Which flow pattern arises when wind-driven surface currents converge toward the center of an ocean gyre?

💡 Explanation

When surface currents converge in a gyre's center, Ekman transport causes surface water to sink via downwelling because accumulating water mass increases hydrostatic pressure. Therefore downwelling and nutrient depletion results, rather than alternatives which require water divergence or mixing.
