Firn Air Study in the Megadunes Near Vostok, Antarctica
Entry ID: severinghaus_nsf0230452

[ Update this Record ]

Summary
Abstract: 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 "convective zone" of vigorous wind-driven
mixing can prevent gas fractionation in the upper one-third of the polar firn
layer. In the megadunes, ultralow snow accumulation rates lead to ... View entire text
