Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype Development and optimization of species-specific qPCR assays for eDNA detection of the mucket (Ortamannia ligamentina) and spectaclecase (Cumberlandia monodonta) mussels’ male mitotype
This dataset describes the sensitivity (limit of detection and limit of quantification) and specificity (list of species tested against the assays) of two qPCR assays designed to detect the male mitotype of two freshwater mussel species Ortmanniana ligamentina and Cumberlandia monodonta from water samples (eDNA).
Data associated with characterizing the exposure of the U.S. road network to areas susceptible to landslides, 2023 Data associated with characterizing the exposure of the U.S. road network to areas susceptible to landslides, 2023
Data supporting the journal article titled “Variations in road exposure and traffic volumes in the United States in areas susceptible to landslides.” There have been many efforts in the United States (U.S.) to identify landslide threats for specific roads, but no efforts to examine the entire national road system. We use geospatial tools to estimate the length and percentage of total...
Daily reference and potential evapotranspiration, supporting meteorological data from the Weather Research and Forecasting (WRF) model, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Southeastern United S Daily reference and potential evapotranspiration, supporting meteorological data from the Weather Research and Forecasting (WRF) model, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Southeastern United S
Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated at an approximately 1-kilometer spatial grid and daily time-step from January 1, 2024 to December 31, 2024 for Florida, Alabama, Georgia, South Carolina, and parts of Mississippi, North Carolina, and Tennessee. PET and ETo were computed from solar radiation, meteorological data (min/max temperature...
Daily reference and potential evapotranspiration, supporting meteorological data from weather stations, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Florida, 2024 Daily reference and potential evapotranspiration, supporting meteorological data from weather stations, solar insolation data from the GOES satellite, and blue-sky albedo data from the MODIS satellite, Florida, 2024
Potential evapotranspiration (PET) and reference evapotranspiration (ETo) are estimated at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-step from January 1, 2024 to December 31, 2024 for the entire State of Florida. PET and ETo were computed from solar radiation, meteorological data (min/max temperature, min...
Stable oxygen, hydrogen, sulfur, carbon, and nitrogen isotope analyses of mineral deposits and mineral occurrences Stable oxygen, hydrogen, sulfur, carbon, and nitrogen isotope analyses of mineral deposits and mineral occurrences
Stable isotope analyses are reported (the ratios deuterium/protium, carbon-13/carbon-12, oxygen-18/oxygen-16, sulfur-34/sulfur-32, nitrogen-15/nitrogen-14) for ores and related rocks, and mineral occurrences in sedimentary, igneous, and metamorphic rocks from Hicks Dome, Illinois; Clementine copper porphyry prospect, Boulder copper porphyry, and the Elkhorn Mining District, Montana; Pogo...
Measurement of Per- and Polyfluoroalkyl Substances in Graminaceous plants using three extraction techniques Measurement of Per- and Polyfluoroalkyl Substances in Graminaceous plants using three extraction techniques
Dataset contains measured concentrations of PFAS analytes and limits of detection/quantification for 37 total samples. There are 82 total PFAS analytes (7 non-extracted internal standards, 24 extracted internal standards, and 51 target native analytes) and each individual sample has been quantified for all 82 of these compounds. Samples are extracts of plant tissues from three sources...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of Yemen. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is...
Range-wide probability of persistence of Ornate Chorus Frog populations and a habitat suitability map Range-wide probability of persistence of Ornate Chorus Frog populations and a habitat suitability map
Data include the probability of persistence of 407 Ornate Chorus Frog (Pseudacris ornata) populations across the distribution, as well as the mean habitat suitability, mean winter precipitation, and proportion of the surface that is impervious within each buffered population. Data also include the probability of persistence of Ornate Chorus Frog populations when different buffer sizes...
Direct Human-Impact Classifications for Selected Groundwater Wells in the Conterminous United States, model archive Direct Human-Impact Classifications for Selected Groundwater Wells in the Conterminous United States, model archive
This data release contains data used to develop and apply a model that estimates the level of direct human-impact on selected groundwater wells in the conterminous United States. An extreme gradient boosting model was developed to estimate the probability of minimal human-impact to water levels in groundwater wells. The model uses human-impact evaluations from regional groundwater...
Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater
In the United States, the widespread use of pesticides has led to contamination of groundwater resources. Three decades ago, the U.S. Geological Survey (USGS) established a national water quality monitoring network for groundwater (NWQN-GW). This network provides an overview of groundwater conditions across a wide range of hydrogeologic settings and capture the impacts of pesticide use...
