Krypton and Xenon in the past atmosphere from trapped air in ice cores
Entry ID:
0538630_severinghaus
Summary
Abstract:
Krypton/N2 and xenon/N2 data from trapped air in GISP2 ice core, Greenland (25-14 kyr BP), Dome Fuji ice core, Antarctica (25 kyr BP to recent), and Vostok ice core, Antarctica (125 kyr BP to 110 kyr BP). These measurements are used to infer past changes in mean ocean temperature, based on solubility relationships. Argon and krypton isotopic ratios, along with d15N of N2, are used to make gravitational and thermal fractionation corrections, to reconstruct the atmospheric ratios.
