Measures of the vulnerability of runoff to drought during 2015 in the western United States
Measures used to assess the vulnerability of streamflow in 326 river basins to the 2015 drought in the western United States.
Geospatial datasets and model for the flood-inundation study of the North Fork Kentucky River at Hazard, Kentucky
Digital flood-inundation maps were created for a 7.1-mile reach of the North Fork Kentucky River at Hazard, Kentucky. The flood-inundation maps, which can be accessed through the U.S. Geological Survey (USGS) Flood Inundation Mapping Science website at https://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (st
Geochemical and geophysical data for wells in the Fruitvale and Rosedale Ranch oil and gas fields, Kern County, California, USA
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed data for the purpose of mapping groundwater salinity in selected oil and gas fields in California. The data for the Fruitvale and Rosedale Ranch oil fields include well construction data, digitized borehole geophysical data, geochemical analyses of water samples from oil a
Audiomagnetotelluric sounding data, stations 1-9, Taos Plateau Volcanic Field, New Mexico, 2009
This dataset includes the audio-magnetotelluric (AMT) sounding data collected in 2009 in and near the San Luis Basin, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including AMT surveys, in the San Luis Basin to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aq
Sediment and geomorphology data for Walnut Creek, Iowa
This data release consists of 9 comma-delimited ascii files that contain 1) ten-minute discharge values, 2) mean daily discharge and computed sediment loads, 3) grain size percentiles, 4) radionuclide source sample results, 5) radionuclide target sample results,6) laboratory sample splits, 7) elemental analysis results of samples, 8) suspended-sediment measurements, and 9) turbidity measurements.
Data Sets for the actual evapotranspiration (AET) rates from 2000 to 2017 in east-central and northeast Florida basins calculated using water-budget balance analysis (WBA), the Simplified Surface Energy Balance Operational (SSEBop) method, and the land-co
Average annual Actual Evapotranspiration (AET) rates for basins in east-central and northeast Florida from 2000 to 2017 were calculated using a water-budget balance equation. These AET rates are used to assess the reliability of the AET rates calculated using the Simplified Surface Energy Balance operational (SSEBop) method. The AET annual rates, from 2000 to 2017 for the Simplified Surface Energy
Mercury injection capillary pressure data in the U.S. Gulf Coast Tuscaloosa Group in Mississippi and Louisiana collected 2015 to 2017
This data release contains mercury injection capillary pressure (MICP), pseudo-wetting saturation, and carbon dioxide (CO2) column height data for subsurface Tuscaloosa Group samples from Mississippi and Louisiana.
MODFLOW-2000 and MODPATH models for simulations used to delineate contributing areas for 2017 pumping conditions to selected wells in Ingham County, Michigan: U.S. Geological Survey data release
A regional groundwater flow model (https://pubs.usgs.gov/sir/2009/5244/) was updated to reflect 2017 pumping conditions in the Tri-County Region covering most of Clinton, Eaton, and Ingham Counties, Michigan. This model was developed to simulate the regional hydrologic system in Tri-County area and continues to be used for planning and protection of area water supplies. Revised contributing area d
Bathymetry and acoustic backscatter data collected in 2007 from the San Miguel Passage in the Channel Islands, California
Bathymetry and acoustic backscatter data were collected in the San Miguel Passage, Channel Islands, California in August 2007 by the U.S. Geological Survey, Pacific Coastal and Marine Science Center. Data collection was conducted aboard the ship R/V Shearwater as part of the USGS research cruise S-2-07-SC. The San Miguel Passage is within the Channel Islands National Marine Sanctuary, and is the b
Field portable X-ray fluorescence and associated quality control data for the western Mojave Desert, San Bernardino County, California
These data on the concentrations of 27 selected elements were collected using a field portable (handheld) X-ray fluorescence (pXRF) instrument (Groover and Izbicki, 2016) equipped with a 4-watt Ta/Au X-ray tube on samples of 1) surficial alluvium, 2) rock, and 3) archived core material and drill cuttings from monitoring wells across an approximately 14,300 square kilometer area in the western part
Laboratory quality-control data associated with samples analyzed for microbiological constituents at the Ohio Water Microbiology Laboratory, 2012-2017
This dataset contains data tables of laboratory quality-control data associated with environmental samples analyzed for microbiological constituents at the Ohio Water Microbiology Laboratory of the U.S. Geological Survey (USGS) during federal fiscal years 2012-2017 (October 1, 2011 through September 30, 2017). The environmental samples were collected across the United States by the USGS National W
Annual California Sea Otter Census-2018 Spring Census Summary
The spring 2018 mainland sea otter count began on April 26, and was completed by May 24, 2018. Overall viewing conditions this year were good and rounded off to the same conditions experienced during the 2017 spring census (View Score 2.4, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent). The surface canopies of kelp (Macrocystis sp.) were considered by most participants to be above nor
