Altimeter Measurements of the Volume Transport Through the Drake Passage
From in situ measurements it has been inferred that the variability of flow through the Drake Passage down to 250&n does not depend upon depth (barotropic flow). By making this assumption it is possible to calculate the variability of the volume transport from the surface slope as measured by a...
