Progress 10/01/10 to 09/30/11
Outputs
OUTPUTS: Precision Gravimetry Sensing: Gravimetry is the measure of gravity variations that result from density variations in the earth's crust. In a manner similar to an X-ray of the human body, these minute variations, when cast into an image format, can provide a great deal of insight into the subsurface structural makeup. Accelerometers measure differences between translation-induced motion and gravity. PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
Impacts
The developed gravimetry methodology is currently being utilized to map groundwater variation from the air; this is being done by correlating the gravity signal with the water table.
