Which outcome occurs when increased Antarctic ice melt disrupts upwelling?

💡 Explanation

Reduced nutrient supply in surface waters will result because Melting ice introduces freshwater which reduces the density gradient that drives thermohaline upwelling, therefore decreased nutrient supply limits phytoplankton growth rather than enhanced blooms, differing significantly from normal upwelling systems.
