← GeographyWhich consequence results when surface water convergence intensifies within subtropical gyres?
A)Increased downwelling and nutrient depletion✓
B)Elevated sea surface temperatures globally
C)Reduced stratification within the mixed layer
D)Strengthened coastal upwelling currents locally
💡 Explanation
Increased surface water convergence enhances downwelling; therefore, nutrient-rich deeper waters cannot upwell because downwelling physically suppresses 'Ekman transport', rather than driving upwelling or altering overall sea temperatures.
