Abstract
This data set contains depth profiles for delta carbon-13 (&#948;13C) and delta deuterium (&#948;D) of methane (CH<sub>4</sub>) 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 CH<sub>4</sub> 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).
