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
Survey Responses Collected in 2024 Measuring End-users' and Experts' Experiences Being Engaged in Development of Scientific Tools Survey Responses Collected in 2024 Measuring End-users' and Experts' Experiences Being Engaged in Development of Scientific Tools
Engagement of end-users and fellow experts is fundamental to the creation of useful scientific tools. We conducted a survey-based research project to assist scientists responsible for creating scientific tools by evaluating their engagement of end-users and experts in the development of these tools. Our study includes a suite of six United States Geological Survey (USGS) projects that...
Values Mapping for Planning in Regional Ecosystems: Mojave Trails National Monument, California, 2024 Values Mapping for Planning in Regional Ecosystems: Mojave Trails National Monument, California, 2024
Values Mapping for Planning in Regional Ecosystems (VaMPIRE) is a Public Participatory GIS tool developed by the U.S. Geological Survey in collaboration with the Bureau of Land Management to aid in gathering information from the public about their values for public lands and waters. This contains data from 121 surveys returned in 2024 for the Mojave Trails National Monument in California...
Geochemical, mineralogical, and grain-size data for deep cores from the Cache Creek Settling Basin and streambed sediments from the Sacramento River watershed Geochemical, mineralogical, and grain-size data for deep cores from the Cache Creek Settling Basin and streambed sediments from the Sacramento River watershed
The Cache Creek Settling Basin (CCSB) is a 13.3 km2 levee-bounded sediment retention basin located at the modern terminus of Cache Creek near the eastern boundary of Yolo County, approximately two miles NE of Woodland, California. The Cache Creek Settling Basin was constructed in 1937 by the U.S. Army Corps of Engineers to trap suspended sediment from the upper Cache Creek watershed...
Data and model for mapping groundwater total dissolved solids at the San Ardo Oil Field, Monterey County, California, USA Data and model for mapping groundwater total dissolved solids at the San Ardo Oil Field, Monterey County, California, USA
The U.S. Geological Survey (USGS) compiled and analyzed data for mapping groundwater total dissolved solids (TDS) at the San Ardo Oil Field in Monterey County, California. Data include groundwater TDS and bicarbonate concentration from oil well and groundwater well samples, formation resistivity from borehole geophysical logs, porosity from well logs and rock core samples, temperature...
Lifespan of marsh units in E.B. Forsythe NWR and Atlantic-facing New Jersey salt marshes Lifespan of marsh units in E.B. Forsythe NWR and Atlantic-facing New Jersey salt marshes
This data release contains the estimated lifespans of salt marshes in E.B. Forsythe National Wildlife Refuge (EBFNWR) and Atlantic-facing New Jersey. The lifespans are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2024) and Defne and Ganju...
Bat acoustic monitoring in Western Washington's National Parks Bat acoustic monitoring in Western Washington's National Parks
US Geological Survey and National Park Service researchers designed and implemented an acoustic monitoring program for bats in the three large parks of Western Washington, all part of the North Coast and Cascades Network (NCCN) of National Parks.This work was part of the larger NCCN bat population monitoring and white-nose syndrome (WNS) surveillance program, designed to understand bat
