Microparticle/Tephra Analysis of the WAIS Divide Ice Core, Antarctica

Entry ID: kreutz_0636740

[ Update this Record ]

Summary

Abstract: This award supports a project to perform continuous microparticle concentration and size distribution measurements (using coulter counter and state-of-the-art laser detector methods), analysis of biologically relevant trace elements associated with microparticles (Fe, Zn, Co, Cd, Cu), and tephra measurements on the WAIS Divide ice core.

Purpose: The intellectual merit of the project is that it will help in establishing the relationships among climate, atmospheric aerosols from terrestrial and volcanic sources, ocean biogeochemistry, and greenhouse gases on several timescales which remain a fundamental problem in paleoclimatology. The atmospheric mineral dust plays an important but uncertain role in direct radiative forcing, and the ...

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.
