In ice-free surfaces of King George Island (South Shetland Islands, Maritime Antarctica) the main formations along topographic chronosequences consist of weathered volcanic rock outcrops, marine platforms, deposits of glacial materials such as moraines, and present day beaches. In relation with recent glacier retreat processes of sediment redistribution in unstable paraglacial environments are highly active in the area. Together with soil particles the mobilization of associated soil organic carbon (SOC) can be further enhanced under conditions of climate change by melting snow and ice. In February 2015 we conducted a selective sampling of reference sites on marine platforms and moraines to be compared with surface sediments recently deposited in lakes on the platforms and in the proglacial environment of the Bellingshausen Ice Dome.
