Electromagnetic induction data For the Minute 319 pulse flow, electromagnetic induction surveys were carried out jointly by the USGS and UABC-CICESE. Measurements were made at 5 m intervals and transect lengths ranged from 55 m to 200 m.

Data are provided in tabular (csv) and vector (shapefile) formats with one row per station.Relative-gravity surveys were carried out using a ZLS Coporation Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations, or between absolute-gravity stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The vertical gravity gradient was assumed to be -3 microGal/cm at each absolute-gravity site. Relative-gravity...

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 the following: (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 Kennedy, J.R., 2016, Gravity change from 2014 to 2015, Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona: U.S. Geological Survey Open–File Report 2016–1155, 15...

Sierra Vista, AZ, Southwest Gravity Program, USGS Science Data Catalog (SDC), gravity, groundwater, hydrogeophysics, Fewer tags DC resistivity data Time-lapse DC resisitivity data were collected to monitor water table position during the 2015 Lower Coloradro River Pulse Flow. Resistivity data are sensitive to water-content change in the subsurface. DC resistivity data were collected at three transects. In the U.S., one transect was located parallel to the channel in the southern limitrophe reach nearby a streamgaging station. In Mexico, two transects were measured, one parallel and one perpendicular to the channel.
