Utah FORGE: TEM and Gravity Data


This submission includes a gravity data in text format and as a GIS point shapefile and transient electromagnetic (TEM) raw data. Each text file additionally contains location data (UTM Zone 12, NAD83) and elevation (meters) data for that station.

The gravity data shapefile was in part downloaded from PACES, University of Texas at El Paso, http://gis.utep.edu/subpages/GMData.html, and in part collected by the Utah Geological Survey (UGS) as part of the DOE GTO supported Utah FORGE geothermal energy project near Milford, Utah. The PACES data were examined and scrubbed to eliminate any questionable data. A 2.67 g/cm^3 reduction density was used for the Bouguer correction.

The attribute table column headers for the gravity data shapefile are explained below. There is also metadata attached to the GIS shapefile.

name: the individual gravity station name.
HAE: height above ellipsoid [meter]
NGVD29: vertical datum for geoid [meter]
obs: observed gravity
ERRG: gravity measurement error [mGal]
IZTC: inner zone terrain correction [mGal]
OZTC: outer zone terrain correction [mGal]
Gfa: free air gravity
gSBGA: Bouguer horizontal slab
sCBGA: Complete Bouguer anomaly
