Water quality and seepage estimates collected at Lake Spokane, WA, 2016-2019 Water quality and seepage estimates collected at Lake Spokane, WA, 2016-2019
Shallow nearshore groundwater chemistry and estimates of groundwater seepage were collected across 21 locations along Lake Spokane, WA, beginning in October 2016 and ending in October 2019. Groundwater chemistry was collected using temporary mini-piezometers and seepage rates from Lee-type seepage meters. Sample locations are divided into two distinct types: Core sites, where seepage...
Ploidy and genome size estimates of artificially produced larval pallid sturgeon, Scaphirhynchus albus Ploidy and genome size estimates of artificially produced larval pallid sturgeon, Scaphirhynchus albus
Data consist of flow cytometry files (.FCS) that were generated in the analysis of larval pallid sturgeon specimens. Nuclei from produced larval sturgeon somatic cells were analyzed using flow cytometry to estimate genome size and assign ploidy. Freshly collected rainbow trout (Oncorhynchus mykiss), largemouth bass (Micropterus salmoides), or pallid sturgeon blood were used as external...
Geochemical Data for Illinois Basin Coal Samples, 2015-2018 (ver. 1.1, March 2021) Geochemical Data for Illinois Basin Coal Samples, 2015-2018 (ver. 1.1, March 2021)
Researchers at the U.S. Geological Survey (USGS) and their collaborators conducted a study of the geochemical properties of coals currently produced for electric power generation in the Illinois Basin in Illinois and Indiana. The study follows from recommendations by an expert panel for the USGS to investigate the distribution and controls of trace constituents such as mercury (Hg) in...
Microsatellite genotypes and DNA yield of artificially produced larval pallid sturgeon, Scaphirhynchus albus Microsatellite genotypes and DNA yield of artificially produced larval pallid sturgeon, Scaphirhynchus albus
Data consist of genotypes for pallid sturgeon and paddlefish broodstock and artificially-produced larvae at 19 sturgeon microsatellite loci and four paddlefish loci. Microsatellite genotypes allowed confirmation of homozygous sturgeon DNA and absence of paddlefish DNA in haploid gynogens. Data also consist of DNA yield estimates for haploid gynogens for proof of concept that haploid...
Reanalysis of Additional Selected Archived NURE-HSSR Sediment Samples from Idaho and Montana Reanalysis of Additional Selected Archived NURE-HSSR Sediment Samples from Idaho and Montana
In December of 2018, the U.S. Geological Survey (USGS) signed a Technical Assistance Agreement with a third party to reanalyze 2,324 archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Idaho and Montana. A small amount (approximately 0.25 grams [g]) of sieved...
Peak-flow frequency analysis for three selected streamgages in the Cedar and Little Sioux River Basins, Iowa, based on data through water year 2019 Peak-flow frequency analysis for three selected streamgages in the Cedar and Little Sioux River Basins, Iowa, based on data through water year 2019
This data release presents a peak-flow frequency analysis by the U.S. Geological Survey that was based on methods described by Eash and others (2013) for streamgages 05458300 Cedar River at Waverly, Iowa; 05458500 Cedar River at Janesville, Iowa; and 06606600 Little Sioux River at Correctionville, Iowa. These methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-...
