Which mechanism is disrupted when increased freshwater input from glacial melting slows coastal upwelling circulation?

💡 Explanation

when increased freshwater melts slows coastal zone circulation, reduced vertical salinity gradient disrupts the density-driven sinking because freshwater is less dense, weakening the overall thermohaline processes. Therefore, vertical salinity gradient changes results, rather than density increases or altered thermoclines if density-salinity relationship shift.
