Which oceanographic consequence results from intensification of the planetary Coriolis effect at higher latitudes?

A)Weakened coastal upwelling currents
B)Increased thermohaline circulation rates
C)Intensified ocean gyre boundary currents
D)Decreased sea surface salinity gradients

💡 Explanation

When the Coriolis effect intensifies poleward, deflection of wind-driven currents strengthens because the force acting perpendicular to the flow increases, concentrating currents along continental boundaries. Therefore, intensified ocean gyre boundary currents result, rather than changes to upwelling, thermohaline circulation, or salinity needing different forcing mechanisms.
