Researchers explore possibilities of microgal gravimetry

Abstract

Microgal gravimetry's unique ability to sense mass anomalies and movements beneath the surface of the Earth makes it a promising technology for science and engineering, particularly when it is used with Global Positioning System geometrical measurements. It is rapidly becoming the method of choice for measuring postglacial rebound, monitoring active volcanoes, modeling subsurface cavities, detecting changes in aquifers, and studying changes in the Arctic and Antarctic ice masses. More than 50 scientists and students from 14 nations recently met at a Chapman Conference to discuss microgal gravimetry and its applications.
