Description: The following geophysical data layers are included in this service:
Merged Aeromagnetic Total Field Anomaly Map"The Wyoming aeromagnetic map is constructed from grids that combine information collected in 27 separate aeromagnetic surveys conducted between 1950 and 1997."Complete Bouguer Gravity Anomaly Map
"The complete-Bouguer gravity anomaly grid was compiled using data from over 23,622 gravity stations in and adjacent to the state of Wyoming. These data were extracted from the gravity data base maintained by the National Geophysical Data Center (from Department of Defense unclassified data) (Hittleman and others, 1994) and augmented with data from the USGS and from several university theses and dissertations."
Isostatic Gravity Anomaly Map
"The colors on this isostatic gravity map reflect variations in the Earth's gravity field caused primarily by lateral variations in density in the rocks that make up the upper part of the Earth's crust. An isostatic gravity grid was derived from Bouguer and free-air gravity anomaly data. This grid was created by removing from the Bouguer gravity grid a model of the gravity expression caused by deficiencies in mass (compensating mass) that supports topographic loads."
Data downloaded from USGS have in some cases been minimally modified (e.g., clipped to spatial extent, projected, shaded) but have not been formally reviewed or altered by the WSGS. Users are encouraged to visit the USGS data release to download the original dataset.
