Abstract
In September-October 1988 and in April 1989 two 4-week cruises were organized. The first one focused on an anticyclonic crest, and the second one on a cyclonic trough, using a CTD and a continuously profiling acoustic Doppler current profiler (ADCP). The cross-stream sections of velocity exhibit the typical pattern of a single velocity maximum with a narrow zone of cyclonic shear and a broad region of anticyclonic shear. Shear vorticity greatly enhances -(f/p)dp/dz on the cyclonic side and weakens it to a distinct minimum in the center of the current at the crest. For the trough, the evidence suggests that the opposite is true. -from Authors
