Title: Investigation of the Stratigraphy and Time Scale of the WAIS Divide Ice Core Using Electrical Methods
Description:
Abstract:
This award supports a project that is part of the West Antarctic Ice Sheet Divide (WAIS Divide) program; which is a multi-disciplinary multi-institutional program to investigate the causes of natural changes in climate, the influence of the West Antarctic ice sheet on sea level, and the biology of deep ice. The WAIS Divide core will be unique among Antarctic ice cores in that it will have discernable annual layers for the last 40,000 years. A critical element of the program is to determine the age of the ice so that the climate proxies measured on the core can be interpreted in terms of age, not just depth. This project will make electrical measurements that can identify the annual layers. This information will be combined with information from other investigators to develop an annually resolved timescale over the last 40,000 years. This timescale will be the foundation on which the recent climate records are interpreted. Electrical measurements will also be used to produce two-dimensional images of the ice core stratigraphy; allowing sections of the core with abnormal stratigraphy to be identified.

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 40 separate but synergistic projects to analyze the ice and interpret the records.
