Validation and Application of a Standardized Quantitative PCR Assay for the Assessment of Antimicrobial Resistance Genes Validation and Application of a Standardized Quantitative PCR Assay for the Assessment of Antimicrobial Resistance Genes
This data set describes results for two laboratory experiments to validate a quantitative PCR assay for the assessment of antimicrobial resistance genes in surface waters. Data are also provided for the application of the assay surface water samples collected from three national parks in Alaska.
Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city. Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city.
Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land use segregation vary over years, these maps provide an important spatial lens in determining how patterns of segregation spatially and temporally developed during the course of the past century. Using a high-resolution land...
Unknown fish fin clip DNA analysis, April 2025 Unknown fish fin clip DNA analysis, April 2025
We tested 28 fin clips for DNA of Goldfish (Carassius auratus) and Prussian Carp (Carassius gibelio) following published assay methods. Results are reported as cycle threshold (Cq) values generated using real-time PCR.

This data release supports the publication in the Soil and Tillage Research journal titled "Multiyear Crop Residue Cover Mapping Using Narrow-Band vs. Broad-Band Shortwave Infrared Satellite Imagery" by Lamb and others (2025) (https://doi.org/10.1016/j.still.2025.106524) The dataset includes field sampling data comprising in-field nadir photographs collected from a collaborating farm in...
Data for the Potomac River Watershed Accumulated Wastewater Viewer Data for the Potomac River Watershed Accumulated Wastewater Viewer
This data release contains measured streamflow data from U.S. Geological Survey (USGS) streamgages and reported wastewater data from wastewater treatment plants (WWTP) discharge monitoring reports (DMRs) within the Potomac River watershed between October 1, 2021 and September 30, 2024. Mean monthly streamflow data was obtained from 117 USGS streamgages (Table1_Streamgages.csv). Average...
Seamless high-resolution transboundary dynamic landcover map of the Sonoran and Mojave Desert ecoregion within Bird Conservation Region 33 Seamless high-resolution transboundary dynamic landcover map of the Sonoran and Mojave Desert ecoregion within Bird Conservation Region 33
These data were compiled for the creation of a continuous, high-resolution transboundary land cover map of the Sonoran and Mojave Desert ecoregion within Bird Conservation Region 33 (BCR 33). Objective(s) of our study were to, 1) develop a machine learning algorithm trained to classify vegetation land cover using remote sensing spectral data and phenology metrics from 2013-2021, over the...
