12. Firn Air Study in the Megadunes Near Vostok, Antarctica [severinghaus_nsf0230452]
This award supports a study of the chemical composition of air in the snow layer (firn) in a region of "megadunes" near Vostok station, Antarctica. It will test the hypothesis that a deep ...


13. Fractionation of gases in polar ice during bubble close-off: firn air Ne, Kr and Xe observations [severinghaus_nsidc0290]
Gas ratios in air withdrawn from polar firn (snowpack) show systematic enrichments of Ne/N2, O2/N2 and Ar/N2, in the firn?ice transition region where bubbles are closing off. Air from ...


14. Inert Gases in Firn Air and Shallow Ice at the WAIS Divide Site [severinghaus_0440701]
