Abstract : Six shallow tows were sequentially made during CHAIN cruise 102 in the early spring of 1972 in the area east of Bermuda. Using a new towed data sampling system introduced by Katz and Nowak (1973), digital recordings were made simultaneously of pressure, temperature, conductivity and sound velocity in the upper 50 m of the ocean. XBT's were launched and surface salinity continuously sampled. The measurements cover a time of 74 hours and a distance of about 500 nautical miles (nm). In the XBT cross section are seen the first indications of the major delineating features of the tow data: a thermal front and a cold water ring of the Gulf Stream. The surface layer stratification and the sound velocity field is given by the tow data. Using a horizontal T-S and sound velocity-density relationship, four different kinds of water are defined.
