Abstract
Geostrophic currents in the Drake Passage are studied using the data of two hydrographic sections across the passage occupied in December 2003 and November 2005 along with satellite altimetry data. A conclusion is reached that the altimetry correction of the geostrophic currents has advantages compared to the correction made on the basis of the lowered acoustic Doppler current profiler data. A number of new results about the structure and intensity of the ocean currents in the Drake Passage are obtained; the main one is the distinguishing of several abyssal currents of westward direction confined to deep passages in the bottom topography.
