Methane Isotopes from the WAIS Divide Ice Core
Entry ID: NSIDC-0435

[ Update this Record ]

Summary
Abstract: This data set includes methane (CH4) isotope data from the West Antarctic Ice Sheet (WAIS) Divide ice core, WDC05A, in Antarctica. The data include depth, gas age, and the isotopic composition of methane (∂13C and ∂D of CH4). The ice core was collected during the 2005-2006 Antarctic field season. The CH4 isotope data was generated in 2008 using wet extraction methodology. Samples span ... View entire text
