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 Chukehi Sea into the deep Beaufort Sea, have revealed two interacting water movements: (1) a flow of highly saline water from the shallow Chukehi Sea into the Beaufort Sea through the Barrow Canyon and (2) an uprising of Atlantic water from the depths of the Beaufort Sea into the Barrow Canyon. |
