We use vertical profiles obtained by salinity-temperature-depth and conductivity-temperature-depth profilers in winter 1977 and by airborne expendable bathythermograph in winter 1979 to examine the circulation east of the southern Lesser Antilles. The major flow feature, present both years, was an elongated cyclonic loop which apparently directed much of the flow toward Grenada Passage. Within the salinity maximum layer we found high salinites (>37%o) in Grenada Passage; such water was previously thought to enter the Caribbean only through more northern passages. An anomalous water mass, present at a few stations where the salinity maximum layer was relatively thicker, may have been an eddy similar to eddies observed elsewhere. Net westward transport between Tobago an Barbados was 15¿106 m3/s (relative to 700 dbar), about one-half the total flow into the Caribbean Sea.
