Data

Based on hydrologic data through the 2022 water year (October 1 to September 30), the U.S. Geological Survey South Atlantic Water Science Center updated low-flow frequency, mean annual flow, and flow-duration statistics at 843 streamgages in and near Georgia, North Carolina, and South Carolina. Data from 604 of those streamgages, on streams not substantially affected by regulation or...

These data were compiled for the National Park Service. Objective(s) of our study were to resurvey previously established cross sections on the Green River in Browns Park, Colorado and Utah, to document changes in channel width, depth, and cross-sectional area. In addition, new cross sections were established in areas that lacked previously surveyed cross sections. These data represent...

Because urban landscapes are heterogeneous, the methods and spatial resolution used to depict the land surface greatly influence the representation of urban features. Land cover products such as tree canopy cover (TCC) are particularly sensitive to the methodology and resolution used in their creation. Differences in TCC mapping have implications on the outcomes of ecosystem service (ES)...

A benchmark global water balance evapotranspiration (WBET) dataset was generated using machine learning for large-area bias correction of remote sensing-based evapotranspiration (RSET). The dataset contains WBET (1991-2020 average) of over 15,000 Level 6 HydroBASINS worldwide. Additionally, a comparison of this dataset with three RSET and a machine learning-based global datasets is...

This data release and metadata contains radio telemetry signal data used to track and describe movement and activity of Brown Treesnakes (Boiga irregularis) and Micronesian Starlings (Aplonis opaca) on Andersen Air Force Base, Guam, 2021-2022. Using a node network radio telemetry tracking system, multiple nodes would make detections of animals and record signal strength that could be...

This dataset contains 4 separate data files: (1) "Hawaiian Islands, genetic metabarcoding of Hawaiian hoary bat guano samples, 2010-2021" - sampling details for guano collected from Hawaiian hoary bats (Lasiurus semotus) on the Island of Hawai‘i, O‘ahu, Maui, and Kaua‘i, which was used in a dietary metabarcoding study; (2) "Hawaiian Islands, Hawaiian hoary bat guano representative DNA...

The Louisiana State Legislature established the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to conserve, restore, create and enhance Louisiana's coastal wetlands. Restoration plans developed under CWPPRA require evaluating the effectiveness of each project in achieving long-term solutions to coastal wetlands loss. This data set includes mosaicked aerial photographs...

This dataset provides whole-rock geochemical data for selected igneous, metamorphic, and volcanic rock samples collected in the Lane Mountain area about 20 to 30 kilometers northeast of Barstow, California, between the years 2014 and 2021. Data are reported for 231 analyses from 226 samples. Samples include Paleozoic and Mesozoic plutonic and metamorphic rocks and Cenozoic volcanic rocks...

Per- and polyfluoroalkyl substances (PFAS) and co-occurring constituents were assessed in the Upper Colorado River Basin during three sampling campaigns conducted from 2022 to 2024. In May 2022, discrete water samples were collected at five sites along a longitudinal transect from the Fraser River near Tabernash, Colorado to the Colorado River near Grand Junction, Colorado. Time series...

The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand and an understanding of the natural and human factors affecting the balance between supply and demand. A key part of...

This dataset was collected during the summer of 2024 within the Raystown Lake Project area (United States Army Corps of Engineers), within south-central Pennsylvania. Acoustic recording units were deployed across the project area to gather data on bat acoustic activity of all species that could potentially be present. This dataset contains identification data, summary identification data...

This data release contains all collected data sampled during vertical stratification events, as well as during times of vertical mixing within and around Suisun Cutoff, in Suisun Bay, CA. Data were collected using a holistic approach spatially and temporally, looking at hydrodynamics, biotic compositions, and water biogeochemistry throughout the water columns at designated points in...
