Gravity Change from 2014 to 2015, Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona
Relative-gravity data and absolute-gravity data were collected in the Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona, in May-June 2014 and 2015. Data from 2014 and a description of the survey network were published in USGS Open File Report 2015-1086. Data presented in the shapefile here are:
1) Network-adjusted values from 2015,
2) Gravity change from 2014 to 2015, and
3) Survey-grade coordinates obtained from a Global Positioning System (GPS) survey in 2015.
2015 data and network adjustment results are presented in

Gravity change from 2014 to 2015, Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona
Relative-gravity data and absolute-gravity data were collected at 68 stations in the Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona, in May–June 2015 for the purpose of estimating aquifer-storage change. Similar data from 2014 and a description of the survey network were published in U.S. Geological Survey Open-File Report 2015–1086. Data collection and network adjustment results are prAuthorsJeffrey R. KennedyGravity data from the Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona
Observations of very small changes of Earth’s gravitational field (time-lapse gravity) provide a direct, non-invasive method for measuring changes in aquifer storage change. An existing network of gravity stations in the Sierra Vista Subwatershed was revised in 2014 to better understand the spatial distribution of changes in aquifer storage, especially with relation to ephemeral channel recharge aAuthorsJeffrey R.
