensing via airborne and satellite observations support improved spatial coverage and resample rates, plus extensive historical continuity for tracking multidecadal scale changes. Passive remote sensing observations—such as those derived using observations from NASA’s Airborne Visible-Infrared Imaging Spectrometer – Next Generation (AVIRIS-NG) —provide high resolution, hyperspectral imagery of oceanic environments anticipated to help characterize community dynamics and quantify macroalga physiological change. Active remote sensing observations, e.g., Light Detection and Ranging (LiDAR), are less understood in terms of applications to marine ecosystems, but are anticipated to support novel observations of vertical structure not supported using passive aquatic remote sensing. Here we investigate the potential to observe an emergent canopy-forming macroalgae (i.e., Ecklonia, which can extend more than a decimeter above the ocean’s surface) using NASA’s Land, Vegetation, and Ice sensor (LVIS), which confers decimeter-scale vertical resolution. We validate LVIS observations using matchup observations from AVIRIS-NG imagery to test whether LiDAR remote sensing can improve monitoring of emergent kelps in key biodiversity regions such as the Western Cape.

Vertical structure of the aquatic light field based on half a century of oceanographic records from the southern California Current
Brayden Lipscomb, West Virginia University
Understanding the optical properties of marine ecosystems is crucial for improving models related to oceanic productivity. Models relating satellite observations to oceanic productivity or subsurface (e.g., benthic) light availability often suffer from uncertainties in parameterizing vertical structure and deriving columnar parameters from surface observations. The most accurate models use in situ station data, minimizing assumptions such as atmospheric optical thickness or water column structure. For example, improved accuracy of satellite primary productivity models has previously been demonstrated by incorporating information on vertical structure obtained from gliders and floats. We analyze vertical profiles in photosynthetically available radiation (PAR) obtained during routine surveys of the southern California Current system by the California Cooperative Oceanic Fisheries Investigation (CalCOFI). We find that depths of 1% and 10% light availability show coherent log-linear relationships with attenuation measured near surface (i.e., within the first 10 m), despite vertical variability in water column constituent concentrations and instrumentation challenges related to sensitivity, self-shading, and ship adjacency. Our results suggest that subsurface optical properties can be more reliably parameterized from near-surface measurements than previously understood.

Comparing SWOT and PACE Satellite Observations to Assess Modification of Phytoplankton Biomass and Assemblage by North Atlantic Ocean Eddies
Dominic Bentley, Pennsylvania State University
Upwelling is the shoaling of the nutricline, thermocline, and isopycnals due to advection by eddies of the surface ocean layer. This shoaling effect leads to an increase in the productivity of algal blooms in a given body of water. Mesoscale to deformation scale eddy circulation modulates productivity based on latitude, season, direction, and other physical factors. However, many processes governing the effects of eddies on the ocean microbial environment remain unknown due to limitations in observations linking eddy strength and direction with productivity and ocean biogeochemistry. Currently, satellites are the only ocean observing system that allows for broad spatial coverage with high resample rates, albeit with limitations due to cloud obstructions (including storms that may stimulate productivity) and to observations being limited to the near-surface. A persisting knowledge gap in oceanography stems from limitations in the spatial resolution of observations resolving submesoscale dynamics. The recent launch of the Surface Water and Ocean Topography (SWOT) mission in December of 2022 supports observations of upper-ocean circulation with increased resolution relative to legacy missions (e.g. TOPEX/Poseidon, Jason-1, OSTM/Jason-2). Meanwhile, the launch of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite in February of 2024 is anticipated to improve knowledge of ocean microbial ecosystem dynamics. We match up SWOT observations of sea surface height (SSH) anomalies—informative parameters of eddy vorticity—with PACE observations of surface phytoplankton biomass and community composition to relate the distribution of phytoplankton biomass and assemblage structure to oceanic eddies in the North Atlantic. We observe higher concentrations of Chlorophyll a (Chla) within SSH minima indicating the stimulation of phytoplankton productivity by cyclonic features associated with upwelling-driven nutrient inputs.

