Which outcome primarily occurs when coastline geometry impedes a wind-driven oceanic gyre's rotation?

💡 Explanation

When a coastline restricts gyre circulation, pressure gradients increase and cause Ekman transport divergence near the coast because water moving offshore is locally replaced by upwelling. Therefore intensified coastal upwelling currents result, rather than salinity changes, impaired thermohaline circulation, or global temperature increase which each require different forcing mechanisms.
