← GeographyWhich environmental outcome occurs when persistent offshore winds weaken?
A)Reduced nutrient transport to surface✓
B)Increased marine snow deposition
C)Enhanced methane clathrate releases
D)Decreased deep water oxygen depletion
💡 Explanation
Weakened offshore winds reduce Ekman transport influencing upwelling, because, with less upwelling, fewer nutrients reach surface waters; therefore, surface productivity decreases, rather than increased benthic deposition or altered gas release. The mechanism at play is nutrient upwelling.
