Length: 00:01:41

Location Taken: Tucson, AZ, US


The Southern Avra Valley Storage and Recovery Project

Here, Tucson recharges 60,000 acre-feet of water ech year (that's 74 billion kg)

That much mass changes the local gravity field

We installed gravity meters to measure that change

Other meters were also used to measure the gravity change
