The barrow submarine canyon: A drain for the Chukchi Sea

Abstract

Oceanographic measurements made in the spring through holes in the ice in an area off Barrow, where the Barrow Canyon forms a sloping trough from the shallow Chukchi Sea into the deep Beaufort Sea, have revealed two interacting water movements: (1) a flow of highly saline water from the shallow Chukchi Sea into the Beaufort Sea through the Barrow Canyon and (2) an uprising of Atlantic water from the depths of the Beapfort Sea into the Barrow Canyon.