Assessing EMIT observations of harmful algae in the Salton Sea
Abigail Heiser, University of Wisconsin- Madison
In 1905, flooding from the Colorado River gave rise to what would become California’s largest lake, the Salton Sea. Today, the majority of its inflow is sourced from agricultural runoff, which is rich in fertilizers and pollutants, leading to elevated lake nutrient levels that fuel harmful algal blooms (HAB) events. Increasingly frequent HAB events pose ecological, environmental, economic, and health risks to the region by degrading water quality and introducing environmental toxins. Using NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) imaging spectrometer we apply two hyperspectral aquatic remote sensing algorithms; cyanobacteria index (CI) and scattering line height (SLH). These algorithms detect and characterize spatiotemporal variability of cyanobacteria, a key HAB taxa. Originally designed to study atmospheric mineral dust, EMIT’s data products provide novel opportunities for detailed aquatic characterizations with both high spatial and high spectral resolution. Adding aquatic capabilities for EMIT would introduce a novel and cost-effective tool for monitoring and studying the drivers and timing of HAB onset, to improve our understanding of environmental dynamics.

Reassessing multidecadal trends in Water Clarity for the central and southern California Current System
Emma Iacono, North Carolina State University
Over the past several decades, the world has witnessed a steady rise in average global temperatures, a clear indication of the escalating effects of climate change. In 1990, Andrew Bakun hypothesized that unequal warming of sea and land surface temperatures would increase pressure gradients and lead to rising rates of alongshore upwelling within Eastern Boundary Currents, including the California Current System (CCS). An anticipated increase in upwelling-favorable winds would have profound implications for the productivity of the CCS, wherein upwelled waters supply nutrient injections that sustain and fuel coastal ocean phytoplankton stocks. Increasing upwelling, therefore, is anticipated to increase the turbidity of the upper ocean, corresponding with greater phytoplankton concentrations. Historical observations of turbidity are supported by observations obtained using a Secchi Disk, i.e., an opaque white instrument lowered into the water column. Observations of Secchi depth—or the depth at which light reflected from the Secchi Disk is no longer visible from the surface—provide a quantification of light penetration into the euphotic zone. The shoaling, or shallowing, of Secchi disk depths was previously reported for inshore, transition, and offshore waters of the central and southern CCS for historical observations spanning 1969 – 2007. Here, we reassess Secchi disk depths during the subsequent period spanning 2007 to 2021 and test for more recent changes in water clarity. Additionally, we evaluate the seasonality and spatial patterns of Secchi disk trends to test for potential changes to oceanic microbial ecology. Indications of long-term trends in some of the coastal domains assessed were found. Generally, our findings suggest a reversal of the trends previously reported. In particular, increases in water clarity likely associated with a recent marine heatwave (MHW) may be responsible for recent changes in Secchi disk depth observations, illustrating the importance of MHW events for modifying the CCS microbial ecosystem.

Perseverance Kicks off the Crater Rim Campaign!
Mastcam-Z mosaic made of 59 individual Mastcam-Z images showing the area Perseverance will climb in the coming weeks on its way to Dox Castle, the rover’s first stop on the crater rim. NASA/JPL-Caltech/ASU/MSSS Perseverance is officially headed into a new phase of scientific investigation on the Jezero Crater rim!
For the last 2 months, the Perseverance rover has been exploring the Neretva Vallis region of Jezero Crater, where rocks with interesting popcorn-like textures and “leopard spot” patterns have fascinated us all. Now, the rover has begun its long ascent up the crater rim, and is officially kicking off a new phase of exploration for the mission.
Strategic (longer-term) planning is particularly important for the Mars 2020 mission given the crucial role Perseverance plays in collecting samples for Mars Sample Return, and the Mars 2020 team undertakes this planning in the form of campaigns. Perseverance has now completed four such campaigns— the Crater Floor, Delta Front, Upper Fan and Margin Unit campaigns respectively— making the Crater Rim Campaign next in line. Given its broad scope and the wide diversity of rocks we expect to encounter and sample along the way, it may be the most ambitious campaign the team has attempted so far.
The team also has less information from orbiter data to go on compared to previous campaigns, because this area of the crater rim does not have the high-resolution, hyperspectral imaging of CRISM that helped inform much of our geological unit distinctions inside the crater. This means that Mastcam-Z multispectral and SuperCam long-distance imaging will be particularly useful for understanding broadscale mineralogical distinctions between rocks as we traverse the crater rim. Such imaging has already proved extremely useful in the Neretva Vallis area, where at Alsap Butte we observed rocks that appeared similar to each other in initial imaging, but actually display an Andy-Warhol-esque array of color in multispectral products, indicative of varied mineral signatures.
Our next stop is Dox Castle where Perseverance will investigate the contact between the Margin Unit and the Crater rim, as well as rubbly material that may be our first encounter with deposits generated during the impact that created Jezero crater itself. Later in the campaign, we will investigate other light-toned outcrops that may or may not be similar to those encountered at Bright Angel, as well as rocks thought to be part of the regionally extensive olivine-carbonate-bearing unit, and whose relationship to both Séítah and the Margin Unit remains an interesting story to unravel. Throughout this next phase of exploration, comparing and contrasting the rocks we see on the rim to both each other and those previously explored in the mission will be an important part of our scientific investigations.
The whole Mars 2020 science team is incredibly excited to be embarking on the next phase of Perseverance’s adventure, and we expect these results, and the samples we collect along the way, to inform our understanding of not just Jezero itself, but the planet Mars as a whole. We can’t wait to share what we find!

