Long-term mean SSTs (contours) and standard deviations of SST anomalies (shading) for the (a) austral summer (ONDJFM) and (b) winter (AMJJAS) season. Contour interval is 2.5°C; 0°C and 10°C isotherms are marked. Also, the different sectors of Antarctica are shown relevant to this present study. EAIS and WAIS represent East Antarctic Ice Sheet and West Antarctic Ice Sheet, respectively.
