Integrated topographic database for King George Island, South Shetland Islands, with links to shapefiles

SCAR KGIS (SCAR King George Island GIS Project) was an integrated topographic database for King George Island, South Shetland Islands, including the SCAR Feature Catalogue to semantically integrate the data sets. The project, operated by the University of Freiburg, was available at http://portal.uni-freiburg.de/AntSDI as "The Antarctic Spatial Data Infrastructure (AntSDI)". Operation ended in 2007. The remaining data files were archived in shape format (zipped) in projections as recommended by SCAR. The source data was provided by a variety of institutions which were not referenced in the original product.

47 ground-penetrating radar lines of Area 4 - Gravel spit system from Potter Cove, King George Island, Antarctic Peninsula

During two field campaigns (Austral springs 2011 and 2012) the sedimentary architecture of a polar gravel-spit system at the northern coast of Potter Peninsula (Area 4) was revealed using ground-penetrating radar (GPR, Geophysical Survey Systems, Inc. SIR-3000). 47 profiles were collected using a mono-static 200 MHz antenna operated in common offset mode. Trace increment was set to 0.05 m. A differential global-positioning system (dGPS, Leica GS09) was used to obtain topographical information along the GPR lines. GPR data are provided in RADAN-Format, dGPS coordinates are provided in ascii format; projection is UTM (WGS 84, zone 21S).
