Firn Air Isotope and Temperature Measurements from Siple Dome and South Pole

Entry ID: NSIDC-0098

[ Update this Record ]

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 ...
