An interpretation of the double T-S maxima in the Mediterranean outflow using chemical tracers
TSD observations of the Mediterranean outflow into the N.E. Atlantic were supplemented by measurements of nitrate, silicate, and phosphate. Apart from the normal salinity maximum at 1200 m, the occurrence of a T-S maximum at a depth of about 700 m in the Atlantic has often been observed. The chemical data suggest that this upper maximum is due to the release of water from a relatively shallow depth in the Straits of Gibraltar.
