Neon and other noble gas measurements in ice core samples from Vostok and Megadunes
Entry ID: severinghaus_0230448

[ Update this Record ]

Summary
Abstract: Neon/argon ratios in ice core samples from three sites: GISP2, Greenland, and
Vostok and Megadunes, Antarctica. These samples show that neon is not
preserved in ice core samples, but rather leaks out of stored samples. The
Megadunes samples were taken using "Craig Can" technology, which involves
putting the sample in an evacuated container immediately after core recovery.
This prevents the loss of neon. These Megadunes samples show neon values close
to atmospheric, in contrast to samples that have been stored in freezers for
years, and support the interpretation that neon leaks out of stored samples.
