Which mechanism primarily deflects geostrophic currents into coastal boundary currents along continental margins?

💡 Explanation

When wind blows along a coastline, Ekman transport causes surface water to move offshore, increasing density gradients. This generates geostrophic currents due to Coriolis force leading to coastal boundary currents. Therefore Ekman transport results, rather than mechanisms from thermocline, coriolis alone, or tidal resonance.
