Resolving the internal and basal geometry of ice masses using imaging phase-sensitive radar ...
ABSTRACTThe phase-sensitive radio-echo sounder (pRES) is a powerful new instrument that can measure the depth of internal layers and the glacier bed to millimetre accuracy. We use a stationary 16-antenna pRES array on Store Glacier in West Greenland to measure the three-dimensional orientation of di...
