What is mean by a geostrophic current?
What will be an ideal response?
There is a force due to gravity, acting down the gradient of the surface slope that is opposed by the Coriolis Effect. The net effect is a flow of water at approximately 90o to the slope. The result is a geostrophic current that flows approximately perpendicular to the slope of the sea surface around the gyre.
