Which outcome is accelerated in fjord ecosystems experiencing reduced sea ice cover?

💡 Explanation

Increased density-driven circulation occurs because less sea ice results in temperature gradients at the surface which increases the thermohaline forcing; therefore, deep water renewal occurs more efficiently, rather than slower, which could restrict nutrient flow.
