Which consequence results when deep ocean salinity decreases significantly?

💡 Explanation

A reduction in salinity decreases water density and impacts the convective portion of thermohaline circulation because sinking is inhibited; therefore, circulation weakens, rather than strengthens, since density differences drive this global process.
