Which effect increases phytoplankton concentration when coastal upwelling occurs?

💡 Explanation

When coastal upwelling occurs, nutrient-rich water rises from the ocean depths because prevailing winds drive surface water offshore, leading to replacement by deeper water. Therefore, nutrient transport increases phytoplankton concentrations rather than stratification.
