Ekman transport is the net movement of water in the ocean due to the Coriolis effect. It is caused by the deflection of water at the surface of the ocean, which then causes water to move in a spiral pattern. The net effect of this spiral is a movement of water at a 90-degree angle to the direction of the wind.

The transport and mixing between the nearshore and offshore water masses have profound impacts on the water quality, primary production, and the pathway of marine pollutants in estuaries, bays, and continental shelves (Brink, 2016; Ding et al., 2016; Zhang et al., 2024).As such, the cross-isobath water exchange … mannington carpet corporate office

"Webb1 okt. 2024 · The Ekman transport of 90° would normally be offshore, regardless of hemisphere. The depth of frictional influence is only typically 50–200 m. Water from beneath this depth usually moves upward—upwelling—to replace the water that has been displaced farther offshore and is responsible for bringing nutrients back up to the surface.
