The Five Deeps Expedition (December 2018-August 2019): Victor Vescovo became the first human to descend to the deepest point in each of the Earth's five oceans—the Atlantic's Milwaukee Deep, the Southern's South Sandwich Trench, the Indian's Java Trench, the Pacific's Challenger Deep, & the Arctic's Molloy Deep—utilizing the D.S.V. Limiting Factor & the mothership D.S.S.V. Pressure Drop.
