Which mechanism drives high coastal productivity from ocean depths?

💡 Explanation

As wind forces surface water offshore, upwelling occurs because the displacement forces deep, nutrient-rich waters upward; therefore algal booms occur near coasts due to upwelling enriching surface rather than caused by thermohaline forcing.
