Acute (96-h) and chronic (14-d) toxicity of uranium pond water, before and after zero-valent iron treatment, was evaluated using the mayfly Neocloeon triangulifer. Water chemistry data characterizing the laboratory-synthesized waters used in the experiment include specific conductance, pH, alkalinity, major-ion, and metal concentrations. Water quality data collected from the test waters...

This data release contains Adirondack stream chemistry data collected by the New York State Department of Environmental Conservation Rome, NY field station between 1979 and 2001. These data were previously unpublished or only summarized in associated New York State reports and peer-reviewed journal articles.

Sediment hosted zinc (Zn) and lead (Pb) deposits are the most significant sources of zinc and lead ore globally. Zinc is required to create corrosion-resistant iron and steel products among other applications, and lead is an important element in car batteries and other industrial products. These deposits can also contain significant quantities of silver (Ag), which is commonly used in...

Winter body condition is an important driver of survival, reproductive output, and overall population health in waterfowl. Diving duck species utilize distinct habitats, exploit unique resources, and can collectively provide an integrated index of winter habitat quality. The San Francisco Bay (SFB) is the largest estuary on the west coast of North America, serving as critical wintering...

Measuring the spatial and temporal patterns of tidal marsh sediment deposition builds our understanding of how physical forcing (tidal flooding and waves) and sediment availability interacts with the marsh. We deployed sediment pad filter traps in twelve shore-normal transects across the Eden Landing Ecological Reserve tidal marshes and restorations in south San Francisco Bay, CA...

The USGS Metadata Wizard is a desktop application to create and edit XML metadata records that describe data products. The tool creates metadata in the Content Standard for Digital Geospatial Metadata (CSDGM) format, as endorsed by the Federal Geographic Data Committee (FGDC). Users can populate an XML metadata record by entering information in the form-based user interface, or by...

This data release provides phytoplankton environmental DNA (eDNA) data from 19 sites in 12 different streams within the Milwaukee Metropolitan Sewerage District Planning Area in and around Milwaukee, WI. These streams include the Milwaukee River, the Kinnickinnic River, the Menomonee River, and more. Phytoplankton composition was determined using eDNA sequencing techniques. Data were...

This data release provides the full analytical dataset for fourteen new argon‑argon (⁴⁰Ar/³⁹Ar) radiometric ages from olivine tholeiite basalt flows at the Idaho National Laboratory (INL) on the eastern Snake River Plain, Idaho. Samples were collected from basalt flows in eight subsurface coreholes (43–450 ft below land surface) and five surface sites. The release includes machine...

Radiometric data (gamma ray spectrometry) were collected via a small uncrewed airborne system (sUAS) in June 2024 to characterize four distinct mine waste features in Southwestern New Mexico. Walking surveys with a handheld meter were also conducted over parts of the survey areas to provide ground truth checks for the airborne data. Survey sites and their respective areas covered include...

This dataset provides geochronologic data for selected metasedimentary rock samples from the Lane Mountain area about 20 kilometers northeast of Barstow, California and the western base of the Inyo Mountains about 20 to 30 km northeast to north of Lone Pine, California. Data are reported for 2 detrital zircon samples from the Lane Mountain area and 3 detrital zircon samples from the Inyo...

This dataset contains estimated probabilities of detecting at least of n zero days of streamflow for river locations across the contiguous United States as a function of drainage area. Also included are the 95-percent confidence intervals around the probability estimates. Probabilities are estimated by survival regression models, which are simple, non-parametric, empirically-based models...

The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 7-mile reach of the Middle Green River at Horseshoe Bend near Jensen, Utah. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al., 2021)...
