Velvet Ice is a project linking the microstructure of ice to the modern deformation and climate history at West Antarctic Ice Sheet (WAIS) Divide. Researchers will use an acoustic televiewer downhole instrument to measure the shape and tilt of the borehole at high resolution to form a basis for measuring future changes in borehole shape and tilt. The acoustic televiewer can also provide information to map tilted layers or other anomalies in the borehole wall. Researchers will correlate these measurements with laboratory measurements of ice microstructure and the other ice core and borehole measurements from other WAIS Divide projects.

Field Season Overview

Researchers with this project will fly by LC-130 aircraft to the WAIS Divide Field Camp, where they will reside for the duration of their stay. They will be logging the WAIS borehole with two different instruments and will also make day trips by snowmobile to collect phase-sensitive radar measurements.
