Kinetic energy six jets of the Antarctic Circumpolar Current (ACC), and of synoptic eddies generated by these jets is studied in application to the near-surface layer of the Antarctic Circle on the base of the satellite altimeter data during 1993–2015. The main results of the study were as follows: a) prevalence of the energy of middle jet of the Subantarctic Current over energy of the rest ACC jets in the whole of the Antarctic Circle; b) five times excess of the mean energy of jets proper over the mean summary (cyclones plus anticyclones) energy of eddies; c) two times excess of mean energy of cyclonic eddies over energy of anticyclones.
