Group: Summary

   These data describe the concentration and carbon-isotopic composition (d13CO2) 
   of atmospheric CO2 from air trapped in ice between 27,000 and 1,300 years 
   before present from Taylor Dome, Antarctica. Data are used to investigate the 
   causes of the CO2 concentration increase that occurred during the transition 
   between the last glacial maximum (LGM) and the Holocene. Data are in 
   tab-delimited ASCII and Excel formats, and are available via ftp.
