Water, bed sediment, and biota were sampled in selected streams from Butte to near Missoula, Montana, as part of a monitoring program in the upper Clark Fork Basin of western Montana. The sampling program was led by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency.

Wildfire can impact soil-physical and soil-hydraulic properties, with major implications for hydrologic and ecologic response. The durations of these soil impacts are poorly characterized for some forested environments. This dataset sheds light on the first four years of recovery of soil-physical properties of bulk density, loss on ignition (measure of soil organic matter), and soil particle size distribution and of soil-hydraulic properties of sorptivity and field-saturated hydraulic conductivity.

These data were collected from the TOPGUN-SODA10 2AK core collected in 2010 by LacCore (University of Minnesota), the USGS. and the University of California (U.C.) Berkeley. The 8.9 meter length core had stable isotopes of oxygen and carbon sampled every 10 millimeters or so, and diatoms samples at every 50 millimeters to 200 millimeters depending on the depth in the core. mineralogic data were collected using X-ray diffraction and grain-size analysis were done at various depths. These data are used to interpret the Holocene and late Pleistocene hydrology and paleoclimate of the lake and the region. The interpretation can be found in: Rosen, M.R., Reidy, L., Starratt, S., Zimmerman, S., in review, Middle Holocene...

The dataset includes multiple file types (CSV, ArcGIS shapefiles, and images), data relates to the elemental analysis of fish otoliths. Otoliths examined in this study were from randomly-sampled individual Tidewater Goby (Eucyclogobius newberryi) and Prickly Sculpin (Cottus asper) from the adult population of Rodeo Lagoon and Rodeo Creek, Marin County, California. The fish were collected in April and August 2016.

These data contain concentrations of major and trace elements in quality-assurance samples.These are the machine-readable versions of Tables 2–5 from the U.S. Geological Survey Scientific Investigations Report, Distribution of Mining Related Trace Elements in Streambed and Floodplain Sediment along the Middle Big River and Tributaries in the Southeast Missouri Barite District, 2012-15 (Smith and Schumacher, 2018). Table_2 contains concentrations of major and trace elements in regular and replicate streambed-sediment samples in samples BR-02 and BR-04. Each sample was sieved and analyzed for concentrations within the less than 2-, less than 0.250-, and less than 0.063-mm size fraction. Averaged relative percent...

This data set contains example data for exploration of the theory of regression based regionalization. The 90th percentile of annual maximum streamflow is provided as an example response variable for 293 streamgages in the conterminous United States. Several explanatory variables are drawn from the GAGES-II data base in order to demonstrate how multiple linear regression is applied. Example scripts demonstrate how to collect the original streamflow data provided and how to recreate the figures from the associated Techniques and Methods chapter.

The Fort Stanton-Snowy River cave system (FSC) is located in Lincoln County, New Mexico in the upper Rio Hondo Basin. The entrance of the cave is on Bureau of Land Management (BLM) land near the site of historic Fort Stanton. In 2001, the Snowy River Formation was discovered. This formation, a white calcite deposit that lines a streambed within the cave, is now considered to be the largest cave formation in the world. Initially thought to be hydrologically inactive, the Snowy River passage has intermittently flooded in response to large precipitation events such as the passage of Hurricane Dolly in 2008 and a large spring snowmelt runoff in 2010. There is interest in determining the source of the water that flows...

The southeastern United States was modeled to produce 59 simulations of historical and potential future streamflow using the Precipitation Runoff Modeling System (PRMS) as part of the study documented in LaFontaine and others (2019). One simulation used historical observations of climate, 13 used historical climate simulations using statistically downscaled general circulation model (GCM) output from the Coupled Model Intercomparison Project (CMIP5), and 45 used potential future climate simulations using statistically downscaled CMIP5 GCMs for four representative concentration pathways. Historical simulations with observations are for the period 1952-2010, historical simulations with the GCMs are for the period...

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Water quality data were collected using an Ecomapper Autonomous Underwater Vehicle (AUV) and measured parameters include temperature, specific conductance, salinity, water density, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named AUV_WQ_South.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting of a group of files that have been compressed into a zip archive that is named AUV_WQ_South_shapefile.zip.

This data release comprises a set of environmental sucralose occurrence data in the Sacramento area. Groundwater samples were collected throughout the Sacramento Valley as part of the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project study in the Sacramento area. These water samples were analyzed for sucralose by chemical derivatization followed by gas chromatography mass spectrometry. The calculated concentrations of sucralose detected in the water samples and the associated quality assurance data are tabulated in this data release. This data release supports the following publications: [Voss et al, in prep]
