Data

This dataset contains results of generalized least-squares (GLS) regression for 136 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. GLS regression was used to relate drainage area, percentages of the drainage basins of the streamgages in...

We use the Dyngjusandur sandsheet, Iceland as a testbed to quantify the type of data necessary to accurately represent ventifact orientations and extract paleowind information through a statistical evaluation of the differences between photogrammetric based and in situ geological analysis. Forty representative ventifacts were selected for in situ measurement, 20 of which were imaged for

The Grand Calumet River flows through northwestern Indiana and was designated an EPA Area of Concern (AOC) in 1987. There are multiple legacy pollutants in the river including but not limited to heavy metals and PCBs. To investigate potential causes and patterns of eutrophication in the river, water samples were collected for 16S rRNA microbial and eukaryotic 18S rRNA amplicon sequencing...

These data are the geochemical (from X-ray fluorescence spectrometry), grain size, lithological (loss on ignition), diatom assemblages (taxa counts), bathymetric, and radioactive isotopes (210-Pb, 137Cs) from sediments from Wildcat Lake, Point Reyes National Seashore, California, USA starting in 2021. Taken together, they provide evidence for extreme precipitation events linked to...

This data release contains estimated monthly point-source nutrient loads for 97 municipal wastewater treatment plants, 20 industrial facilities, and 46 fish hatcheries and other aquaculture facilities that discharge within the watersheds draining to Puget Sound and the Strait of Juan de Fuca in Washington, or discharge directly to those water bodies. The data, which cover the years 2005...

Data include values obtained from files that were generated in the analysis of ATP levels from sperm derived from Common Carp. Data were obtained with by using an ATP-binding luciferase assay, whereby standard curves were generated and experimental samples were analyzed per day of standard curve generation. The luminescence intensities were recorded in relative light units (RLUs) and ATP

Reproductive condition of male fish is reflected by gonadal tissues and cell quality biomarkers. Common Carp from locations in the Lake Mead National Recreation Area in 2010 were collected, the biological characteristics of sperm and testicular tissues were analyzed from male fish. Raw data are provided in the form of flow cytometry files and other scored data from microscopy. Data are...

As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Breton Island, Louisiana (LA). During this study, multibeam bathymetry data were collected aboard the research vessel (R...

Particulate samples were collected from a fish hatchery in Puyallup, Washington, September 18 – 20, 2023 during late summer, low-flow conditions in the intake creek. Settled solids were collected from a retention pond and from the incubation room trough. The trough solids likely had been deposited during storm events the previous winter. A third sample was collected in the incubation...

Atmospheric particulate matter deposited to snow cover diminishes snow-surface albedo and results in early onset and rapid snow melting, challenging management of downstream water resources. We present here physical and chemical data from snow samples from 14 sites during the melt seasons of water years 2013-16 across 60,000 km2 of the central Rocky Mountains within the Upper Colorado...

These data were collected using distance sampling methods (point counts) and visual assessment of land cover and habitat at randomly selected locations in the Western Gulf Coastal Plain ecoregion of Texas and Louisiana in April-May 2017-2019.

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Elkins 30 x 60 minute quadrangle in Virginia and West Virginia. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2015 and 2021. The data were processed using...
