Abstract : This report is a summary of all RAFOS float data collected during the 1993-1995 study of the North Atlantic Current (NAC) and adjacent waters in the Newfoundland Basin. The objective of the program was to study the structure of the currents in the NAC region and the exchange of waters between the subtropical and subpolar gyres in the Newfoundland Basin. One hundred floats were deployed during three separate cruises in Summer 1993, Fall 1993, and Fall 1994. The floats were ballasted for a density surface corresponding to sigma-t= 27.2 or 27.5. They were designed to cycle once or twice a day to surfaces 0.1 sigma-t units above and below the targeted density surface in order to determine changes in stratification and temperature along the trajectories. Most float missions had a duration of ten months. The floats were tracked using four moored sound sources deployed in the Newfoundland Basin during the first cruise, and recovered in June 1995. We present the trajectories, velocity time series, and pressure and temperature time series for all floats that could be processed. Of the 100 RAFOS floats deployed, all but eight returned useful data.
