The effects of bottom topography on ocean currents are considered. it is shown that a laminar laboratory model with height to width ratio differing from that of large scale geophysical motions can be used to model topographic effects on ocean currents. The governing vorticity equation is solved analytically for the flow over long constant cross-section ridges. The vorticity equation, given by a balance of inertial, Ekman suction and topographic terms, is solved numerically for the behavior of the Antarctic Circumpolar Current in the vicinities of both the Macquarie and Kerguelen-Gaussberg Ridges.
