Causes for GPR reflections in an alluvial permafrost environment

Updated 2002-03-26

3-D GPR (ground penetrating radar) profiling of permafrost deposits and examination of their geocryologic and sediment properties for verification of GPR profiles. The scientific project has the following aims: To improve the understanding of how GPR (ground penetrating radar) reflections are generated in frozen ground; to reveal the main factors (geophysical and sedimentary) controlling electromagnetic reflection characteristics and their spatial continuity as examplarily studied along a continuous permafrost section, i.e. to distinguish between physical (dielectricity, conductivity and density) and sedimentary (ice/water content, grain size distribution, content of organic matter, texture) properties and estimate their proportionate quantity on the origin of the wave reflections.
