South Pole Atmospheric Nitrate Isotopic Analysis

Entry ID: thiemens_0125761

[ Update this Record ]

Summary

Abstract: This data set contains oxygen isotope measurements of nitrate from the South
Pole Amundsen-Scott Station. A 6 meter snow pit provides a 25-year record of
nitrate isotope variations and ion concentrations. Monthly surface snow and
weekly aerosol collections yield a year-long record of nitrate isotopic
composition starting December 2003 and ending December 2004.

The data is broken into four sections: 1) ion concentrations in the snow pit by
depth, 2) isotope composition in the snow pit by depth, 3) isotope composition
of nitrate aerosol by date, and 4) isotope composition of surface snow by date.
