Which ocean phenomenon results when offshore winds drive surface waters away from a coastline?

💡 Explanation

When offshore winds displace surface waters, upwelling occurs because deep, nutrient-rich water rises to replace the surface water, fuelling primary production. Therefore, increasing marine productivity results, rather than gyre formation, erosion or circulation changes, which depend on other mechanisms.
