Relative-gravity differences from the 2014 Minute 319 Pulse Flow in the Colorado River Delta

Data are drift-corrected relative gravity differences between stations. Drift correction was carried out by modeling drift as a continuous function of time using polynomial or locally-weighted scatterplot smooth (lowess) curves. The process and software for carrying out drift correction is described in the USGS Arizona Water Science Center QA/QC plan for relative gravity data collection.

Gravity Change from 2014 to 2015, Sierra Vista Subwatershed, Upper San Pedro Basin, Arizona

Relative-gravity data were collected at 58 stations over ten days between May 27, 2015 and June 25, 2015 using a Zero Length Spring, Inc. Burris relative gravity meter (mention of a particular trade name does not imply endorsement by the U.S. Governement). In total, 179 relative-gravity differences were observed. Relative-gravity-meter drift was removed from the observations by modeling drift...

Electromagnetic induction tabular data from the 2014 Minute 319 Pulse Flow in the Colorado River Delta

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.

DC resistivity data files from the 2014 Minute 319 Pulse Flow in the Colorado River Delta

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,...

Geophysical Data from the 2014 Minute 319 Pulse Flow in the Colorado River Delta

Geophysical methods were used to monitor infiltration during a pulse flow release of water in the Colorado River delta in Mar-May 2014. Electromagnetic-induction methods were used at 14 transects in the limitrophe reach of the River between the U.S. and Mexico, and further south in Mexico. These data are sensitive to variation in soil texture and water content. The repeat direct-current...
