Abstract Data obtained from a line of absolute current profiler (PEGASUS) and CTD stations at 26.5°N, east of Abaco Island in the northern Bahamas, are used to estimate the average transport, and overall level of variability, of the deep (below 800 m) southward flow associated with the so-called “Deep Western Boundary Current”(DWBC) at this latitude. From April 1985 to September 1987 a total of 11 sections were made along a line extending from near the island boundary to 85 km offshore as part of the Subtropical Atlantic Climate Studies (STACS) program. In all but two cases (when PEGASUS data were obtained over the total depth), absolute velocities were determined from 0 to about 3000 db while CTD derived relative velocities were determined over the total depth. Using the combined datasets, it is possible to reference the relative geostrophic velocity with PEGASUS data, thereby obtaining an estimate of the absolute southward transport of the deep flow. The average value of transport determined in this man...
