Salient Characteristics PR #0040(TO BE ADDED)
S15059
The USGS Water Science Center in Albuquerque, NM needs to purchase one (1) relative gravity meter and shipping case. This equipment is intended to be used for investigating changes in groundwater storage and determining aquifer properties. This equipment will be used to make repeat measurements of gravity at selected sites. The difference in gravity between successive measurements will be a measure of change in the mass of water present in the subsurface at the site. This equipment needs to be compatible with existing gravity equipment and knowledge in the Arizona WSC. AWSC personnel will be training NMWSC personnel for use of the equipment and how to make calibration measurements using relative gravity meter.
