← GeographyWhich process increases along coastal margins within an ocean gyre when stronger offshore winds develop?
A)Coastal upwelling intensity✓
B)Deep ocean salinity gradients
C)Thermocline layer reinforcement
D)Downwelling current propagation
💡 Explanation
When offshore winds intensify, Ekman transport moves surface water away from the coast, driven by the Coriolis effect within the gyre, stimulating coastal upwelling as deeper water rises to replace removed surface water. Therefore upwelling intensity increases, rather than alternative options which are driven by density or onshore flow dynamics.
