These spatial and tabular data were compiled to have a decade-long record of the water usage in the riparian corridor and the wetlands near Phoenix, Arizona called the Tres Rios area to observe the effect of riparian and wetland health as characterized by vegetation greenness and its water use or evapotranspiration. The objective of our study was to quantify evapotranspiration (ET, in...

This dataset contains information from egg mass surveys conducted 2001-2024 by USGS monitoring Oregon spotted frog (Rana pretiosa) and Northern red-legged frog (Rana aurora) breeding counts, phenology, and embryo viability. Oregon spotted frog breeding surveys were conducted at 9 ponds in a restored meadow in Deschutes National Forest in Deschutes County, Oregon. Northern red-legged frog...

We deployed a sampler to characterize water quality from a household well tapping a shallow fractured dolomite aquifer in northeast Wisconsin. The sampler was deployed from January to May 2017, and monitored temperature, nitrate, chloride, specific conductance, and fluorescent dissolved organic matter on a minute time step; water was directed to sequential microbial filters during three...

Under the Great Lakes Restoration Initiative, the U.S. Geological Survey Mercury Research Lab (USGS MRL) conducted a multiyear assessment of mercury across the Laurentian Great Lakes. Biannual sampling was conducted across all five lakes onboard the U.S. Environmental Protection Agency (US EPA) research vessel Lake Guardian (in years 2010–2014, 2018) at pelagic sampling locations...

The GIS shapefile and summary table provide irrigated agricultural land-use for Hardee County, Florida through a cooperative project between the U.S Geological Survey (USGS) and the Florida Department of Agriculture and Consumer Services (FDACS), Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated land field-verified between...

The GIS shapefile and summary table provide irrigated agricultural land-use for Sarasota County, Florida through a cooperative project between the U.S Geological Survey (USGS) and the Florida Department of Agriculture and Consumer Services (FDACS), Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated land field-verified between...

This data release includes a shapefile of crop type parcels located in the Central Valley of California for the year 2020. These crop types were generated using Google Satellite Embeddings product as the sole input imagery and trained using labeled crop type data with a random forest classifier. There is a total of 9 different crop type classes.

This dataset contains an updated version of the catalog of tremor in south-central Alaska described in: Wech, A.G., 2016, Extending Alaska’s plate boundary—Tectonic tremor generated by Yakutat subduction: Geology, v. 44, no. 7, p. 587–590. [Also available at https://doi.org/10.1130/G37817.1.] The original catalog spans from 2007 to 2015, and the update extends tremor detection coverage...

Bathymetric, topographic, and grain-size data were collected in April 2019 along a 58.6 mile (94.3 kilometer) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 30, about 2.5 miles above South Canyon, and ends at river mile 88 at the upstream boundary of the Bright Angel Rapid (Phantom Ranch boat beach). This reach spans two...

The GIS shapefile and summary table provide irrigated agricultural land-use for DeSoto County, Florida through a cooperative project between the U.S Geological Survey (USGS) and the Florida Department of Agriculture and Consumer Services (FDACS), Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated land field-verified between...

This data release supports a pilot laboratory study evaluating the bioaccumulation and reproductive effects of dietary selenium on the endangered Topeka shiner (Notropis topeka). Adult fish were exposed under controlled flow-through conditions to three diets containing graded concentrations of seleno-L-methionine (control, 5.50, and 14.0 micrograms Se/g dry weight) to simulate...

Accurate age data is essential for modeling fish population dynamics and informing management decisions. Estimating age in cyprinid fishes like the invasive silver carp is challenging. During this study we evaluated precision and bias in age estimates of silver carp collected from the Illinois River, Illinois using seven structures: the first and second section of the ossified pectoral...
