Data

This dataset includes measurements of biological and physical attributes of five restored tidal wetlands in the San Francisco Bay Estuary. All marshes were restored in the last 30 years, from the late 1990's to the early 2010's, and are located between San Pablo Bay in the north to the South Bay Salt Ponds in the south. Biological attributes measured include plant species presence...

Clear Lake is a 180 km2 freshwater lake located approximately 120 km northwest of Sacramento in the California Coast Range. The lake is a popular sport-fishing destination, however, there are fish consumption advisories associated with mercury (Hg) contamination for several species. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower...

This dataset contains vertical water-quality profiles of the Hudson River collected over two field seasons from May through October 2023 and May through September 2024. Data were collected at 27 equidistant transects along the lower Hudson River from Troy to Riverdale, NY using a stratified random sampling design. Each month, a single sampling location was randomly selected along each...

From 2019 to 2021, sixty age 0 herring were collected and tested for infection with viral haemorrhagic septicemia virus and viral erythrocitic necrosis virus from Port Angeles Harbor in WA, USA. This dataset describes the prevalence and intensity of infection with both pathogens. Then a series of laboratory experiments were conducted to determine how the epizootics of the two pathogens...

We used visual encounter surveys (VES) and environmental DNA (eDNA) surveys for amphibians in the western united states. Data are results of both VES and eDNA surveys for all amphibian species that occur in the locations surveyed.

The twin Voyager 1 and Voyager 2 spacecraft launched in August (Voyager 2) and September (Voyager 1) of 1977 and reached the Jupiter system in March (Voyager 1) and July (Voyager 2) of 1979, where they acquired images of the Galilean satellites before continuing on to Saturn. Each spacecraft was identically equipped with both wide-angle and narrow-angle slow-scan vidicon cameras that...

The monitoring of Lake Saint Clair Metropark beach involved several types of data collection. This data release includes data sets for the counts of avian species (gulls and Canada geese) and data on water fluxes between surface water and groundwater measured during recreational seasons of 2021, 2022, and 2023.

This dataset provides wave, water level and non-tidal residual (NTR) timeseries for a reanalysis period and future projections for the mid-century. Data are available at nearshore stations across the Salish Sea and are packaged by county. Data support coastal Storm Modeling System (CoSMoS) scenarios and available for a multiple sea-level conditions (0 - 3 m).

To assess the spatial and temporal hydrographic variability along the West Florida Shelf (including Tampa Bay and Charlotte Harbor), stable oxygen (d18O) and hydrogen (dD) isotope ratios were measured using water samples collected from across the region by the U.S. Geological Survey (USGS) and collaborators. Surface, bottom, and groundwater samples from a marine well network along the...

This data release contains the concentration and quality assurance results for 30 streams, sampled twice. In 2023, the typology sampled was Pennsylvania and Maryland Piedmont mixed agriculture. Each dataset consisted of 30 sampling sites. Samples were analyzed for the following constituent classes (count of constituents); field and water-quality parameters (9), nutrients/anions (13)...

This data release contains the concentration and quality assurance results for 29 streams, sampled twice, and 1 stream, sampled once, in the Chesapeake Bay Delmarva row crop region (Maryland and Delaware, USA) for the following constituent classes (count of constituents); field and water-quality parameters (9), nutrients/anions (13), dissolved organic carbon (1), per- and polyfluoroalkyl

The U.S. Geological Survey conducted a study in Milwaukee, Wisconsin, to evaluate the performance of a biofilter designed to treat urban stormwater runoff from a roadway. This data release includes load calculations for total suspended solids, nutrients, major ions, and 12 metals for monitoring that ran from March, 2022 to November, 2024. Loads are reported for both the inlet (USGS site...
