Eotvos correction gravity

WebWhat is the aim of the correction of gravity measurements to obtain Bouguer gravity anomaly? Corrections. Gravity requires many corrections in order to adjust the observed value of gravity to an absolute value and to take the effects of topography, terrain, elevation, motion, and other factors into account. WebEötvös correction: typically associated with shipborne or airborne surveys; where v is the speed (kph), l is the latitude and a is the direction of travel (measured clockwise) Topography correction: 1) Free-air correction: need for position in spave of the gravimeter (affected by a rise in cm’s)
