Major advance of South Georgia glaciers during the Antarctic Cold Reversal following extensive sub-Antarctic glaciation ...
The history of glaciations on Southern Hemisphere sub-polar islands is unclear. Debate surrounds the extent and timing of the last glacial advance and termination on sub-Antarctic South Georgia in particular. Here, using sea-floor geophysical data and marine sediment cores, we resolve the record of...
