← GeographyWhich thermocline depth results when large ocean gyres intensify?
A)Decreased depth and nutrient upwelling
B)Increased depth and nutrient stratification✓
C)Unchanged depth and stable conditions
D)Variable fluctuating depth intermittently
💡 Explanation
Increased gyre intensity causes Ekman transport and convergence, resulting in downwelling. This deepens the thermocline due to convergence because warm surface water is pushed downwards, therefore the nutrient distribution stratifies rather than upwells as it does in upwelling zones.
