Physical Properties of the WAIS Divide Deep Core
Entry ID: alley_0539578

[ Update this Record ]

Summary
Abstract: This award supports a five-year collaborative project to study the physical-properties of the planned deep ice core and the temperature of the ice in the divide region of the West Antarctic Ice Sheet. Data include depths of crusts and annual layers observed visually in the ice core, density of the ice core determined by flotation in isooctane, and images and counts of bubble number-density. Data sets will be completed and extended under the follow-on grant to this one.

Purpose: The intellectual merit of the proposed research is to provide fundamental information on the state of the ice sheet, to validate the integrity of the climate record, to help reconstruct the climate record, and to understand the flow state and history of the ice sheet. This information will initially be supplied to other investigators and then to the public and to appropriate databases, and will be ... View entire text

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