Which outcome occurs when atmospheric high-pressure systems intensify over subtropical ocean gyres?

💡 Explanation

When high-pressure systems intensify, Ekman transport causes surface water convergence in the gyre's center because surface water is transported inward, increasing downwelling and pressing the thermocline deeper. Therefore increased thermocline depth results, instead of increased upwelling or altered nutrient concentration gradient.
