Plot Synopsis

EXPEDITION DEEP OCEAN is a five-part documentary series that follows the record-breaking mission of explorer and entrepreneur Victor Vescovo, and his Five Deeps Expedition team, made up of scientists and explorers as they set off on the first descent to the bottom of all five of the world's oceans. With Vescovo at the helm of his purpose-built Triton submarine, they take on the ground-breaking and at times dangerous mission to reach the bottom of the Atlantic, Pacific, Indian, Arctic, and the Southern Oceans, descending up to a record depth of 10,928 meters. The ship's team of scientists also discover over 40 extraordinary new species and scan areas of the oceans, which are less well-known than the surface of Mars. They brave seismic fault-zones as well as icebergs, and tropical storms in order to gather brand-new information from the bottom of the world. These are world-first missions across a nail-biting five hours, which create a new era of exploration into the deep ocean. On Thursday, April 1, 2021, discovery+ released all five 40-minute episodes of EXPEDITION DEEP OCEAN, with each episode focusing on a different ocean: Atlantic, Southern, Indian, Pacific, and Arctic. EXPEDITION DEEP OCEAN made its linear television debut on Sunday, January 2, 2022 from 9-11pm ET/PT, as Science Channel aired the first two episodes.
