Methane Isotopes in South Pole Firn Air, 2008
This data set contains depth profiles for delta carbon-13 (δ13C) and delta deuterium (δD) of methane (CH4) in South Pole firn air. The investigators obtained air samples from two boreholes during December 2008 and January 2009, and subsequently determined isotope ratios at 18 depths. The profiles represent a roughly 100-year history of the isotopic composition of CH4 at South Pole Station (no depth-age model provided).
Data are available via FTP as an ASCII text file (.txt) and a Microsoft Excel file (.xlsx).
