The U.S. Geological Survey (USGS) is doing a series of studies of the Española
Basin in northern New Mexico. One objective of these studies is to understand
the hydrogeologic framework of the Española Basin to help land managers
plan and develop water supplies. These studies involve a multidisciplinary
approach to better understand the critical aquifers in the intracontinental
rift environment. Detailed geologic mapping, high-resolution airborne
magnetic surveys, electromagnetic surveys, and hydrologic, lithologic,
and hydrogeochemical data are being used to better understand the aquifer
systems in the Española Basin. A magnetotelluric (MT) survey was done
as part of these studies. The primary purpose of the MT survey was to
map changes in electrical resistivity with depth that are related to
lithologic variations important to the critical aquifers. The purpose
of this report is to release the MT sounding data; no interpretation
of the data is included.
