← GeographyWhich outcome occurs when localized bathymetric sills disturb upwelling?
A)Variable nutrient delivery to surface✓
B)Enhanced thermocline layer stability
C)Increased coastal erosion downstream zones
D)Decreased sea surface temperatures overall
💡 Explanation
Variable nutrient delivery occurs because bathymetric sills interfere with the continuity of upwelling flow, promoting localized turbulence zones near the topography, a process of flow distortion. Therefore, nutrient supply varies down current rather than providing uniformly distributed flow.
