1. Atmospheric Nitrate Isotopic Analysis at Amundsen-Scott South Pole Station, A Twenty-Five Year Record [NSIDC-0281]
This data set contains snow pit measurements of oxygen isotopes, 17O and 18O, in nitrate and ion concentrations, and surface measurements of oxygen isotopes in nitrate and in ...

2. Cenozoic Seawater Sulfate Sulfur Isotopic Data [NOAA_NCDC_PALEO_2006-076]
A continuous seawater sulfate sulfur isotope curve for the Cenozoic with a resolution of ~1 million years was generated using marine barite. The sulfur isotopic composition decreased from 19 to ...

3. Cretaceous Seawater Sulfur Isotopic Data [NOAA_NCDC_PALEO_2006-077]
The exogenic sulfur cycle is tightly coupled with the carbon and oxygen cycles, and therefore a central component of Earth's biogeochemistry. Here we present a high resolution record of the sulfur ...

4. Investigation of Atmospheric Chemistry and Dynamics Through Oxygen and Sulfur Isotopes in Volcanic Sulfate [thiemens_NSF0338363]
This dataset contains chemical measurements of volcanic sulfate deposits in Antarctic snow, in a collaborative project between South Dakota State University (SDSU, Jihong Cole-Dai, PI) ...

5. Multiple Isotope Analysis of Sulfate in the West Antarctic Ice Sheet Divide Ice Core [NSIDC-0479]
This data set contains measurements of multiple sulfur and oxygen isotopes from sulfates, from an ice core drilled at the West Antarctic Ice Sheet (WAIS) Divide site in 2005. The initial sulfate measurements, ...

6. Multiple-isotope Analysis of Nitrate and Sulfate in the West Antarctic Ice Sheet Divide Ice Core [thiemens_0538520]
The goal of this project is to use the isotopic composition of sulfate and nitrate in the WAIS Divide core to help place better constraints on the oxidant composition of the pre-industrial atmosphere. ...

7. South Pole Atmospheric Nitrate Isotopic Analysis [thiemens_0125761]
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 ...
