Which nutrient distribution results when coastal upwelling interacts with major ocean gyre circulation?

💡 Explanation

When coastal upwelling occurs near a major gyre, Ekman transport moves nutrient-rich deep water offshore and along the gyre edge, increasing primary productivity. Therefore, enhanced productivity on eastern gyre margins results, rather than depletion, uniform distribution, or stratification which would require alternative circulation patterns.
