Abram, Nerilie; Thomas, E.R.; McConnell, J.R.; Mulvaney, Robert; Bracegirdle, Thomas J; Sime, Louise C; Aristarain, Alberto J


This study uses ice core methanesulphonic acid (MSA) records from the Antarctic Peninsula, where temperatures have been warming faster than anywhere else in the Southern Hemisphere, to reconstruct the 20th century history of sea ice change in the adjacent Bellingshausen Sea. Using satellite-derived sea ice and meteorological data, we show that ice core MSA records from this region are a reliable proxy for regional sea ice change, with years of increased winter sea ice extent recorded by...[Show more]
