Which mechanism causes changes in major ocean stream salinity when glacier ice melts?

💡 Explanation

Thermohaline circulation is altered because freshwater influx decreases the density of surface waters, therefore slowing down sinking and mixing, rather than directly influencing upwelling due to wind differences or altering channels.
