    LECTURE 4: GRAVITY ANOMALIES AND ISOSTASY Average gravity on the Earth’s surface is about g= m/s2, and varies by ~ mgal (about % of g) from pole to equator. (1 mgal= m/s2) Gravity anomalies are local variations in gravity that result from topographic and subsurface density variations, and have amplitudes of several mgal and Size: 1MB.

    filtered data of gravimetric anomaly, the gravity maps of filtered data for wavelengths greater than 50 km were built. The spatial derivatives and Fourier transforms, where needed, were computed using Hildenbrand’s () software. The two programs from the package of Phillips () used to compute the local estimates are LOCAL and LOCDEP.

    Summary. GGMplus (Global Gravity Model plus) is a composite of GRACE and GOCE satellite gravity, EGM and short-wavelength topographic gravity effects at about m resolution for all terrestrial and near-coastal areas of the Earth between ±60° latitude.

These gravity maps are part of a folio of maps of the Tonopah 1 degree by 2 degrees quadrangle, Nevada, prepared under the Conterminous United States Mineral Assessment Program. Each product of the folio is designated by a different letter symbol, starting with A, in the MF folio.

The quadrangle encompasses an area of ab km2 in the west central part of Nevada. This digital grid describes the Bouguer gravity anomaly for the conterminous US.
