Atmospheric mercury (Hg) deposition, which has been declining in North America since 1985, is the preeminent delivery pathway to the Great Lakes, making them sentinels for tracking shifts in atmospheric deposition. Lake productivity is changing as a result of reductions in phosphorus inputs and habitat shifts in productivity due to invasive mussels. This has altered Hg cycling and...

This data release contains supporting materials for a study testing the applicability of an image-derived water-level method at three U.S. Geological Survey (USGS) streamgage sites around Lake Redstone in Wisconsin (site numbers 05404140, 05404150, and 05404147) during Water Year 2020 (Johnson, et al., 2025). Two types of reference objects were tested in this study: white polyvinyl...

Phytoplankton samples were collected from Lake Pepin (a natural, riverine lake on the Upper Mississippi River) from 2012-2014. The dataset includes phytoplankton community data (i.e., genus, species, biovolume, etc.), as well as zooplankton, rotifer, cladoceran and water quality data.

In order to understand the provenance of lead in the surface water, groundwater, soils, and shallow pore water within and near the Middleton Municipal Airport–Morey Field (C29) in Middleton, WI, a subset of samples were sent to the Wisconsin State Lab of Hygiene for analysis. The results of these analyses are included in this data release and include both low-level lead concentrations...

This data release collates stream water temperature observations from across the United States from four data sources: The U.S. Geological Survey's National Water Information System (NWIS), Water Quality Portal (WQP), Spatial Hydro-Ecological Decision Systems temperature database (EcoSHEDS), and the U.S. Fish and Wildlife's NorWeST stream temperature database. These data were compiled...

From May 3–10, 2022, bathymetric and water velocity data were collected on the St. Croix River between Riverside and St. Croix Falls, Wisconsin. Bathymetry and water velocity data were collected at 2 transects for 102 cross sections over the approximately 120-kilometer (km) survey reach. Longitudinal profile bathymetry transects were also collected between each cross section. These data...

Datasets used in developing a large volume concentration method to recover avian influenza. These tables include: (1) Information on the solutions used in tests 1 and 2, (2) field parameter at collection and air temperature data corresponding to periods of raw wetland transport and storage, (3) full results of the laboratory studies, (4) results of the ultrafilter test, and (5) standard...

As part of the larger Great Lakes Cooperative Science and Monitoring Initiative (CSMI) , the U.S. Geological Survey Mercury Research Laboratory (MRL) completed a binational assessment partnering with the U.S. Environmental Protection Agency (US EPA), Environmental Climate Change Canada (ECCC), Michigan-DNR (MI-DNR), University of Minnesota-Duluth Natural Resources Research Institute (UM...

An inventory of facilities that bottle water or other beverages containing water (including soft drinks, beer, wine, or spirits) or that manufacture ice was compiled by combining available datasets from multiple sources. This water bottling inventory dataset includes facilities within all 50 states of the United States (U.S.), one federal district (Washington, District of Columbia), and...

Pesticide formulations containing the active ingredient Antimycin-A (ANT-A) have been used by fisheries and aquaculture managers for several decades to remove nuisance fish species. Analytical methods for measuring ANT-A during pesticide treatments have been reported using High Performance Liquid Chromatography (HPLC) paired with multiple detection methods (e.g., electrochemical...

This dataset includes average, and annual average (e.g., average of 2020) watershed characteristics and environmental driver data for 189 rivers across the Northern Hemisphere. Average data includes lithology (e.g., percent of watershed covered by volcanics), land use (e.g., percent of watershed covered by cropland), maximum day length, median nitrogen and phosphorus concentrations...

This dataset includes monthly dissolved silicon (DSi) concentration data from 198 rivers across the Northern Hemisphere. Concentration and discharge data were sourced from public and/or published datasets and the Weighted Regressions on Time, Discharge, and Season model (Hirsch et al. 2010) was used to estimate monthly concentrations and flow-normalized concentrations for all sites over...
