Airborne electromagnetic and magnetic geophysical survey data of the Yukon Flats and Fort Wainwright areas, central Alaska, June 2010

Study to estimate the 3-D distribution of permafrost, to evaluate the effectiveness of these methods at mapping permafrost geometry, and to better define the physical properties of the subsurface in discontinuous permafrost areas.

Airborne electromagnetic data and processing within Leach Lake Basin, Fort Irwin, California

Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution.

Airborne geophysical surveys conducted in western Nebraska, 2010: contractor reports and data

Three contractor reports and data files for an airborne electromagnetic survey describing data aquisition and processing. Processed geophysical data were inverted to produce resistivity depth sections along flight lines. Results are described herein.

Digital data from the Great Sand Dunes airborne gravity gradient survey, south-central Colorado

Flight-line data and gravity grids with documentation.

Digitized data from ground geophysical surveys in Afghanistan

Surveys originally carried out by Soviet geophysicists from 1972 through 1974 were digitized. Georeferencing was problematic as were some of the measured characteristics; we explain what we did and how we have understood these data.

Gravity anomaly grids for the conterminous US

Measurements of the gravitational field vary slightly from place to place due to the composition and structure of Earth's crust. Includes the isostatic and Bouguer anomalies for the conterminous US.

Helicopter Electromagnetic and Magnetic Geophysical Survey Data for Portions of the North Platte River and Lodgepole Creek, Nebraska, June 2008

The objective of the survey was to improve the understanding of the relationship between surface water and groundwater systems critical to developing management programs for water resources.

Radiometric Survey in Western Afghanistan: A Website for Distribution of Data

Radiometric (uranium, thorium, potassium content and gamma-ray intensity) and related data were digitized from radiometric and survey route location maps of western Afghanistan previously published by others in 1976.

Surface mineral maps of Afghanistan derived from HyMap imaging spectrometer data, version 2

The report presents new maps from data collected in 2007 and the processing steps applied to that data. The maps are being used for natural resource development and to prioritize study areas of mineral distribution to assist with economic revitalization.

Terrestrial radioactivity and gamma-ray exposure in the United States and Canada

Flight-line databases and derived grids from aeroradiometric surveys across the US carried out during the 1970s
