Bathymetry and Water-Quality Data of Surface Water Bodies in Cook County, Illinois, 2022 (ver. 2.0, January 2025) Bathymetry and Water-Quality Data of Surface Water Bodies in Cook County, Illinois, 2022 (ver. 2.0, January 2025)
The U.S. Geological Survey (USGS), in cooperation with the Cook County Bureau of Technology (BOT), prioritized waterbodies (lakes, rivers, and canals) of interest within Cook County to survey in 2022. These surveys describe the bathymetry and basic water-quality conditions observed, and could be used by the BOT to assist with resource management decisions and uses, as well as build an...
Data from the Inventory of Montane-nesting Birds in the Aniakchak National Monument and Preserve, Alaska Data from the Inventory of Montane-nesting Birds in the Aniakchak National Monument and Preserve, Alaska
This data package contains six tables: 1) characteristics of bird survey sites, 2) vegetation classification at survey sites, 3) detections of all birds at survey sites, 4) behaviors of all birds at survey sites, 5) bird taxonomy and indication of conservation status, and 6) habitat information pertaining to survey site photographs. The objectives of the survey were to 1) use targeted...
Data for karst groundwater vulnerability determined by modeled age and residence time tracers Data for karst groundwater vulnerability determined by modeled age and residence time tracers
Groundwater samples collected from the Edwards aquifer in south-central Texas were analyzed for water-quality data to assess aquifer susceptibility to contaminants. Water-quality data included environmental tracers of groundwater age (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14, and radiogenic helium-4), calibrated to lumped parameter models (LPMs). Groundwater samples...
Environmental DNA of selected terrestrial vertebrates and bacteria detected in the Platte River near Ashland, Nebraska 2019-22 Environmental DNA of selected terrestrial vertebrates and bacteria detected in the Platte River near Ashland, Nebraska 2019-22
Water samples from the Platte River were collected and analyzed for environmental DNA (eDNA). The U.S. Geological Survey (USGS) Nebraska Water Science Center (NEWSC) collected samples monthly from November 2019 to September 2022 at the Platte River near Ashland, Nebraska (USGS: 06801000). The USGS, in cooperation with the City of Lincoln, collected these samples. Water from the Platte...
SUPERSEDED: Pacific Walrus Coastal Haulout Occurrences Interpreted from Satellite Imagery, 2023 SUPERSEDED: Pacific Walrus Coastal Haulout Occurrences Interpreted from Satellite Imagery, 2023
This data release contains maps, geospatial files, and a table of the satellite imagery types with the dates when they were collected and examined to interpret the presence of, and area occupied by, walruses at terrestrial haulouts. Estimates of the land area occupied by walruses are provided based on interpretation by experienced image reviewers. The images are from a variety of Earth...
whitetailedSIRS: A package to project SARS-CoV-2 outbreak dynamics in white-tailed deer whitetailedSIRS: A package to project SARS-CoV-2 outbreak dynamics in white-tailed deer
This software release contains several R scripts that generate epidemic projections of SARS-CoV-2 in white tailed deer populations using a Susceptible-Infected-Recovered-Susceptible (SIRS) modeling framework. We provide a workflow of vignettes used in Rosenblatt et al. In Prep and Cook et al. In Prep. Users are able to specify transmission parameters for human-deer and deer-deer...
