The Corner Rise Seamounts are a chain of extinct submarine volcanoes in the northern Atlantic Ocean east of the New England Seamounts. Both it and the New England Seamounts were formed by the Great Meteor hotspot.[1] It is the shallowest seamount in New England, with some of its nineteen highest peaks only 800–900 m deep.[2]

Like most seamounts, they attract fish. Over 175 species have been found there,[1] including splendid alfonsino, black cardinal fish, black scabbardfish, and wreckfish.[2] Trawl fishing during the 1970s and 1980s resulted in approximately 20,000 tons of fish being harvested.[1] As a result, the seamounts were closed to demersal fishing (collecting fish near the bottom of the ocean, as opposed to pelagic fishing, collecting fish near the surface) beginning 1 January 1997. The original ban was supposed to be lifted 31 December 2010,[1] but was extended until 31 December 2020.[2] Almost a decade into the ban, a 2005 Woods Hole Oceanographic Institution survey found that two of the peaks, Kükenthal and Yakutat, had been stripped bare of both corals and bottom-dwelling animals.[3][4] However the survey, which covered both the Corner Rise and New England Seamounts, found 270 species of invertebrates and crustaceans, including 70 species unique to the Corner Rise Seamounts.[5]
