Trinidad and Tobago's deep-sea expedition is the headline story on this episode of Ocean Decoded Live, and host Andrew Lewin breaks down what a mostly Trinbagonian science team found during the first-ever locally led deep-sea survey in the country's history. Led by marine biologist Dr. Diva Amon, the team mapped 13% of the nation's previously uncharted seafloor and came back with at least 20 suspected new species, 25 active cold-seep ecosystems, a rare manta ray fall caught on camera, and a decade-old octopus mystery finally confirmed after Amon first spotted the animal on an expedition back in 2014. Amid all the discovery, the team also found evidence of human-made trash on the seafloor, a reminder that no part of the ocean is truly untouched anymore.
From there, the show turns to today's Ocean People Profile on Dr. Nathan Robinson, the marine biologist whose viral videos, pulling a plastic straw and later a plastic fork from sea turtles' noses, helped ignite the global anti-plastic-straw movement, and who has spent his career since turning that unplanned spotlight into a research strategy built around cameras, drones, and now AI and machine learning. The episode closes with beluga whale deaths at Chicago's Shedd Aquarium, where three belugas, Peekachu, Rain, and Beethoven, died in just eight days. Two had just arrived as part of an unprecedented international rescue of 30 belugas from the shuttered Marineland of Canada, but Beethoven was a healthy longtime Shedd resident with no connection to the transfer, and that detail is driving outside experts to raise the possibility of a transferred pathogen or transfer-related stress while necropsies remain underway.
Takeaways:
A Trinidad and Tobago-led deep-sea expedition, headed by Dr. Diva Amon, mapped 13% of the country's uncharted seafloor and found at least 20 suspected new species and 25 active cold-seep ecosystems.
The expedition also confirmed a Graneledone octopus first spotted in 2014 as a likely new species, and documented a rare manta ray fall at 1,025 meters, alongside evidence of human-made trash on the seafloor.
Today's Ocean People Profile covers Dr. Nathan Robinson, known for viral videos removing plastic from sea turtles' noses, whose recent published research has shifted toward AI, machine learning, and animal-welfare studies of his own research tools.
Three beluga whales died at Shedd Aquarium in Chicago within eight days; two were recent arrivals from the shuttered Marineland of Canada, but the third, Beethoven, was a healthy longtime resident, raising questions about possible contamination or transfer-related stress.
Necropsies are underway, and Shedd is comparing notes with the four other facilities (Georgia Aquarium, SeaWorld San Antonio, SeaWorld San Diego, and Oceanogràfic València) that also took in Marineland belugas.
