DNA analysis recently confirmed that Woods Hole Oceanographic Institution (WHOI) scientists and their collaborators at OceanX, the University of Connecticut (UConn), and NASA’s Jet Propulsion Laboratory (JPL) discovered two new species of deep-sea corals during a September 2018 expedition in the Northeast Canyons and Seamounts National Monument, located about 100 miles from the Northeast U.S. coast.
The research team was led by deep-sea biologist Tim Shank of WHOI and included co-PIs Taylor Heyl (WHOI), Rachel O’Neill (UConn), and John Leichty (JPL). Utilizing OceanX’s research and exploration vessel Alucia, the team explored and surveyed several of the unique deep-sea habitats in the monument, which includes three underwater canyons deeper than the Grand Canyon.
During the two-week expedition, the scientists collected a total of 29 coral samples in Lydonia Canyon at depths between 369 meters (1,211 feet) and 903 meters (2,963 feet) using the submarine Nadir. These were the first human-occupied submersible dives in this canyon since 1982 and only the third deep-submergence mission to Lydonia Canyon.
