Which mechanism increases primary productivity in coastal regions when winds drive surface waters offshore?

💡 Explanation

When surface waters move offshore due to wind, upwelling occurs because deep, nutrient-rich water rises to replace the displaced surface water, boosting phytoplankton growth. Therefore, increased primary productivity results, rather than irradiance absorption, nitrogen fixation, or sediment settling, which depend on other circumstances.
