National Geographic is adding the hour-long TV special, Expedition: Saving Our Seas, that will premiere on Monday, 16 November on National Geographic (DStv 181) and will stream on Disney+ and explore all 5 of the world's ocean basins.
Produced by Offspring Films, Expedition: Saving Our Seas has Auli'i Cravalho as narrator.
The documentary follows teams of National Geographic Explorers as they investigate our global ocean, from seashore to seafloor.
Viewers get to see the ocean's depths through remotely operated vehicle SuBastian aboard the Schmidt Ocean Institute's research vessel Falkor in the Southern Ocean, including oceanographer Dr Andrew Thurber, biological oceanographer Dr Kim Bernard and microbial oceanographer Dr Allison Fong as they survey the basin's depths and its icy surface.
Tracking blue whales and their krill prey, Dr Bernard returns alongside Explorer and marine ecologist Dr Leigh Torres and the local Māori community to New Zealand's South Taranaki Bight.
Explorer Dr Anya Brown studies coral for heat tolerance in the Cook Islands. Both teams are racing to understand how rising temperatures are reshaping Pacific Ocean ecosystems.
Meanwhile, deep below the Indian Ocean's surface, the first deep-sea scientist from the Seychelles, Explorer Sheena Talma, and her Seychellois team are getting training on deep-ocean camera lander systems off the coast of South Africa.
They will deploy similar landers in the Seychelles to gather data to support fisheries and marine protected area management.
Along the Gambian coastline, coastal researcher, marine ecologist and Explorer Maiyai Taal Hocheimy trains local students to measure ocean depth and currents and works with Explorer Dr Angelo Bernardino to map and assess the mangrove forests standing between the capital, Banjul, and the encroaching water.
In the Arctic Ocean, warming at four times the rate as the rest of the planet, marine biogeochemist Dr Kristina Brown conducts the first-known scientific study of a secluded marine bay called the Sherman Basin to chart a seafloor no one has ever seen.
Then there is Dr Katy Croff Bell, founder of the Ocean Discovery League, who is developing a Deep Ocean Research and Imaging System (DORIS) as a lightweight, low-cost device designed to open up deep-sea exploration to communities that have not previously had access to their deep-ocean waters.
Expedition: Saving Our Seas is directed by Katharine Arthy and executive produced by Sam Hodgson for Offspring Films, Vanessa Serrao and Kaitlin Yarnall for National Geographic Society, and Tracy Rudolph Jackson for National Geographic.
