| Baroclinic transport variability of the Antarctic Circumpolar Current (ACC) near 140 degreesE is estimated from six: occupations of a repeat section occupied as part of the World Ocean Circulation Experiment (WOCE section SR3). The mean top-to-bottom volume transport is 147+/-10 Sv (mean +/-1 standard deviation), relative to a deep reference level consistent with water mass properties and float trajectories. The location and transport of the main fronts of the ACC are relatively steady: the Subantarctic Front carries 105+/-7 Sv at a mean latitude between 51.0 and 52 degreesS; the northern branch of the Polar Front carries 5+/-5 Sv to the east between 53 degrees and 54 degreesS; the southern Polar Front carries 24+/-3 Sv eastward at 59 degreesS; and two... |
