Última A 6 year record of baroclinic transport variability of the Antarctic Circumpolar Current at 140 degrees E derived from expendable bathythermograph and altimeter measurements ArchiMer Rintoul, Sr; Sokolov, S; Church, J. Repeat hydrographic sections across the Antarctic Circumpolar Current are used to derive an empirical relationship between upper ocean temperature and the baroclinic transport stream function. Cross validation shows this relationship can be used to infer baroclinic transport (above and relative to 2500 dbar) from temperature measurements with an error of a few per cent. The mean transport distribution derived from 31 austral summer expendable bathythermograph (XBT) sections over a 6 year period consists of westward flow immediately south of Tasmania, a broad band of strong eastward flow between 50degrees and 55degreesS, and three cores of eastward flow south of 55degreesS. By defining a second empirical relationship between surface dynamic height and...

Comparison of the discontinuous XBT record with a continuous (weekly average) satellite-based SST data set confirms that the XBT sampling is adequate to resolve interannual variability. Significant correlations are found between changes in surface and subsurface temperature along much of the section. In the Subantarctic zone, surface and subsurface changes are coherent because deep convection in winter homogenizes the upper 600 m, and the summer mixed layer temperature reflects the preconditioning of the previous winter. At other latitudes the...

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...
