Which process causes nutrient upwelling on the eastern edge of ocean gyres contributing to high marine productivity?

💡 Explanation

When winds blow along the eastern boundaries, Ekman transport causes surface water to move offshore because the Coriolis effect deflects it, leading to upwelling of deeper, nutrient-rich water. Therefore Ekman transport causes gyre upwelling, rather than other mechanisms that lack that direct connection.
