Speaking of Albuquerque, this just-published paper shows how measuring the change in acceleration due to gravity can be used to map aquifer storage change. Importation of San Juan River water has made a big difference.

Microgravity surveying is great for this and other geo applications. I know of many geothermal fields mapped the same way to monitor fluid level and steam migration. Good stuff!
