Which process strongly influences nutrient distribution within an ocean gyre's convergence zone?

💡 Explanation

When surface waters converge due to gyre circulation, Ekman transport causes downwelling because wind stress drives surface water towards the center, sinking and carrying nutrients away from the surface. Therefore, Ekman transport strongly diminishes surface nutrients, unlike resonance, vents or ice melt which do not describe localized dynamics.
