Multiple-isotope Analysis of Nitrate and Sulfate in the West Antarctic Ice Sheet Divide Ice Core
Entry ID: thiemens_0538520

Abstract: 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. An important premise is that the combined use of multiple isotope ratios, which have different sensitivities, will place stronger constraints on paleoxidants than a single ratio could provide.

Description: The U.S research community is conducting a deep ice coring project in West Antarctica for studies of climate, ice sheet history and cryobiology. This project is collecting a deep ice core from the West Antarctic Ice Sheet (WAIS) ice flow divide and integrating approximately 20 separate but synergistic projects to analyze the ice and interpret the records
