The last decade of research in the Southern Ocean has shown that the Antarctic Circumpolar Current (ACC) is a complex system composed of narrow, high-speed currents separated by broad, quiescent zones. The circumpolar nature of this structure was examined using position and velocity data obtained from approximately 300 surface-drifting buoys deployed in the Southern Ocean during the First GARP Global Experiment (FGGE). The distribution of buoys on 1¿¿1¿ squares shows that in some regions, most notably south of Australia, the buoys form three ccoherent bands of high buoy density which are separated by regions of low buoy density. The latitudes of these bands coincide with those of the Subtropical Front, Subantarctic Front, and Polar Front. The further examine the relationship between these fronts and buoy distribution, locations of the three fronts, determined from historical hydrographic data, were used to partition the buoys into zonal bands corresponding to front and nonfront regions. A mean buoy density and mean near-surface speed were then computed for each zonal band. High buoy densities were associated with all three fronts in the region south of Australia. Other regions also showed a tendency, although not as pronounced, for buoys to accumulate in fronts. The mean near-surface speeds suggest that the Subantarctic and Polar Fronts are circumpolar. Moreover, the mean near-surface speeds associated with the three frontal regions differ. Speeds within the Subantarctic and Polar Front regions are approximately twice that associated with the Subtropical Front.
