Harmful algal blooms (HABs) are characterized by excessive growth of algae. In freshwater environments, algal blooms, including those caused by cyanobacteria, can produce toxins that may impact human health, wildlife, and the environment. HABs are a growing public health concern but they remain difficult to predict due to the complex conditions driving their formation. This data release...

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...

Note: this data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P14HJGZI The data in this Data Release are used to calibrate a Geographic Information System (GIS) based hydraulic modeling tool developed by the U.S. Geological Survey (USGS) for Massachusetts in cooperation with the Massachusetts Department of Environmental Protection (MassDEP). USGS...

Beginning at about 2:15 am on May 27, 2016, a landslide from the headscarp of the May 25, 2014, West Salt Creek rock-avalanche deposit (White and others, 2015; Coe and others, 2016; Lewis and others, 2023; Coe and others, 2026) moved into a sag pond at the head of the deposit. At about 2:30 am, the landslide caused the sag pond, which already had an elevated water level due to runoff...

Surface water storage, including wetlands and lakes, is not typically considered in hydrological model calibrations. We tested a multivariate calibration process (Latin Hypercube Sampling), incorporating Sentinel-1/2 surface water storage, for a Soil and Water Assessment Tool model across the 0.5 million km^2 Upper Mississippi River Basin. While 19% of the 2000 parameter sets adequately...
