Journal ArticleDOI
A redetermination of the isotopic abundances of atmospheric Ar
Jee-Yon Lee,Jee-Yon Lee,Jee-Yon Lee,Kurt Marti,Jeffrey P. Severinghaus,Kenji Kawamura,Kenji Kawamura,Hee-Soo Yoo,Jin Bok Lee,Jin Seog Kim +9 more
TL;DR: In this article, the isotopic abundances of atmospheric Ar were determined using a dynamically operated isotope ratio mass spectrometer with minor modifications and special gas handling techniques to avoid fractionation.
Journal ArticleDOI
Timing of abrupt climate change at the end of the Younger Dryas interval from thermally fractionated gases in polar ice
TL;DR: In this article, the authors demonstrate that rapid temperature change fractionates gas isotopes in unconsolidated snow, producing a signal that is preserved in trapped air bubbles as the snow forms ice.
Journal ArticleDOI
Eemian interglacial reconstructed from a Greenland folded ice core

TL;DR: In this paper, the North Greenland Eemian Ice Drilling (NEEM) ice core was extracted from folded Greenland ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records.
Journal ArticleDOI
Abrupt Climate Change at the End of the Last Glacial Period Inferred from Trapped Air in Polar Ice
TL;DR: Nitrogen and argon isotopes in trapped air in Greenland ice show that the Greenland Summit warmed 9 +/- 3 degrees C over a period of several decades, beginning 14,672 years ago, supporting a North Atlantic rather than a tropical trigger for the climate event.
Journal ArticleDOI
Northern Hemisphere forcing of climatic cycles in Antarctica over the past 360,000 years

TL;DR: The results indicate that orbital-scale Antarctic climate change lags Northern Hemisphere insolation by a few millennia, and that the increases in Antarctic temperature and atmospheric carbon dioxide concentration during the last four terminations occurred within the rising phase of Northern Hemisphere summer insolation.
