Which mechanism drives upwelling along coastlines when Ekman transport moves surface water offshore?

💡 Explanation

When surface water moves offshore due to Ekman transport, density stratification overturn occurs because subsurface cold, nutrient-rich water rises to replace the displaced surface water, establishing vertical circulation. Therefore, density stratification overturn results, rather than the other options that don't directly induce vertical water movement to replace displaced surface water.
