Which process explains the altered nutrient distribution due to coastal upwelling disruption by negative Indian Ocean Dipole events?

💡 Explanation

Negative IOD events weaken trade winds, reducing the strength of Ekman transport and minimizing the upwelling of nutrient-rich waters because the surface layer is not effectively pulled away. Therefore, nutrient distribution patterns are less pronounced, rather than intensified by factors unrelated to wind-driven mixing.
