Which outcome results when the ocean's mixing layer weakens?

💡 Explanation

An unstable mixing layer hinders nutrient cycling via *turbulent diffusion*, because deep nutrients reach the surface less effectively; therefore, phytoplankton are nutrient-limited, and algal booms intensify rather than thermocline reversal, equalization, or temperature variance reduction under prevailing conditions.
