Which mechanism causes higher chlorophyll concentrations along coastlines in coastal regions?

💡 Explanation

When wind blows parallel to a coastline, Ekman transport causes the surface layer to move offshore, inducing upwelling because this offshore movement leads to a vertical replacement of water masses, bringing nutrient-rich deep water to surface. Therefore upwelling causes increases in chlorophyll rather than runoff, deposition, or mixing which have differing primary mechanisms.
