Which biogeochemical effect typically follows enhanced coastal upwelling along continental margins?

💡 Explanation

When upwelling increases, nutrient-rich deep water is brought to the surface because of wind-driven transport and Coriolis effect, fueling phytoplankton growth which supports the marine food web. Therefore, a phytoplankton bloom results, rather than eutrophication, acidification, or decreased nutrients, which counteract upwelling’s effects.
