Figure 8: South Georgia glacial history compared against published Southern Hemisphere glacial and climatic records.

From: Major advance of South Georgia glaciers during the Antarctic Cold Reversal following extensive sub-Antarctic glaciation

Figure 8

(a) Age constraints for events during the last deglaciation and termination on South Georgia from this study and published records, and a new glaciation curve inferred from these observations. These events are compared with (b) glacier fluctuations from other Southern Hemisphere sites (refs 28, 34, 73, c) grey-scale density (GSD) record from Tønsberg Lake, north South Georgia, as a proxy for minerogenic input (ref. 25, d) reconstructions of the northern sea-ice edge (blue line) and southern boundary of the polar front (orange line) for the last deglaciation in the Atlantic sector of the Southern Ocean (ref. 75, e) EPICA Dome C (EDC) Ice core Deuterium content record, and (f) Summer sea-surface temperature (SST) record for core PS2090-1, south of the Antarctic Polar Front (ref. 75).
