DISTRIBUTION OF CHEMICAL COMPONENTS BETWEEN ATMOSPHERE AND SNOW PHASES IN EAST QUEEN MAUD LAND
It is certain that all chemical components contained in Antarctic ice have been derived from the atmosphere. However, the detailed mechanism of their inclusion into glacier ice is still a subject of research. Comparisons of chemical composition of atmospheric aerosol and falling snow or surface depo...
