Abstract

Using a profiling current meter combined with several fixed-level current meters, the pattern of circulation in the Canary Current upwelling region off Cabo Bojador (26°N) has been observed. This pattern is discussed in relationship to the hydrography. The following main features were found: 1. (1) general equatorward alongshore flow, decreasing in speed with depth and nearly in geostrophic balance; 2. (2) a near-surface, near-shore maximum of alongshore velocity over the continental shelf; 3. (3) a weak poleward flow beneath 400 m along the continental slope; 4. (4) a double-celled cross-shelf circulation system; 5. (5) a bottom mixed layer over the shelf associated with onshore flow originating below 225 m offshore; 6. (6) high variability due principally to semidiurnal internal tides.
