Neumayer Glacier, South Georgia, 5.6 km retreat 1999-2016

  Comparison of Neumayer Glacier in 1999 and 2016 Landsat images; red arrow indicates 1999 terminus locations, yellow arrows 2016 terminus locations. Purple arrows indicate upglacier thinning. South Georgia sits amidst the circum Antarctic westerlies and its maritime climate leads to numerous glaciers. This region is famous for the endless march of storms parading around Antarctica . The island is south of the Antarctic Convergence, preventing any truly warm season from persisting. …

In 1977 the glacier extended to within 300 m of Antarcic Bay and no proglacial lake existed (BAS map). Neumayer Glacier is a calving glacier that has retreated 4800 m from 1999 to 2014 and is dynamically connected to the …

Neumayer Glacier, South Georgia Retreat

South Georgia sits amidst the circum Antarctic westerlies. This region is famous for the endless march of storms parading around Antarctica. The island is south of the Antarctic Convergence, preventing any truly warm season from persisting. The cool maritime climate leads to numerous glaciers covering a majority of the island and quite low equilibrium line altitudes. Sugden, Clapperton and Pelto (1989-sorry no good link to this paper, one of the …
