Cyanobacterial Toxin Concentrations from Solid Phase Adsorption Toxin Tracking (SPATT) Samplers, Water, and Field Water-Quality Data from Monitoring Sites on the Clinch River from 2020-2023 Cyanobacterial Toxin Concentrations from Solid Phase Adsorption Toxin Tracking (SPATT) Samplers, Water, and Field Water-Quality Data from Monitoring Sites on the Clinch River from 2020-2023
In cooperation with the Tennessee Wildlife Resources Agency (TWRA) and University of Tennessee Knoxville (UTK), the U.S. Geological survey (USGS) collected cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and water-quality field data at 4 sites on the Clinch River from November 2020 to December 2023. The goal for the sample data was to...
Cyanobacterial Toxin Concentrations from Solid Phase Adsorption Toxin Tracking (SPATT) Samplers, Water, and Field Water-Quality Data from North-central Tennessee Reservoirs and Two Wells from 2022-2024 Cyanobacterial Toxin Concentrations from Solid Phase Adsorption Toxin Tracking (SPATT) Samplers, Water, and Field Water-Quality Data from North-central Tennessee Reservoirs and Two Wells from 2022-2024
In cooperation with the Tennessee Department of Environment and Conservation (TDEC), the U.S. Geological Survey (USGS) measured cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and collected water-quality field data at 18 sites in North-central Tennessee from August 2022 to November 2024. Additionally, selected sites also were sampled...
Current and future hydrology and occupancy predictions for boreal toads (Anaxyrus boreas boreas) in the Southern Rocky Mountains Current and future hydrology and occupancy predictions for boreal toads (Anaxyrus boreas boreas) in the Southern Rocky Mountains
These data consist of three primary types of products for managers of boreal toads in the Southern Rocky Mountains: 1) Re-constructed hydroperiods for historical breeding sites from LANDSAT imagery from 1985-2022 (SMA_hydroperiod_reconstruction.csv). This dataset was developed using a Spectral Mixture Analysis (SMA). 2) Current (1985-2022) and future (2040-2069) predictions of...
Chesapeake Bay Hyper-Resolution Hydrography Database Chesapeake Bay Hyper-Resolution Hydrography Database
The Chesapeake Bay Hyper-Resolution Hydrography Database is intended to facilitate analysis of the landscape in the Chesapeake Bay watershed through identification of headwater and other low-order streams or drainage features (e.g. ditches) that, to date, may be absent from existing hydrography data products. A full description of the methodology and accuracy assessment is provided in...
Fine Scale Historical Climate and Hydrology for Sentinel Monitoring Locations in California using the Basin Characterization Model (BCM) Fine Scale Historical Climate and Hydrology for Sentinel Monitoring Locations in California using the Basin Characterization Model (BCM)
This data release includes downscaled climate inputs and hydrologic outputs from 41 Basin Characterization Models (BCM) version 8 (v8), described in Flint and others (2021), with a 10 by 10-meter spatial resolution at monthly intervals from water years 1896 to 2023. Forty-one (41) models were developed for sentinel monitoring locations in Wildlife Areas and Ecological Reserves in...
Monotonic trend computations for streamflow statistics within and near the Mobile Bay and Perdido Bay watersheds, United States, 1950–2022 Monotonic trend computations for streamflow statistics within and near the Mobile Bay and Perdido Bay watersheds, United States, 1950–2022
This data release provides comprehensive results of monotonic trend assessment for long-term U.S. Geological Survey (USGS) streamgages in or proximal to the watersheds of Mobile and Perdido Bays, south-central United States (Tatum and others, 2024). Long-term is defined as streamgages having at least five complete decades of daily streamflow data since January 1, 1950, exclusive to those
