Which nutrient redistribution results when Sargasso Sea gyres weaken?

💡 Explanation

Surface phytoplankton growth increases because gyre weakening reduces downwelling, hindering nutrient transport to deeper waters, therefore surface concentration increases rather than nutrient depletion along coastal regions is seen.
