Black Carbon as a Source of Trace Elements and Nutrients in Ice Sheet of King George Island, Antarctica
Enormous deglaciation in the polar and mountainous regions of the Earth is associated not only with large-scale climatic changes but also with the global transfer of black carbon (BC) microparticles, which accumulate on the surface of glaciers and lead to changes in albedo and the rate of degradatio...
