Currents in the Aleutian Basin and subarctic North Pacific near the dateline in summer 1993

[1] The currents in the Aleutian Basin of the Bering Sea and in the subarctic North Pacific near the dateline in summer 1993 are described, based on Shipboard Acoustic Doppler Current Profiler and Lowered Acoustic Doppler Current Profiler velocity measurements and on conductivity-temperature-depth profiles. The strongest flow is the Alaskan Stream with velocities up to 90 cm s(-1) and with a subsurface core as narrow as 30 km at about 150 m depth. Velocity at the bottom below the Alaskan Stream could not be distinguished from zero. The inflow of the Alaskan Stream through Amchitka Pass accounted for about 70% of the Aleutian North Slope Current in the Aleutian Basin. Two anticyclonic eddies occupied most of the Aleutian Basin along the cruise track. Both eddies extended to the bottom.
