Anisotropy, Abrupt Climate Change, and the Deep Ice in West Antarctica

Entry ID: waddington_0636996

[ Update this Record ]

Summary

Abstract: This record includes two datasets and accompanying code.

The anisotropic flow dataset provides velocity and fabric evolution of anisotropic ice for several numerical experiments. The experiments examine how differing stress regimes and initial c-axis crystal fabrics can affect flow. Contained are VTU format files of finite element output of velocity (m/yr) as well as the second order fabric ...

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.
