Gravity data from the Truxton area, northwestern Arizona, tabular format
This dataset represents the network-adjusted results of relative- and absolute-gravity surveys. 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...
Water Quality Parameters in the Verde River below Granite Creek, Arizona, June 2018
Water quality parameters (water temperature, specific conductance, pH, dissolved oxygen, air temperature, and barometric pressure) were measured in the Verde River over a half mile reach below the confluence with Granite Creek. Measurements were made using a calibrated In-Situ SmarTROLL multiparameter meter on June 13, 2018.
Carbon and Strontium Isotopic Data for Rock, Soil, and Soil Gas from the Big Chino Sub-Basin, Arizona 2017 and 2018
Dataset includes rock and soil gas carbon and strontium values. Soil gas samples were collected from different depths in augered soil core holes. Material at the bottom of the soil core hole was analyzed in addition to soil gas for some samples. Rock samples were collected from outcrop locations as well as from drill cuttings.
Absolute gravity data from Pinal County, Arizona, 2019
This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) in 2019 in Pinal County, Arizona. Measurements were made at a total of 19 different stations used by the Arizona Department of Water Resources (ADWR) to monitor aquifer-storage changes. Data are presented in tabular and spatial vector (point) form, including rele
Soil-Water Balance Groundwater Recharge Model Results for the Lower Colorado River Basin
This USGS Data Release represents Soil-Water Balance (SWB) groundwater infiltration modeling results for the Lower Colorado River Basin (LCRB).
The data release was produced in compliance with 'open data' requirements as a way to make the scientific data associated with USGS research efforts and publications available to the public.
There are 3 separate groups of datasets associ...
Controlled source audio-frequency magnetotellurics (CSAMT) data from the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, Arizona
Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Grand Canyon West and Plain Tank Flat areas of the western Hualapai Reservation, Arizona, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) g
Repeat microgravity data from the Big Chino Subbasin, 2001-2017, Yavapai County, Arizona
This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) between 2009 and 2017 in the Big Chino Subbasin, Yavapai County, Arizona. Measurements were made about 3 times per year at a total of 33 different stations. Data are presented in tabular form, including relevant parameters used for processing. Data were output by g sof
Repeat microgravity data from Tucson Basin and Avra Valley, Arizona, 2016-2019 (ver. 2.0, August 2019)
This dataset supercedes an earlier data release and includes all previous data in addition to data from 2019. These data represent the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Micro-g LaCoste D-series relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift...
Spatial and temporal variability of peaks and seasonal maximum flows in the Conterminous U.S. from cluster analysis of standardized streamflow obtained from the USGS National Water Information System
This dataset contains annual peak and seasonal maximum streamflow data from the USGS National Water Information System (NWIS) and the results of an analysis of spatial and temporal patterns for those data for the conterminous U.S. An interpretation of the analysis of these data will be published in a journal article. The streamflow data were compiled for the years 1966 to 2015 for 415 streamg...
09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 07/28/2017 Manning's n Verification
Continuous slope-area (CSA) sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. Stage data were recorded by submersible pressure transducers at each of the four cross sections, which is used to compute channel roughness using the known discharge measured by Flume 6.
09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 07/28/2017 Continuous Slope-Area
Continuous slope-area (CSA) sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. A flow event occurred on July 28, 2017. Stage data were recorded by submersible pressure transducers at each of the four cross sections. The stage data, along with cross section geometry and fie
09471143 - Walnut Gulch below ARS Flume 6, near Tombstone, AZ - 08/02/2017 GPS Survey
Continuous slope-area sensors are installed at four cross sections downstream from Flume 6 operated by the Agricultural Research Service (ARS) at the Walnut Gulch Experimental Watershed. The CSA reach was installed to test the CSA method and determine channel roughness using the known discharge measured by Flume 6. A flow event occurred on July 28, 2017. A GPS survey was conducted on August...
