Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanobacteria cultures from Lake Elsinore and Canyon Lake (CA, USA, 2016) for cyanotoxins and algal toxins

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 quadrupole mass sp

Liquid Chromatography Triple Quadrupole Mass Spectrometry (LC/MS/MS) analysis of cyanotoxins and algal toxins in estuary samples collected from California, USA, in 2016-17

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 collected

Bayou Sauvage NWR (LA) Haul Trail Snake Mortality, 2015-2017

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).

Time-lapse color photography of Milford Lake, Kansas, June through November 2017 and June through November 2018

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 Lake, Kansas,

Phytoplankton data for Milford Lake, Kansas, June through October 2018

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 research effor

Vertical profiles of water-quality data from two sites in Milford Lake, Kansas, August 24-25, 2017

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 fluorescence, and

Discrete water-quality data for the Kansas River and tributaries, July 2012 - September 2016

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, alkalinity
