Which consequence occurs when a coastline obstructs gyre circulation?

💡 Explanation

Coastline obstruction forces water upwards via Ekman transport, therefore upwelling increases where deflected gyre circulation impinges on shallow-water regions near the coast, rather than altering salinity, thermocline, or deep-sea currents.
