Scientists peer through the lens of the Jason II remotely operated vehicle at 2,500 meter depth near the DeSoto Canyon. Submarine canyons are steep-sided features that cut through the continental slope. At this site, an exposed rock bed juts from the abyssal plain, providing substrate for bamboo and black corals, a chemosynthetic mussel community, and a deep-sea octopus. This was the deepest dive of Lophelia II 2009 at 2,500 m (8,200 ft) depth.
