Patuxent Box Turtle Study Encounter Data Patuxent Box Turtle Study Encounter Data
The data set consists of eastern box turtle encounters made at Patuxent Refuge from 2019-2025 as part of organized field surveys on Central Tract.
Grass Carp diet and environmental data from the Lake Erie and Lake Michigan basins from 2019 to 2022 Grass Carp diet and environmental data from the Lake Erie and Lake Michigan basins from 2019 to 2022
Data include metabarcoding read data from grass carp associated with the Great Lakes removal program from 2019 to 2022. The anterior portion of the digestive tract was carefully separated from other organs for each captured grass carp and stored in 180 proof non-denatured ethanol. A 25 ml of subsampled gut contents was used for DNA purification and sequencing using polymerase chain...
Otter Creek pre-restoration orthomosaic and elevation products, Toledo, Ohio, September 2022 Otter Creek pre-restoration orthomosaic and elevation products, Toledo, Ohio, September 2022
The orthomosaic, digital surface model and point cloud presented here document conditions at Otter Creek in Toledo, Ohio in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights were approximately 400...

Nest number, description of nest structure and location, longitude, latitude, dates of observations, presence of adults, eggs, nestlings, outcome of reproductive effort, number of young fledged, body weight and culmen length of some nestlings, and osprey nest platforms occupied by Canada geese.
High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington, USA High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington, USA
This dataset consists of 3-component velocity time-series that describe ground shaking from simulated Mw7+ earthquakes on the southern Whidbey Island fault in Washington state. These were produced in support of the research project described in Stone et al. (2025) "High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington...
Shapefiles of Digitized Backwater Extent Behind Willwood Dam on the Shoshone River, near Cody, Wyoming Derived from 2012, 2015, 2017, 2019, and 2022 National Agriculture Imagery Program Imagery Shapefiles of Digitized Backwater Extent Behind Willwood Dam on the Shoshone River, near Cody, Wyoming Derived from 2012, 2015, 2017, 2019, and 2022 National Agriculture Imagery Program Imagery
The Wyoming-Montana Water Science Center, in cooperation with the Wyoming Department of Environmental Quality, digitized layers to determine the backwater extent behind Willwood Dam on the Shoshone River near Cody, Wyoming from 2012, 2015, 2017, 2019, and 2022 National Agriculture Imagery Program (NAIP) imagery. Digitizing layers of water extents behind Willwood Dam through time allows...
Modeled bedload-transport capacity for the Siletz River, Oregon Modeled bedload-transport capacity for the Siletz River, Oregon
Bedload-transport capacity models of the Siletz River, Oregon, were developed using standard sediment transport equations (Parker, 1990a,b; Wilcock and Crowe, 2003; Recking, 2013) for the reach from Moonshine Park to the town of Siletz, Oregon (river kilometers 87.2 to 68.5) to evaluate bedload transport capacity over a broad range of streamflows. Models were used to assess longitudinal...
Model outputs and model code for machine learning models forecasting streamflow drought across the Conterminous United States Model outputs and model code for machine learning models forecasting streamflow drought across the Conterminous United States
We applied machine learning (ML) models to forecast streamflow drought from 1 to 13 weeks into the future at more than 3,000 streamgage locations across the Conterminous United States. We applied two machine learning methods (long short-term memory [LSTM] neural network; light gradient boosting [LightGBM] machine) and two benchmark model approaches (persistence; autoregressive integrated...
At-site flood frequency estimates for 154 urban streamgages in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia using data through water year 2022 At-site flood frequency estimates for 154 urban streamgages in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia using data through water year 2022
This dataset contains site information and results of flood frequency analysis for 154 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia. Site information and annual peak-flow data from the 1924 - 2022 water years were obtained from the USGS National Water

Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq
This data release presents multi-proxy geochemical and sedimentological data from 20 short sediment cores (ranging 50–70 cm in depth) collected in 2003 along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the Lower Mesopotamian Plain, Iraq. The dataset includes X-ray fluorescence (XRF) elemental abundances, particle size distributions, visible and near-infrared spectrophotometry...
National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to the 2010s for the coast of Long Island Sound, New York and Connecticut National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to the 2010s for the coast of Long Island Sound, New York and Connecticut
The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from various historical sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. Shorelines are compiled in a GIS and analyzed in the USGS Digital Shoreline Analysis System (DSAS) software to calculate rates of...
