Salinity anomalies of about -1.0 psu were observed over a period of several months in a surface layer 50 m thick near the equator. Below this fresh layer there was a steep halocline having very little temperature stratification, so that the density changes were dominated by salinity. In December 1991, eastward surface velocities in the fresh jet at 170°W were 100 cm s-1 with a shear of about 40 cm s-1 in the top 100 m; the core of the jet was about 200 km in width, centered at 1.5°S. The jet decayed and vanished over the next few months, though the surface halocline remained.
