Which process causes increased coastal upwelling on the eastern boundary of subtropical gyres?

💡 Explanation

When winds blow along the eastern gyre boundary, Ekman transport causes surface water to move offshore due to the Coriolis effect because of the wind stress, leading to upwelling. Therefore upwelling results rather than heating, subduction, or salinity changes which have different effects on coastal water dynamics.
