Abstract : In spring of 1972, 32 STD stations with 14 Nansen casts were occupied in the Cayman Sea and Yucatan Channel. Vertical sections of temperature, salinity and sigma-t along the central axis of the sea were determined. A computer program was developed for correcting digitized salinity-temperature-depth recorder (STD) data for time lag of the temperature sensor against the conductivity sensor and for removing sharp spikes. From temperature, salinity and sigma-t values thus determined every meter at five stations, mean values and the perturbations were obtained to a depth of 1500 m.
