Abstract
Nansen-bottle data and deep-current measurements taken along 132°E between 35°S and 64°S from December 1969 through January 1970 are used to investigate the velocity structure of the Antarctic Circumpolar Current in this region. A narrow countercurrent is observed over the Indian-Antarctic ridge. Hydrographic sections made in other longitudes suggest that the countercurrent occurs along the full length of the ridge south of Australia. The net flux of water through the section at 132°E is 233×106 m3/sec, which compares very well with the measured flux through Drake Passage.
