Which mechanism disrupts deep ocean nutrient circulation after a large freshwater influx from glacial melt?

💡 Explanation

When freshwater influx occurs, density stratification is intensified because freshwater is less dense than saltwater, inhibiting the sinking of cold, salty water that drives the thermohaline circulation of nutrients. Therefore, density stratification halting thermohaline sinking results, rather than turbidity, pH changes, or amplified upwelling, each of which require different processes.