On Aug. 10, 1969, Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin completed their 21-day quarantine after returning from the Moon. The historic nature of their mission resulted in a very busy postflight schedule for Armstrong, Collins, and Aldrin, starting with celebrations in New York, Chicago, Los Angeles, and Houston. Scientists continued to examine the lunar samples the Apollo 11 astronauts returned from the Sea of Tranquility. NASA set its sights on additional lunar landing missions, announcing plans for a pinpoint landing by Apollo 12 in November 1969 that also included visiting the robotic Surveyor 3 that landed on the Moon in 1967. The agency announced the crews for the Apollo 13 and 14 missions planned for 1970. Including prime and backup crews, NASA had 18 astronauts training for lunar landing missions. Support astronauts brought that number to 32.
Apollo 11
Following their return from the Moon, Armstrong, Collins, and Aldrin completed their 21-day quarantine in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. During their stay in the LRL, they worked on their pilot reports, conducted postflight debriefs including with the Apollo 12 crew, and Armstrong celebrated his 39th birthday. On the evening of Aug. 10, they left the relative quiet of the LRL for a very hectic next few months. After spending a day reuniting with their families, the three reported back to their offices and held their postflight press conference on Aug. 12. The next day, they flew first to New York for a massive ticker tape parade, then on to Chicago for another big parade, ending the day in Los Angeles with a state dinner hosted by President Richard M. Nixon and attended by most active astronauts, members of Congress, 44 state governors, and 83 foreign ambassadors. They returned to Houston for a welcome home parade on Aug. 16, ending the day with a barbecue party and a tribute to the entire NASA team in the Astrodome, emceed by Frank Sinatra. Meanwhile, on Aug. 14, engineers shipped the Command Module Columbia to its manufacturer, the North American Rockwell plant in Downey, California, for postflight inspections. Scientists in the LRL eagerly continued their examinations of the 48 pounds of lunar material the Apollo 11 astronauts returned from the Sea of Tranquility.

“It was our pleasure to participate in one great adventure. It’s an adventure that took place, not just in the month of July, but rather one that took place in the last decade. We … had the opportunity to share that adventure over its developing and unfolding in the past months and years. It’s our privilege today to share with you some of the details of that final month of July that was certainly the highlight, for the three of us, of that decade.”

Apollo 12
At the time Apollo 11 returned from its historic journey, NASA had plans for nine more Apollo Moon landing missions. On July 29, Apollo Program Director Samuel C. Phillips at NASA Headquarters in Washington, D.C., announced the launch date, Nov. 14, 1969, and the landing site, in the Ocean of Storms, for Apollo 12. The main goals of this second lunar landing included a precision touchdown near the Surveyor 3 spacecraft that landed there in April 1967, and an expanded science program conducted during two spacewalks, including the deployment of the first Apollo Lunar Surface Experiment Package (ALSEP), a suite of science instruments. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, Command Module Pilot (CMP) Richard F. Gordon, and Lunar Module Pilot (LMP) Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin, began training after their assignment in April. In addition to rehearsing aspects of their flight in mission simulators, they practiced for the descent and precision landing, for the two spacewalks planned during their 31.5-hour lunar surface stay, including visiting and examining Surveyor 3, and for the expanded geology exploration. The latter included a three-day geology field trip to Hawaii with simulated lunar traverses. At NASA’s Jet Propulsion Laboratory in Pasadena, California, the astronauts received a detailed briefing on the Surveyor spacecraft. At NASA’s Kennedy Space Center (KSC) in Florida, workers had already assembled their Saturn V rocket, with rollout to Launch Pad 39A planned for early September. The U.S. Navy chose the U.S.S. Hornet (CVS-12), the carrier that successfully recovered Apollo 11, to reprise its role as prime recovery ship for Apollo 12.

