Ekman pumping induced by horizontally varying wind and sea ice drift is examined as an explanation for observed seasonal variation of the warm layer thickness of circumpolar deep water on the Amundsen Sea continental shelf. Spatial and temporal variation of the warm layer thickness in Dotson Trough was measured during two oceanographic surveys and a two-year mooring deployment. The observations were compared to time series of remotely sensed surface stress.
