Algal toxins and Mycobacterium avium ssp. paratuberculosis measured in surface-water, quarry-water, and sediment samples collected at Pipestone National Monument, Pipestone, Minnesota, 2018-19 Algal toxins and Mycobacterium avium ssp. paratuberculosis measured in surface-water, quarry-water, and sediment samples collected at Pipestone National Monument, Pipestone, Minnesota, 2018-19
The U.S. Geological Survey, in cooperation with the U.S. National Park Service, conducted a study to determine the presence of algal toxins and Mycobacterium avium ssp. paratuberculosis (MAP) within Pipestone National Monument located in Pipestone County in southwestern Minnesota. Three algal toxins (microcystins, saxitoxin, and anatoxin-a) were analyzed in 12 water-quality samples...
Limnological Data from Experimental Exposure of Juvenile Coho Salmon (Oncorhynchus kisutch) to Elodea in a High Latitude Lake Limnological Data from Experimental Exposure of Juvenile Coho Salmon (Oncorhynchus kisutch) to Elodea in a High Latitude Lake
This dataset provides nine tables of data from an experimental study in which juvenile Coho Salmon (Oncorhynchus kisutch) were reared in floating net pens (limnocorrals) and exposed to Elodea spp. (a potential invasive species in high latititude lakes) and native aquatic vegetation. Data include: (1) coho salmon body, otolith, and stable isotope measurements, (2) abundance of...
U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-Ablation Split Stream (LASS) Analysis of Igneous Zircons from the Western Alaska Range U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-Ablation Split Stream (LASS) Analysis of Igneous Zircons from the Western Alaska Range
This dataset contains U-Pb isotopic data and ages, Hf isotope data, and trace element concentrations of zircon from igneous rocks collected from the western Alaska Range of south-central Alaska. The sample suite was collected as part of geological mapping and supporting geochemical and geochronological analysis conducted from 2011 to 2013. We also analyzed portions of remainders of...

An R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method Weighted Regressions on Time, Discharge, and Season (WRTDS).
Flood-Inundation Maps of the Meramec River from Eureka to Arnold, Missouri, 2018 Flood-Inundation Maps of the Meramec River from Eureka to Arnold, Missouri, 2018
Digital flood-inundation maps for a 37.2-mile reach of the Meramec River from Eureka to Arnold, Missouri, were created by the U.S. Geological Survey (USGS) in cooperation with the U.S. Army Corps of Engineers, Metropolitan St. Louis Sewer District, Missouri Department of Transportation, Missouri American Water, Federal Emergency Management Agency Region 7, and the cities of Pacific...
Model Archive Summary for Suspended-Sediment Concentration at Station 11185185 – Lower Sensor; Suisun Bay at Mallard Island, California, Water Year 2018 - 2020 Model Archive Summary for Suspended-Sediment Concentration at Station 11185185 – Lower Sensor; Suisun Bay at Mallard Island, California, Water Year 2018 - 2020
This model archive summary details the suspended-sediment concentration (SSC) model developed to compute 15-minute SSC values from 15-minute turbidity data for the period October 01, 2017 through September 30, 2020. The methods used follow U.S. Geological Survey (USGS) guidance as referenced in Office of Water Quality Technical Memorandum 2016.10 (USGS 2016) and USGS Techniques and...
Sediment model inputs and outputs for the Smith Creek watershed near New Market, Virginia for 2012-2016 Sediment model inputs and outputs for the Smith Creek watershed near New Market, Virginia for 2012-2016
This data release includes data created, collected, and/or otherwise modified in the process of quantifying a sediment budget for the Smith Creek Watershed near New Market, Virginia, USA. Five raster files are included, namely a modeled index of hydrological connectivity, a raster model of modeled floodplain depositional masses and extent, a rasters of modeled gross and delivered upland...
Gavia Species Identification and Diet Composition from Feces, Central North Slope, Alaska, 2012-2014 Gavia Species Identification and Diet Composition from Feces, Central North Slope, Alaska, 2012-2014
This data set is comprised of one table with sampling information and NCBI BioProject accession numbers for sequence information of this amplicon-based study targeting Loon (Gavia sp.) and fish species expected in lake systems of the North Slope of Alaska from fecal samples. Highly conserved primers which could differentiate species of interest were developed for five portions of gavia...
Toxicological responses to sublethal anticoagulant rodenticide exposure in free-flying red-tailed hawks Toxicological responses to sublethal anticoagulant rodenticide exposure in free-flying red-tailed hawks
An important component of assessing the hazards of anticoagulant rodenticides to non-target wildlife are observations in exposed free-ranging individuals. The objective of this study was to determine if environmentally realistic, sublethal first-generation anticoagulant rodenticide exposures via prey, can result in direct or indirect adverse effects to free-flying raptors. We offered...
Biogeochemical and source characteristics of preferential groundwater discharge in the Farmington River watershed (Connecticut and Massachusetts, 2017 - 2021) Biogeochemical and source characteristics of preferential groundwater discharge in the Farmington River watershed (Connecticut and Massachusetts, 2017 - 2021)
We used spatial data from previously mapped preferential groundwater discharges throughout the Farmington River watershed in Connecticut and Massachusetts (https://doi.org/10.5066/P915E8JY) to guide water sample collection at known locations of groundwater discharging to surface water. In 2017 and 2019 - 2021, samples were collected during general river baseflow conditions (July –...

This data release is part of a cooperative study to assess streamflow availability under low-flow conditions for streams on the island of Hawai'i and West Maui from 2021 to 2022. This data release contains seven child items that consist of the following files: (1) a metadata xml file describing the data release files and data attributes, (2) an annotated NWIS-Mapper screen-captured image...
Riverbank vertical temperature profiler data and calculated groundwater discharge flux estimates from the Farmington River corridor, CT, USA Riverbank vertical temperature profiler data and calculated groundwater discharge flux estimates from the Farmington River corridor, CT, USA
As the climate warms and dry periods become more extreme, shallow groundwater discharge is generally becoming a less reliable source of streamflow while deep groundwater discharge remains a more resilient source. The implications of shifts in the relative balance of shallow and deep groundwater discharge sources are profound in gaining streams. These different sources exert critical...
