Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Methylmercury Effects on Birds: Bibliography and Dataset for the Development of Toxicity Reference Values for Injury Assessment Methylmercury Effects on Birds: Bibliography and Dataset for the Development of Toxicity Reference Values for Injury Assessment
This data release contains three files. The first (Table S1 Bibliography Dataset) contains the entire bibliography for the 435 publications examined for potential inclusion into at least one of the meta-analyses for the effects of environmental mercury (Hg) on birds. For those 168 publications that were included in at least one meta-analysis, the worksheet titled Bibliography contains...
Grass Carp Movement and Capture Data from the Sandusky River, Lake Erie, Ohio, USA from 2020 to 2022 Grass Carp Movement and Capture Data from the Sandusky River, Lake Erie, Ohio, USA from 2020 to 2022
Data includes grass carp position and sampling data from 2020 to 2022. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from...
Abandoned Mine Land (AML) Geochemical Data: Spor Mountain, Utah Abandoned Mine Land (AML) Geochemical Data: Spor Mountain, Utah
The Spor Mountain study area is located in the Spor Mountain Range, approximately 42 miles northwest of Delta, Utah. Mining in the Spor Mountain district began in the 1940s and continues to present day. Fluorspar, uranium, and beryllium are the main ores mined(Ege, 2005). From August through September 2013, the United States Geological Survey (USGS) collected a total of 73 samples from...
Cyanobacteria, cyanotoxins and associated characteristics across the North Atlantic Appalachian Region Cyanobacteria, cyanotoxins and associated characteristics across the North Atlantic Appalachian Region
This data release contains cyanotoxin, chlorophyll-a, and pheophytin-a concentration, cyanobacterial genetics, phytoplankton community composition, and multiparameter sonde data collected from 20 sites in five northeastern United States river basins (Penobscot (ME), Santuit (MA), York (VA-WV), Salem (NJ), and Peconic (NY)). Solid Phase Adsorption Toxin Tracking (SPATT) passive samplers...
Data for Infectivity of Wild-Bird Origin Influenza A Viruses in Minnesota Wetlands Across Seasons Data for Infectivity of Wild-Bird Origin Influenza A Viruses in Minnesota Wetlands Across Seasons
This data set represents an ecological and laboratory-based experiment to understand influenza virus viability in surface water. Data tables included in this release consist of 1) daily mean water temperature, 2) viability of viruses maintained in water, 3) influenza detection in duck samples, 4) viral titers of experimentally inoculated water samples, and 5) water chemistry.
Hydrodynamic and Water-Temperature Model of a 21-Mile Reach of the Upper Illinois River, Illinois, 2020 – 2022 (ver. 1.1, October 2024) Hydrodynamic and Water-Temperature Model of a 21-Mile Reach of the Upper Illinois River, Illinois, 2020 – 2022 (ver. 1.1, October 2024)
A hydrodynamic and water-quality model (CE-QUAL-W2) was developed of a 21-mile reach of the upper Illinois River including a 3-mile reach of a major tributary, the Fox River. The CE-QUAL-W2 model is 2-dimensional in the vertical and longitudinal directions and averaged over the lateral direction. Continuous water quality and streamgage data provided time-series data for model boundary...
