Expedition: Saving Our Seas reveals deep-sea wonders Multiyear research study to document rapid environmental change "It's not the time to give up." In Expedition: Saving Our Seas, the National Geographic and Rolex Perpetual Planet Ocean Expeditions are on full display. The multiyear scientific research study involves a deep dive into the entirety of Earth's ocean. The informative documentary special utilizes groups of experts studying various aspects of the ocean. In the Southern Ocean, oceanographer Dr. Andrew Thurber, biological oceanographer Dr. Kim Bernard, and microbial oceanographer Dr. Allison Fong make groundbreaking discoveries, including the first known live sighting of a giant Antarctic gonate squid, 13,000 feet below the surface, using a remotely operated vehicle, SuBastian. In the Pacific Ocean, Dr. Bernard and Dr. Leigh Torres track blue whales off New Zealand, while Dr. Anya Brown heads to the Cook Islands to study coral for heat tolerance, with an emphasis on how temperatures are changing ecosystems. In the Indian Ocean, deep-sea scientist Sheena Talma and her Seychellois team analyze deep-ocean habitats by training on camera lander systems. Off the Gambian coastline, explorers Maiyai Taal Hocheimy and Dr. Angelo Bernardino research the rising levels of the Atlantic Ocean and the potential danger they pose to the nearly 500,000 people living there. In the Arctic Ocean, marine biogeochemist Dr. Kristina Brown teams with Inuk elder Saul Aksalook Qirqniq (ᐊᒃᓴᓗᒃ) and the Inuit community of Gjoa Haven for the first known scientific study of the secluded marine bay called the Sherman Basin. “We’ve only seen about 0.001% of the deep ocean, which covers about two-thirds of our planet,” Dr. Katy Croff Bell, founder of the Ocean Discovery League, said in a press release. “Just imagine what we’re going to find in the other 99.999%.” Dr. Bell is developing an affordable lightweight device—Deep Ocean Research and Imaging System (DORIS)—to make deep-sea exploration accessible to communities that have never had access to these waters.
