Summary
Abstract: This data set includes d15N, d18O/2, dO2/N2/4, d40Ar/4, d38/Ar/2, d84Kr/48, and d132Xe/96 values for air drawn from the top 15 to 50 m of firn at the South Pole (summer and winter 1998) and a site at Siple Dome (summers 1996 and 1998). Data also include related firn temperature measurements. The objective of this research was to better understand thermal fractionation processes affecting records ... View entire text
