Directory entires that have specified Koldewey Station, Ny-Ålesund/Spitsbergen as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

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.
