Which effect intensifies when geostrophic flow encounters coastal upwelling?

💡 Explanation

Coastal upwelling draws deep, nutrient-rich water up, and geostrophic flow enhances the localized **Ekman transport** that drives upper ocean layer motion; therefore, nutrient concentration dramatically increases, rather than a weaker stratification, because of additional flow, and not simply initial stratification.
