Water-column environmental variables and accompanying discrete CTD measurements collected offshore the U.S. Mid- and South Atlantic Water-column environmental variables and accompanying discrete CTD measurements collected offshore the U.S. Mid- and South Atlantic
Various water column variables, including salinity, dissolved inorganic nutrients, dissolved inorganic carbon, and radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from deepwater sites offshore the US Mid- and South Atlantic from September 2017 to April 2019. CTD (Conductivity Temperature Depth) data were also collected at each...
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 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...
Avian Eggshell Thickness for 12 Species in the Western U.S. from 2014 to 2018 Avian Eggshell Thickness for 12 Species in the Western U.S. from 2014 to 2018
Eggshell thickness was measured at the egg equator and poles (sharp pole and blunt pole) for 12 avian species. Eggshell thickness was related to egg morphometrics (egg length and width), embryonic development, egg status, and mercury contamination. Individual eggshells each have up to 3 thickness measurements, linked by the eggshell identification. Each measurement has the corresponding...
Salvator merianae trapping in Georgia, USA Salvator merianae trapping in Georgia, USA
Argentine Giant Tegu lizard (Salvator merianae) trap effort and count data collected in southern Georgia, USA in 2019. Non-target species associated with the traps were also documented, as were type of bait used and condition of the traps during trap checks.
Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA
The dataset contains quantitative polymerase chain reaction data for microbial source tracking markers screened on water samples collected from streams and rivers within and bounding Congaree National Park from samples collected throughout the year from December 2017 through June 2019. The number of samples collected per event ranged from 4-16 over the span of 11 sample events.
Target-Chemical Concentration Results of Mixed-Organic/Inorganic Chemical Exposures in Cape Cod, Massachusetts Tapwater, 2018 Target-Chemical Concentration Results of Mixed-Organic/Inorganic Chemical Exposures in Cape Cod, Massachusetts Tapwater, 2018
This dataset provides the water-quality results for organic and inorganic concentrations analyzed from samples collected at residential tapwater faucets, sourced from private drinking water wells in Cape Cod, Massachusetts. Samples were collected in July and August, 2018 from 20 locations. Samples were analyzed at various U.S. Geological Survey laboratories: the National Water Quality...
