Which process strongly reduces regional ocean surface salinity near Greenland?

💡 Explanation

When glacial melt rate increases, fresh water influx into the ocean increases glacial meltwater discharge reducing salinity because pure ice meltwater lacks dissolved salts, disrupting thermohaline circulation. Therefore increased discharge results, rather than upwelling, deposition, or subsidence causing increased salinity or currents.
