Note on the shelf break upwelling off the southeast coast of Brazil (lat. 26º30'S)
A western margin frontal zone is described, from measurements of temperature, salinity and currents, in a section taken with R/V "Prof. W. Besnard" in December 1980, crossing the shelf break border at latitude 26º30'S. The analyses of the sections showed consistently the occurrence of...

| description | A western margin frontal zone is described, from measurements of temperature, salinity and currents, in a section taken with R/V "Prof. W. Besnard" in December 1980, crossing the shelf break border at latitude 26º30'S. The analyses of the sections showed consistently the occurrence of an ascension of the T and S isolines over the shelf break. Simultaneous current measurements showed a surface eddy structure with clockwise circulation and anti-clockwise circulation having a common stem over the break characterizing a shelf break upwelling. |
