USGS scientists enumerated bacteria, including bacterial pathogens, from surface water and sand/sediment collected at an intertidal site (mudflat) near the outfall the Palo Alto Regional Water Quality Control Plant (RWQCP). This site has been monitored for metal concentrations and benthic invertebrate community for the last 30 years. Continued efforts to document changes in pollutant

This dataset contains 3,229 feather files with time series of all model inputs for machine learning models predicting streamflow drought across the conterminous United States (CONUS). Files contain weekly time series of streamflow percentiles, meteorology, snow water equivalent, forecast meteorology, estimated water use, soil moisture, as well as lagged versions of these datasets. Values...

In collaboration with researchers at the University of Puerto Rico, Mayaguez, the U.S. Geological Survey acquired multimethod surface seismic imaging data at 21 sites in Puerto Rico for shear-wave velocity site characterization. These data were collected at both permanent and temporary seismograph stations throughout the island, between March 6 and March 18, 2022. Data were acquired...

For evaluating and retrofitting existing buildings to resist earthquakes, the 2023 ASCE/SEI 41 Standard provides Basic Safety Earthquake spectral response accelerations at four levels (BSE-1N, BSE-2N, BSE-1E, and BSE-2E). This data release covers BSE-1E and BSE-2E spectral response accelerations for sites outside of the conterminous United States. For sites in the conterminous U.S., BSE...

Zooplankton samples were collected in the summer/fall of 2024 at multiple sites in the Sacramento River, Yolo Bypass, and Cache Slough Region of California and analyzed for a suite of 160 current-use pesticides and pesticide degradates by the U.S. Geological Survey Organic Chemistry Research Laboratory. Samples were collected at two sites in the Bypass, at a comparison site on the...

This dataset contains morphometric and isotopic data for American alligators (Alligator mississippiensis) that were sampled from within four freshwater (FW) wetlands and one estuarine (EST) wetland within the Greater Everglades ecosystem. Due to their compartmentalization and varied habitat and water regimes, there were multiple sampling sites within two of the FW wetlands. The five...

The dataset provides access to all data used in the interpretation of results for the study including dose response curves from toxicity tests, predicted minimum lethal concentration data, water quality data, and mortality data.

This data contains the mean and standard deviations for movement rates for silver carp in the upper Mississippi River 2014 and 2021. The data are summaries of the posterior distribution from a Bayesian multistate model described in Stanton et al. 2024 (https://doi.org/10.7717/peerj.17834). References: Stanton JC, Brey MK, Coulter AA, Stewart DR, Knights B. 2024. Bayesian multistate...

This data release contains a set of 21st-century burned-area projections to explicitly account for fire-fuel feedbacks in boreal North America for the years 2010 - 2100. Wildfire regimes in the boreal forest biome of North America are vulnerable to shifts in climate, and significant intensifications in area burned are anticipated under many 21st-century global climate model (GCM)...

This dataset includes measurements of shell properties (e.g. density, volume, and weight) of the ostracode species Paracyprideis pseudopunctillata (subphylum Crustacea), which inhabits the continental shelves of the Arctic Ocean. Using microfocus X-ray computed tomography (microXCT) scans, we generated detailed morphometric measurements of specimens collected from both surface and down...

Information concerning the availability, use, and quality of water in the 64 parishes of Louisiana is critical for water-supply management. In cooperation with the Louisiana Department of Transportation and Development, the U.S. Geological Survey (USGS) Lower Mississippi-Gulf (LMG) Water Science Center (WSC) has been collecting, compiling, and publishing water-withdrawal and water-use...

This data release provides Geologic Map Schema (GeMS)-compliant GIS data for new geologic mapping of the Bison Range and surrounding area on the Flathead Reservation, northwestern Montana. The database represents the geology for the 150 square kilometer, geologically complex map area, at a publication scale of 1:24,000. The map covers parts of Sanders and Lake Counties, Montana. All...
