Abstract
By means of 7 XBT* sections between South America resp. South Africa and Antarctica the variability of the Subtropical Convergence (STC), the Polar Frontal Zone (PFZ) and the Weddell-Scotia Confluence (WSC) are particularly discussed. Between 45°W and 56°W, the STC is shifted to the South by 2.3 degrees of latitude confining a tongue of subtropical surface water near the continental slope of the Patagonian shelf. Further South, the PFZ is displaced to the North by 7 degrees of latitude between 58°W and 39°W. An intense Subantarctic Front has been observed northwestwards of South Georgia. Even East of the South Sandwich Islands the WSC can be detected by a positive temperature anomaly.
