Which phenomenon causes nutrient enrichment in surface waters during coastal upwelling?

💡 Explanation

When wind forces surface water offshore, Ekman transport occurs because of the Coriolis effect, resulting in the upwelling of cold, nutrient-rich water from the depths. Therefore nutrient enrichment results, rather than mixing, tidal effects or geothermal which have alternative causes.
