Minimally processed AEM and magnetic data

Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2018 along 1,637 line line-kilometers over the western Hualapai Indian Reservation and surrounding areas. The survey was conducted as part of a study of the groundwater resources of the Truxton basin and Hualapai Plateau. The survey was designed to improve the understanding of the geometry of the major hydrostratigraphic contacts of the study area. Data were acquired by SkyTEM ApS with the SkyTEM 312 time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was flown at a nominal flight height of 30 meters (m) above terrain along block-style lines with a nominal spacing of 1 kilometer [...]
