This dataset consists of 16 repeated magnetotelluric (MT) stations collected on Mount Tongariro, New Zealand, before (2009) and after (2013) the 2012 eruption. The data were collected in same locations with similiar instruments. Preeruption and posteruption electromagnetic magnetotelluric measurements determine variation in subsurface electrical properties resulting from changes in magmatic system associated with the 2012 eruptive cycle.

A detailed airborne gravity gradiometry, magnetic, and radiometric survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG). The high-resolution helicopter survey was flown at a flight-line spacing of 100 and 200 m, a flight-line azimuth of 70 degrees, a nominal flight-line elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at a 1-km interval with a flight-line azimuth of 160 degrees. Data were collected using a HeliFALCON airborne gravity gradiometry system, Scintrex CS-3 cesium magnetometer, Radiation Solutions RS-500 spectrometer, and Riegl LMS-Q1401-80n laser scanner and processed by CGG. Gravity gradiometry data include corrections for residual...

The U.S. Geological Survey (USGS) collected gravity data in the eastern Mojave Desert, California and Nevada as an aid to characterizing the regional geologic framework. Gravity stations were located between approximately lat 35°10’ and 35°50’ N. and long 115°05’ and 115°50’ W. and were distributed from west to east across parts of Shadow Valley, Clark Mountain Range, Mescal Range, Ivanpah Valley, Lanfair Valley, Bobcat Hills, and New York Mountains. Gravity data were ultimately tied to a World Relative Gravity Reference Network of North America gravity base station at Nipton, California (Jablonski, 1974) and supersede previously published data (Denton and Ponce, 2018). In general, gravity anomalies can be used...

A high-resolution airborne magnetic and radiometric survey of the southeast Mojave Desert, parts of California and Nevada was flown by EDCON-PRJ, Inc. from December 13, 2019 to March 21, 2020. The high-resolution fixed-wing survey was flown at a flightline spacing of 200 m, an azimuth of 70 degrees, a nominal elevation above ground of 100 m, and consists of about 17,277 line-kilometers. Tie lines were flown at a flightline spacing of 2 km with an azimuth of 160 degrees. Magnetic data were processed by EDCON-PRJ, Inc. and include corrections for diurnal variations of the Earth's magnetic field, magnetic field of the aircraft, tie-line leveled, micro-leveled, and an International Geomagnetic Reference of the Earth...
The Republic survey consists of high-resolution aeromagnetic and radiometric data designed to image the subsurface geology and structure of a large portion of northeastern Washington. These data are intended for rigorous modeling and interpretation of the geology and structure in this region and will be used to evaluate the potential for undiscovered resources and will contribute to USGS and Washington DNR-related mineral and geothermal resource assessments of the region. This release includes aeromagnetic and aeroradiometric data collected via low-altitude helicopter flown over northeastern Washington State, centered over the town of Republic, Washington. The data were acquired between September 26, 2022 and August...

This dataset consists of 24 magnetotelluric (MT) stations collected in 2017 in Gabbs Valley, Nevada. The U.S. Geological Survey acquired these data as part of Phase 2 of the Nevada Play Fairway Analysis Project led by the University of Nevada at Reno and funded by the Department of Energy (grant number DE-EE0006731) with support from the U.S. Geological Survey's Energy Program.
