7 Min Read NASA Project in Puerto Rico Trains Students in Marine Biology
A forested green peninsula of Culebra Island juts into the blue waters of the Caribbean as a rain storm hits in the distance. The teal blue surrounding the island indicates shallow waters, home to the island's famous coral reefs. Credits: NASA Ames/Milan Loiacono Tainaliz Marie Rodríguez Lugo took a deep breath, adjusted her snorkel mask, and plunged into the ocean, fins first. Three weeks earlier, Rodríguez Lugo couldn’t swim. Now the college student was gathering data on water quality and coral reefs for a NASA-led marine biology project in Puerto Rico, where she lives.
“There is so much life down there that I never knew about,” Rodríguez Lugo said. “And it’s beautiful.”

OCEANOS 2024 Intern
The sea whip and purple sea fans in the photo above are found off the coast of Playa Melones, Culebra, a small island off the east cost of Puerto Rico and a popular destination for snorkelers.
Puerto Rico is home to more than 1,300 square miles of coral reefs, which play a vital role in protecting the island from storms, waves, and hurricanes. Reef-related tourism provides nearly $2 billion in annual income for the island.
But coral reefs in Puerto Rico and around the world are experiencing more frequent and severe bleaching events. High ocean temperatures in regions around the globe have led to coral bleaching, which is when corals expel zooxanthellae – the colorful, symbiotic microscopic algae that live inside coral tissues and provide 80-90% of its nutrients. When stressors persist, the corals eventually starve and turn bone-white.
In April 2024, NOAA (National Oceanic and Atmospheric Administration) announced that the world was experiencing a global bleaching event, the fourth on record. You can see bleached spots in the lobed star coral pictured above, which is also colonized by Ramicrusta, an invasive, burnt orange algae that poses an additional threat to reefs.
Students Are Given Ocean Research Tools
Beginning in June, the month-long program that Rodriguez and 29 other local students participated in is called the Ocean Community Engagement and Awareness using NASA Earth Observations and Science for Hispanic/Latino Students (OCEANOS). The goal of OCEANOS is twofold: to teach Puerto Rican students about marine ecology and conservation, and to train students through hands-on fieldwork how to use marine science tools to monitor the health of coral reefs.
The course included classroom instruction, scientific fieldwork, collecting and analyzing ocean data from La Parguera and Culebra Island, and a final presentation.
In the photo, OCEANOS instructor Samuel Suleiman shows a 3D-printed clump of staghorn coral to a group of students off the coast of Culebra. In areas where coral habitats have been damaged, conservationists use 3D-printed corals to attract and protect fish, algae, and other wildlife.
To practice coral surveying techniques and evaluate biodiversity,students used compact cameras to snap a photo every half second, recording seven-meter by seven-meter quadrants of the ocean floor. Back on land, the students stitched these images – roughly 600 images per quadrant – into high-resolution mosaics, which they then used to catalog the types and distributions of various coral species.
Low Light, Poor Water Quality, and Invasive Species Threaten Coral Reefs
Students also built their own low-cost instruments, with sensors on each end to measure temperature and light, to help assess water quality and characteristics.
The ideal temperature range for coral falls between 77- 82 degrees Fahrenheit (25-28 degrees Celsius). Water above or below this range is considered a potential stressor for coral and can impair growth. It can also increase the risk of disease, bleaching, and reproductive issues.
Coral relies on light for growth. Less light means less photosynthesis for the zooxanthellae that live inside the coral, which in turn means less food for the coral itself. Cloudy water due to excessive sediment or phytoplankton can dim or block sunlight.
Additional threats to coral include fishing equipment, boat groundings, chemical runoff, and invasive species.
In the photo above, OCEANOS instructor Juan Torres-Pérez holds two clumps of cyanobacteria, a type of bacteria that has choked a section of reef near Playa Melones. The exact cause of this excessive cyanobacteria growth is unclear, but it is likely due to land-based pollution leaching into nearby waters, he said. In the background, dark brown piles of cyanobacteria littering the ocean floor are visible.
Students Help Grow and Plant New Coral
Suleiman walked students through the process of planting new coral, which involved tying loose staghorn and elkhorn corals into a square frame. Each frame holds about 100 individual pieces of coral. Suleiman leads a group called Sociedad Ambiente Marino (SAM), which has been working for more than 20 years to cultivate and plant more than 160,000 corals around Puerto Rico.
Divers anchored these frames to the ocean floor. Under ideal conditions, branching species like elkhorn and staghorn coral grow one centimeter per month, or about 12-13 centimeters per year, making them ideal candidates for coral reef restoration. By comparison, mountainous and boulder coral, also prevalent in the Caribbean Sea, grow an average of just one centimeter per year.
The frames will remain on the ocean floor for 10 to 14 months, until the corals have quadrupled in size. At any given time, SAM has about 45 of these frames in coral ‘farms’ around Culebra, totaling almost 4,500 corals.
Once the corals are ready to be planted, they will be added to various reefs to replace damaged or bleached corals, and shore up vulnerable habitats.
In the photo above, Suleiman gathers loose corals to place around an endangered coral species Dendrogyra cylindrus, more commonly referred to as Pillar Coral (front left). This underwater “garden,” as he called it, should attract fish and wildlife such as sea urchins, which will give the endangered coral — and the other species in this small reef — a better chance of survival.
A New Generation of Marine Scientists
From the 2023 OCEANOS class, roughly half of the undergraduate students went on to pursue marine science degrees, and many hope to continue with a post-graduate program. For a scientific field historically lacking diverse voices, this is a promising step.
Among the high school students in the 2023 class, three went on to change their degree plans to oceanography after participating in the OCEANOS program, while others are finding ways to incorporate marine science into their studies.
Francisco Méndez Negrón, a 2023 OCEANOS graduate, is now a computer science student at the University of Puerto Rico at Rio Piedras and wants to apply robotics to marine ecology. “My goal is to integrate computer science and oceanography to make something that can contribute to the problems marine ecosystems are facing, mostly originated by us humans,” Méndez Negrón said. He returned to the OCEANOS program to serve as a mentor for the 2024 class.
As for Tainaliz Marie Rodriguez Lugo, she managed to overcome her swim anxiety while discovering a love of the ocean. She credited the instructors who were patient, encouraging, and never left her side in the water.
“I was really scared going into this internship,” Rodríguez Lugo said. “I didn’t know how to swim, and I was starting a program literally called ‘Oceans.’ But now I love it: I could spend all day in the ocean.”

