Eddies of the Western Arctic Ocean - Their Characteristics and Importance to the Energy, Heat, and Salt Balance.
With the undertaking of the main 1975-76 AIDJEX experiment located in the central Beaufort Sea, four manned camps collected for one year the largest and most complete set of oceanographic data within the Arctic Ocean to this date. During this time, a total of 146 separate crossings of eddies were ob...
