| Abstract: | Within the framework of the general linear statement of the problem, we determine the conditions of generation of a geostrophic
current in a layer of uniform rotating fluid for small displacements of the bottom of a basin. We deduce an equation relating
the equilibrium shape of the surface of the fluid with residual deformations of the bottom and find its general solution.
It is shown that the geostrophic current is generated only in the presence of residual deformations. We present numerical
estimates of the intensity of the generated geostrophic formation for a model of motion of the bottom. The investigated mechanism
of generation of geostrophic vortex fields is especially efficient in the shelf zone of the ocean.
