WebAug 27, 2014 · The above discussion points to the fact that it is important to separate regional and residual gravity anomalies. In effect, regional and residual gravity … The Bouguer, free-air, and isostatic gravity anomalies are each based on different theoretical corrections to the value of gravity. A gravity survey is conducted by measuring the gravity anomaly at many locations in a region of interest, using a portable instrument called a gravimeter. See more The gravity anomaly at a location on the Earth's surface is the difference between the observed value of gravity and the value predicted by a theoretical model. If the Earth were an ideal oblate spheroid of uniform density, … See more The gravity anomaly is the difference between the observed acceleration of an object in free fall (gravity) near a planet's surface, and the corresponding value predicted by a model of the planet's gravitational field. Typically the model is based on See more • Gravimetry • Gravity anomalies of Britain and Ireland • Magnetic anomaly • Mass concentration (astronomy) • Physical geodesy See more The starting point for the model field is the International Reference Ellipsoid, which gives the normal gravity gn for every point on the Earth's … See more Lateral variations in gravity anomalies are related to anomalous density distributions within the Earth.