Apollo 13 and 14
On Aug. 6, 1969, NASA announced the crews for Apollo 13 and 14, the third and fourth Moon landing missions. At the time of the announcement, Apollo 13 had a planned launch date in March 1970 and a proposed landing site at the Fra Mauro region in the lunar highlands, the first landing site not in the relatively flat lunar maria. Apollo 14 aimed for a July 1970 mission with the Crater Censorinus area in the lunar highlands to the southeast of the Sea of Tranquility as a tentative landing site. Plans for both missions called for two lunar surface excursions totaling about six hours with a lunar stay duration of 35 hours. As on Apollo 12, the crews planned to deploy an ALSEP suite of science instruments, in addition to conducting the geology field work of documenting and collecting rock and soil samples for return to scientists on Earth for analysis.

The prime crew for Apollo 13 consisted of Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise. Lovell would make his fourth space mission aboard Apollo 13, having flown on Gemini VII and XII as well as orbiting the Moon during Apollo 8 – making him the first person to travel to the Moon twice. Neither Mattingly nor Haise had flown in space before, although Haise had served with Lovell on the Apollo 11 backup crew. The Apollo 13 backup crew consisted of John W. Young, John L. Swigert, and Charles M. Duke. Young had flown three previous missions, Gemini 3 and X and more recently aboard Apollo 10, the Moon landing dress rehearsal flight. Swigert and Duke had no spaceflight experience, although Duke served as capsule communicator during Apollo 10 as well as during the Apollo 11 Moon landing.

Flight hardware for Apollo 13 had already arrived at KSC. Workers in the Vehicle Assembly Building (VAB) completed stacking of the three Saturn V rocket stages in High Bay 2 on July 31. They added a boilerplate Apollo spacecraft to the top of the rocket, and in a roll-around maneuver on Aug. 8, the stack left the VAB, crawled to the other side of the building, and rolled back inside to High Bay 1. North American Rockwell delivered the Command and Service Modules to KSC on June 26, where workers in the Manned Spacecraft Operations Building (MSOB) mated the two modules four days later in preparation for preflight testing in altitude chambers. The Lunar Module (LM) ascent and descent stages arrived at KSC on June 27 and 28, respectively, from their manufacturer, the Grumman Aircraft Corporation in Bethpage, New York. Following a docking test between the CM and LM, workers in the MSOB mated the two stages of the LM on July 15.
The Apollo 14 crew of Alan B. Shepard, left, Stuart A. Roosa, and Edgar D. Mitchell.
NASA designated Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell as the prime crew for Apollo 14. Shepard, the first American in space when he launched aboard his Freedom 7 spacecraft in May 1961, recently returned to flight status after a surgical intervention cured his Ménière’s disease, an inner ear disorder. Neither Roosa nor Mitchell had spaceflight experience. The backup crew consisted of Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle. Cernan had flown in space twice before, on Gemini IX and more recently on Apollo 10. Evans and Engle had not flown in space before, although Engle earned astronaut wings as a pilot with the U.S. Air Force flying the X-15 rocket plane above the 50-mile altitude required to qualify as an astronaut on three of his 16 flights.

The Apollo 14 astronauts jumped right into their geology training. On Aug. 14, Shepard, Mitchell, and Engle spent the day at the United States Geological Service’s (USGS) Crater Field near Flagstaff, Arizona, including getting a geologist’s lecture on the mechanisms of crater formation. On Aug. 22 and 23, Cernan joined them on a geology field trip to Idaho, where they visited Craters of the Moon National Monument, Butte Crater lava tubes, Ammon pumice quarries, and the Wapi volcanic fields. Geologists chose these sites for training because at the time Apollo 14 planned to visit a presumed volcanic area on the Moon.

Several changes in senior NASA leadership took place following Apollo 11. At NASA Headquarters in Washington, D.C., Phillips retired as Apollo Program Director, having served in that position since 1964, and returned to the U.S. Air Force. Rocco A. Petrone, director of launch operations at KSC since 1966, succeeded him. George S. Trimble announced his retirement as MSC deputy director effective Sept. 30, having served in that role since October 1967. In November 1969, MSC Director Robert R. Gilruth named Christopher C. Kraft to succeed Trimble as his deputy.
