Which outcome frequently restricts nutrient upwelling within a fjord?

💡 Explanation

Density-driven stratification restricts nutrient mixing because denser saltwater underlies less dense freshwater causing a pycnocline, therefore limiting nutrient transport within the water column, rather than promoting upward flow from the seabed.
