Which outcome occurs when coastal upwelling is significantly reduced due to decreased wind stress?

💡 Explanation

When wind stress decreases, reduced upwelling diminishes the vertical transport of nutrient-rich deep water to the surface because wind-driven water displacement is weaker, limiting nutrient replenishment in the photic zone. Therefore nutrient depletion results, rather than increased salinity, enhanced stratification, or decreased oxygen concentrations which require different current or mixing mechanisms.
