(a) An example of current speed in the GS region from altimeter data. Magenta lines denote the location of the Oleander line, AX10 transect, and the Florida Straits. (b) Zonal velocity (black line) and speed (red line) along 61°W (green line in (a)). Blue and green circles indicate the GS center determined from a SSH contour (first guess) and the maximum speed close to the SSH contour, respectively. (c) GS position at 72°W from the AX10 transect (black line) and SSH (red line). (d) GS position at 70°W from an ADCP (black line) and SSH (red line). (e) GS transport (0–800 m) derived from the AX10 transect (black line) and cross-front SSH difference (red line). (f) Florida Current transport from cable measurements (black line) and SSH differences across the Florida Straits (red line).
