University of Wisconsin scientists are undertaking two projects in Antarctica this year. The first project directed by Charles R. Bently, involves an effort to learn better the seismic wave velocities for the glacier ice under the pressure and temperature conditions prevailing at depth, in order to remove some of the uncertainties involved in the reduction of data obtained by seismic methods. A wave generator will be lowered into a 7100-foot-deep hole by Byrd Station, and measurements will be taken of both compressional and shear waves at many depths. Seismic measurements within and near the hole are also expected to yield new information on the nature of the ice in terms of the structure and distribution of the ice crystals.
