← GeographyWhich outcome occurs when increased offshore wind stress induces coastal upwelling along continental margins?
A)Nutrient replenishment in surface waters✓
B)Stratification of the water column
C)Increased ocean surface temperatures
D)Decreased marine biodiversity
💡 Explanation
When increased offshore wind stress occurs, Ekman transport causes surface waters to move offshore, which draws nutrient-rich water from the depths to the surface, stimulating phytoplankton growth. Therefore nutrient replenishment occurs, rather than stratification, increased surface temperatures or decreased biodiversity because upwelling brings the opposite conditions.
