Which effect is directly enhanced by increased upwelling along a coastline?

💡 Explanation

When upwelling increases, nutrient-rich deep water rises to the surface because wind-driven currents displace surface water, enhancing primary productivity. Therefore nutrient availability increases, rather than desertification, decreased acidity or thermal stratification, which require different oceanographic processes.
