The article discusses a research study on the unconformable and complex englacial stratigraphy in the Byrd Glacier in East Antarctica with crystallized layers and englacial cosets. Researchers used a Global Positioning Radar (GPR) and a deep-sounding system to record 14-bit samples per trace for profiles display in grayscale amplitude format. Also used were differential kinematic global positioning system (GPS) and satellite imagery with Moderate Resolution Imaging Spectroradiometer (MODIS). Results showed images of 5-15 kilometers long cosets from 400-800 meters deep and modified layers as well as unresolved englacial cosets and firn-englacial transition. It also notes the interpretation of parallel folding as indicator of possible stick-slip or basal slip behavior. |
