Group: Summary
This data set includes records of the delta carbon-13 (δ13C)
of methane (CH4) in firn air from the South Pole and trapped in
bubbles in a short ice core from Siple Dome, Antarctica. Using two firn air
samples, one from January 1995 and the other from January 2001, investigators
reconstructed records of the isotopic composition of paleoatmospheric methane
covering the last 2 centuries, from 1820 to 2001.
Data are in Microsoft Excel and Microsoft Word formats and are available via
FTP.
