Vertical structure and temporal variability of currents over the Chukchi Sea continental slope

Observations from a single mooring site on the northern Chukchi Sea continental slope near the 1000-m isobath are presented. This site was occupied consecutively for three years (spanning September 2014–August 2017). Vertically the flow divides into three depth ranges: the upper ~200 m, ~200–~850 m and near-bottom flow. In the upper ~200 m, the mean flow was northwestward and strongest in the summer months. During winter months, currents...
