Abstract
Twenty-one RAFOS floats were tracked at depths of 200-1000 meters in and around several North Brazil Current Rings between
November 1998 and June 2000. This was part of an experiment to study the role of these current rings in transporting upper level
South Atlantic water across the equatorial-tropical gyre boundary into the North Atlantic subtropical gyre. The float trajectories in
combination with surface drifters and satellite imagery reveal the sometimes complex life histories of several rings and their fate
as they collide with the Lesser Antilles Islands. This report describes the float trajectories, the velocity, temperature, and depth
time series, and a preliminary analysis of the float data.
