Antarctica 2013-2014

VeLveT Ice is a project linking the microstructure of ice to the modern deformation and climate history at the coring site on the West Antarctic Ice Sheet (WAIS) Divide (79°28.058' S, 112°05.189' W) (WAIS). Our goals for the December 2013-January 2014 field season are 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 (in the 2015/2016 season). We use an acoustic televiewer downhole instrument to make these measurements. The acoustic televiewer can also provide information to map tilted layers or other anomalies in the borehole wall. We will correlate these measurements with laboratory measurements of ice microstructure and the other ice core and borehole measurements from other WAIS projects.
