This is the final data report of all RAFOS acoustically tracked float data collected during the 1994-1997 Boundary Current Experiment BOUNCE study of the Deep Western Boundary Current DWBC in the North Atlantic Ocean. The overall objective of the program was to obtain the first comprehensive description of the North Atlantic DWBCs variability over a large path segment from Cape Hatteras to the Grand Banks. The experiment was comprised of CTD, tracer, and RAFOS float observations to achieve both Eulerian and Lagrangian descriptions of the DWBC. The three main objectives of the Lagrangian float study were 1 to determine fluid parcel pathways in the DWBC and identify regions of exchange with the interior, 2 to estimate the mean speed and variability of fluid parcels at two different levels in the DWBC, and 3 to study the kinematics and potential vorticity dynamics of fluid parcels in the DWBC at the Gulf Stream crossover point near Cape Hatteras. Thirty floats were deployed 15 were designed to be isopycnal floats, and 15 were isobaric floats.
