How does temperature-driven vertical turnover occur, and what is its importance?
What will be an ideal response?
Vertical turnover occurs in estuaries in which the upper layer of water is cooled in the winter. This cooling results in denser surface water than water below and causes surface water to sink and deeper water to rise to the top. Turnover has the effect of allowing nutrients to cycle between the water column and the sediments.
