← GeographyWhich outcome occurs because of increased runoff into subtropical gyres?
A)Enhanced coastal thermohaline salinity stratification✓
B)Diminished offshore biological pump efficiency
C)Increased deep ocean anoxic zone volume
D)Greater coastal upwelling nutrient availability
💡 Explanation
Enhanced runoff decreases density in surface layers forming strong haloclines, thereby increasing coastal thermohaline salinity stratification; this happens because freshwater input prevents vertical mixing from wind shear therefore hindering downward momentum of mixed layers rather than upwelling facilitation.