When asked how she would describe coral to someone who has never seen one, Rodríguez Lugo just laughed. “I can’t. There are no words for it. I would just take them to the reefs.”

Isn't it striking that these days we hear new revelations almost daily about UFOs and non-human beings that have been witnessed by civilians and the military, like the former intelligence official who claimed that the U.S. has retrieved craft of non-human origin and the bizarre story of a Las Vegas family who claimed that they saw aliens after something crashed in their backyard.
Yet, just two days later again two new amazing stories; of a former Marine who witnessed a hovering octagonal UFO being loaded with weapons by unmarked US forces in Indonesia and military individuals who claim that not only the US has a secret UFO retrieval program but that 12 or more non human space craft in custody of the U S Government.
Regardless of whether all these confessions are true or false, the question is for how long the Government as well as the Cabal can keep secret the existence of their own UFO program and the existence of non human craft. The larger and more complex a program is, the more difficult it becomes to keep it a secret. If the UFO program involves a significant number of individuals, resources, and facilities, the chances of leaks or disclosures increase.
At first there is the former Marine, Michael Herrera, who has recently broken a 14-year silence to make an astonishing claim about an incident that allegedly took place during his service in Indonesia in 2009. According to Herrera, he and his five comrades witnessed a hovering octagonal UFO being loaded with weapons by unmarked US forces. He further alleges that they were threatened at gunpoint by these unidentified personnel.
Herrera, who was 20 years old at the time, was deployed on a Navy humanitarian mission following the Sumatra earthquake and tsunami. In an interview with DailyMail.com, he describes how his six-man unit encountered the mysterious craft while guarding an airdrop of aid supplies outside the city of Padang in October 2009.
Herrera said that the UFO was rotating in a clockwise motion, changing colors, and emitting an audible hum resembling that of a transformer or a guitar amp. It had an octagonal shape with a black pyramid at the top.
And second, it seems as there are 12 or more non human space craft in custody of the U S Government.
According to sott.net, this is not the first time government officials have suggested that the U.S. may possess alien spaceships. "I was told for decades that Lockheed had some of these retrieved materials," said the late Senator Harry Reid, who fought for greater disclosure.
Former deputy assistant secretary of Defense for Intelligence, Christopher Mellon, recently reported that he has spoken to more than four witnesses who say they know of "a secret U.S. government program involving the analysis and exploitation of materials recovered from off-world craft.
The individuals said they had seen or been presented with "credible" and "verifiable" evidence that the U.S. government, and U.S. military contractors, possess at least 12 or more alien space crafts, some of which they shared with AARO, which AARO has refused to provide to Congress.
Some of the same sources who shared information with former intelligence official Grusch, as well as others, spoke to public about retrieved spacecraft that they say is in the possession of the U.S. government. "I know of at least 12-15 craft and every five years, we get one or two recovered for one reason or another, from either a landing or that we catch, or they just crash." said one person.

Many parts of Europe saw record-breaking temperatures over the summer, but it wasn’t just the continental mainland that was affected: the Mediterranean Sea also suffered a major marine heatwave. An ESA-funded project, CAREHeat, detected one of the most intense Mediterranean marine heatwaves observed during the satellite era – with sea surface temperatures reaching 5°C higher than average.

Every 60 seconds the equivalent of a lorry-load of plastic enters the global ocean. Where does it end up? Right now, researchers simply don’t know. But in a bid to help find out, an ESA-led project developed floating transmitters whose passage can be tracked over time, helping in turn to guide a sophisticated software model of marine plastic litter accumulation.
