Which thermocline disruption accelerates nutrient depletion inside ocean gyres?

💡 Explanation

Increased upper-layer stratification prevents vertical mixing because buoyancy inhibits the upwelling of nutrient-rich waters from the ocean depths, therefore nutrients deplete, rather than replenish through mixing caused by density diffrences.
