Which mechanism reduces ocean gyre intensity following heightened glacial meltwater discharge?

💡 Explanation

When glacial meltwater enters the ocean, increased stratification occurs, because freshwater is less dense, suppressing vertical mixing and weakening momentum transfer in gyres. Therefore strengthened thermohaline stratification results, rather than eddy formation, Coriolis shifts, or modified upwelling, which involve different circulation processes at larger scales.
