Which phenomenon causes increased marine productivity along coastlines with offshore winds?

💡 Explanation

When offshore winds blow along a coastline, Ekman transport occurs because the Coriolis effect deflects the surface water layer, resulting in net transport of water away from the coast and upwelling of nutrient-rich deeper water. Therefore, upwelling results, rather than overturning, current accumulation, or tidal amplification, each driven by different mechanisms.
