Data

Cyanobacteria are common in inland water bodies. Many strains are known to produce potent toxins (cyanotoxins) which can impact human and animal health in sufficient concentrations. Lake Elsinore and Canyon Lake are two impaired lakes in California with frequent cyanobacteria blooms that are not monitored for toxin production. These data document the liquid chromatography triple...

Cyanobacteria are primary producers present in many water bodies, certain types of which may produce potent toxins (known as cyanotoxins). They are known to impact human and animal health when exposed through recreational activities, consumption, and inhalation. In an effort to understand the presence of toxin-producing cyanobacteria in California water bodies, cyanobacteria samples were...

Comprehensive list of carcasses detected at Haul Trail in Bayou Sauvage National Wildlife Refuge (Orleans Parish, LA) and relevant findings for specimens subject to postmortem examination at the USGS National Wildlife Health Center (Madison, WI).

This U.S. Geological Survey (USGS) Data Release provides time-lapse color photography collected from three sites at Milford Lake, Kansas, during June through November 2017 and June through November 2018. Photographic images are displayed using a .mp4 common multimedia format. Time-lapse cameras were used to visually capture cyanobacterial accumulations and movement throughout Milford...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Milford Lake, Kansas, during June through October 2018. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the federal open-data requirements as a way to make scientific products associated with USGS...

This U.S. Geological Survey (USGS) Data Release provides vertical profiles of water-quality data collected from two sites in Milford Lake, Kansas, August 24-25, 2017. Data are rounded to USGS significant figures. A multiparameter water-quality sonde was used to measure water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin...

This U.S. Geological Survey (USGS) Data Release provides discrete water-quality data collected from four sites on the Kansas River and four of its tributaries during July 2012 through September 2016. The water-quality constituents included in this data release are the cyanotoxins microcystin and cylindrospermopsin, the taste-and-odor compounds geosmin and 2-methylisoborneol, major ions...

This data release contains the inputs and outputs from the development of Escherichia coli (E. coli) concentration models for the four Missouri River sites near Omaha, Nebraska. Model development, models, and results are published in the associated U.S. Geological Survey (USGS) report Densmore and others, 2020. Load Estimator models (LOADEST) (Runkel and others, 2004) were developed from...

This data release includes stormwater inflow, outflow, and subsurface storage data for two bioretention gardens located in Omaha, Nebraska. Additionally, two additional datasets are included which contain meteorology and evapotranspiration data for each site. These sites were located at the Douglas County Health Center (DCHC), and the Eastern Nebraska Office on Aging (ENOA).

This U.S. Geological Survey (USGS) Data Release provides the phytoplankton tally sheet, including photomicrographs, for samples collected from eleven large river sites throughout the United States, from June through September 2017. All data are raw tallies, not calculated abundances or concentrations. The dataset includes all routine and quality assurance/quality control samples...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data for samples collected from eleven large river sites throughout the United States, from June through September 2017. All data are reported as raw calculated values and are not rounded to USGS significant figures. The dataset includes all routine and quality assurance/quality control samples collected as part of a...

This U.S. Geological Survey (USGS) data release provides discretely measured cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected from eleven large river sites throughout the United States, from June through September 2017. Discrete water-quality samples were analyzed for cyanotoxins (anatoxin, cylindrospermopsin, microcystin, and saxitoxin), chlorophyll...
