摘要

The feasibility and effectiveness of satellite altimetry and radiometry using for studying the thermodynamic structure and dynamics of the Southern Ocean were demonstrated. Analysis of the temporal variability of sea level anomalies (SLA), calculated from satellite altimetry data allowed to specify the spatial position of the Antarctic Circumpolar Current (ACC) boundaries and the analysis of sea surface temperature (SST) the northern boundary of the Southern Ocean was specified. Detection of ACC boundaries as isoline 112 cm and 30 cm of mean dynamic topography (north and south, respectively) is consistent with eddy activity and meandering regime of the Antarctic Circumpolar Current. The spatial position of isoline value 0,88 °C of SST dispersion can be regarded as the southern boundary of the Subarctic divergence zone, and the spatial position of the isoline 1,64 °C – the southern boundary of the Subtropical convergence zone.
