Summary
Abstract: The origin of ground ice at high elevations (>1000m) throughout the Dry Valleys of Antarctica was investigated as the origin is unclear because there is no obvious comtemporary source of water. A model to explain the occurrence of ground ice in glacial sediments and bedrock was developed from previous work at Table Mountain. The model is based on mineralogical, chemical and isotopic analyses of ... View entire text
