International Nuclear Information System (INIS)īaranwal, Vikas C. Helicopter-borne magnetic, electromagnetic and radiometric geophysical survey in Kviteseid area, Lenvik, Troms Geological Survey studies are being used by modelers and resource managers to develop groundwater resource plans for the Arbuckle-Simpson aquifer. Geophysical and hydrologic information from U.S. The four areas selected for the helicopter electromagnetic study, blocks A–D, have different geologic and hydrologic settings. The range of subsurface investigation is comparable to the depth of shallow groundwater. The map from each frequency represents a different depth of investigation for each area. The electromagnetic measurements were converted to electrical resistivity values, which were gridded and plotted on georeferenced maps. The electromagnetic sensor for the helicopter electromagnetic survey consisted of six different transmitter-receiver orientations that measured the earth's electrical response at six distinct frequencies from approximately 500 Hertz to approximately 115,000 Hertz. The objective of this project is to improve the understanding of the geohydrologic framework of the Arbuckle-Simpson aquifer. The helicopter electromagnetic and magnetic surveys were flown on March 16–17, 2007, in four areas of the Hunton anticline in south-central Oklahoma. This report is a digital data release for multiple geophysical surveys conducted in the Hunton anticline area of south-central Oklahoma.
