Which outcome occurs when wind-driven surface currents converge within an ocean gyre?

💡 Explanation

When surface currents converge within a gyre, Ekman transport causes water to pile up, forming a region of elevated sea surface height and increased pressure, suppressing upwelling. Therefore a surface water lens develops, rather than upwelling, thermocline expansion, or downwelling which involve divergence or coastal processes.
