Recent developments in digital gravity data acquisition on land

Abstract

Land gravity meters have traditionally been analog, with readings carried out and transcribed manually. The precision (theoretically 10–50 μGal) and the observation rate are very dependent on the skill of the observer. However, the advent of digital recording meters, now offered by several commercial firms, has automated much of the work. As a result, land gravity surveying is both faster and more accurate than in the past and can now be applied to problems where it previously was of little help.
