Urban Waters Federal Partnership: Novel bacteria monitoring technology in support of recreational water quality monitoring in the Lower Delaware River Urban Waters Federal Partnership: Novel bacteria monitoring technology in support of recreational water quality monitoring in the Lower Delaware River
The United States Geological Survey’s (USGS) New Jersey Water Science Center, in coordination with the Delaware River Basin Commission (DRBC) deployed a novel bacterial water-quality monitor, the Fluidion Alert V2 (Fluidion), in the Delaware River at Pyne Poynt Park in Camden County, New Jersey. Following United States Environmental Protection Agency (EPA) recreational water quality...
HOPS: Hyperparameter optimization and predictor selection HOPS: Hyperparameter optimization and predictor selection
We developed the hyperparameter optimization and predictor selection (HOPS) software to optimize hyperparameters and predictor selection while limiting correlation among the selected predictors for machine learning models. Including correlated predictors in machine learning models can distort model estimation and prediction and introduce bias in predictor importance estimates. The HOPS...
Peak-Flow Frequency Analysis for 464 U.S. Geological Survey Streamgages in Illinois, Indiana, and Wisconsin, Based on Data Through Water Year 2017 Peak-Flow Frequency Analysis for 464 U.S. Geological Survey Streamgages in Illinois, Indiana, and Wisconsin, Based on Data Through Water Year 2017
The U.S. Geological Survey (USGS) Central Midwest Water Science Center (CMWSC) completed a report (Over and others, 2023) documenting methods for peak-flow frequency analysis in Illinois following Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for...
Channel incision characteristics in Clarksburg, MD Channel incision characteristics in Clarksburg, MD
This dataset describes field-measured qualitative stream channel characteristics indicative of incision and remotely-measured predictions of channel incision from lidar in three headwater streams in the Piedmont physiographic region of Maryland. The files within the field-measured channel incision folder include 1) a point file of original survey locations with a description of channel
Gene Transcription and Heat Shock Protein 70 Abundance in Juvenile Hatchery Reared Coho Salmon and Chinook Salmon during a Manipulative Thermal Experiment, Anchorage, Alaska 2020-2021 Gene Transcription and Heat Shock Protein 70 Abundance in Juvenile Hatchery Reared Coho Salmon and Chinook Salmon during a Manipulative Thermal Experiment, Anchorage, Alaska 2020-2021
This dataset consists of two tables with the results from two manipulative thermal experiments with juvenile coho salmon (May 2021) and juvenile Chinook salmon (May 2020) and include 1) gene transcription results and heat shock protein 70 abundance in coho salmon and Chinook salmon and 2) water temperatures to which fish were exposed during the experiment.
Reduced representation sequencing and genotyping of Arizona Toads (Anaxyrus microscaphus) from the southwestern United States Reduced representation sequencing and genotyping of Arizona Toads (Anaxyrus microscaphus) from the southwestern United States
The dataset consists of genotypes (diploid base calls at variant sites) at 3,601 anonymous sites of the Arizona Toad (Anaxyrus microscaphus) nuclear genome. The genotyped samples are representative of the range of the species and its major population units, and the genotyped loci have a high degree of completeness. This data release consists of several files: 1. sample.metadata.txt...
