Better Subsurface Mapping Seen With New Gravity Sensor.

The article informs about quantum gravity surveying instrument, developed by Michael Holynski, the University of Birmingham's head of atom interferometry, can potentially produce Google-type maps of the subsurface the instrument negates the effects of vibrations and other disturbances. It mentiosn that the instrument interferometry to compare the paths to reveal local differences in gravitational fields, mapping the subsurface and identifying signal noise to be removed from readings.
