Which mechanism disrupts thermohaline circulation when glacial meltwater input increases in North Atlantic streams?

💡 Explanation

When substantial glacial meltwater enters North Atlantic streams, reduced salinity causes density stratification, inhibiting convective overturning because denser, saltier water can no longer sink. Therefore, stratification disrupts the thermohaline circulation, rather than upwelling, shear formation, or increased carbon sequestration which require different density dynamics.
