Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2024 Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2024
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings...
Data supporting the validation of First Annulus of Grass Carp Ctenopharyngodon idella and Silver Carp Hypophthalmichthys molitrix Data supporting the validation of First Annulus of Grass Carp Ctenopharyngodon idella and Silver Carp Hypophthalmichthys molitrix
A total of 83 Grass Carp and 92 Silver Carp were collected monthly from stocked ponds at Columbia Environmental Research Center. Length, weight, and collection date were recorded. The dorsal-fin rays and lapilli otoliths were collected from these specimens for the purpose of aging. An additional set of dorsal-fin rays and lapilli otoliths from Grass Carp collected in Truman Reservoir...
Geochemical data, thin section images, and modal mineralogy of selected bedrock samples in the western half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina Geochemical data, thin section images, and modal mineralogy of selected bedrock samples in the western half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina
This data release contains geochemical data, thin section images, and modal mineralogy from bedrock samples collected in the western half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina. The geochemical data comprise whole-rock major oxide and trace element abundances in 246 samples. Pairs of thin section images in plane-polarized light and cross-polarized light are...
Campylorhynchus brunneicapillus Single Nucleotide Polymorphism Genotype Data from Southern California, USA Campylorhynchus brunneicapillus Single Nucleotide Polymorphism Genotype Data from Southern California, USA
This dataset contains 184 single nucleotide polymorphism (SNP) genotypes of Campylorhynchus brunneicapillus (Cactus Wren) sampled in southern California. Genomic markers were generated from ddRAD loci and analyzed using the Stacks v2.60 pipeline. The genotypes for all samples are provided in a VCF file with 40,707 independent loci. A companion sample data file is provided with sample...
Harbison's Dun Skipper (Euphyes vestris harbisoni) Single Nucleotide Polymorphism Genotype Data from Southern California Harbison's Dun Skipper (Euphyes vestris harbisoni) Single Nucleotide Polymorphism Genotype Data from Southern California
This dataset contains genotypes from 148 Harbison's dun skipper (Euphyes vestris harbisoni) collected in San Diego and Orange County, California (USA). Genomic markers were generated using the 2RAD restriction-associated DNA sequencing protocol, aligned to a reference genome of Euphyes dion (genome assembly GCA_018251475.1) and analyzed using Stacks v2.53. The genotypes for all samples...
Ecological Potential Fractional Component Cover Based on Long-Term Satellite Observations Across the Western United States Version 2 Ecological Potential Fractional Component Cover Based on Long-Term Satellite Observations Across the Western United States Version 2
Rangelands have immense inherent spatial and temporal variability, yet assessments of land condition and trends are often assessed relative to the condition of a limited number of representative points or in some cases reference data is lacking. Ecological Potential (EP) data are spatially comprehensive and quantitative baseline for comparison of current rangeland vegetation conditions...
