Which nutrient transport pattern does Ekman transport establish along eastern boundary currents where gyres rotate?

💡 Explanation

When wind stress acts along eastern boundaries, Ekman transport causes offshore surface water movement which induces upwelling because deeper, nutrient-rich water replaces the surface water. Therefore coastal upwelling and enrichment results, rather than reduction of density stratification, thermocline or salinity wedge expansion, whose formation relies on separate stratification mechanisms.
