Microbial source tracking for streams in Scott County, Iowa, 2023

Surface water samples (n = 33) were collected in fall of 2023 at stream sites in Scott County Iowa, USA and were analyzed for microbial source tracking markers by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Microbial source tracking markers identify fecal sources of contamination by detecting microbes that are specific to certain anim

Simulations of larval fish transport and environmental conditions in Lake Michigan

Data files contain the simulated mean daily environmental conditions experienced by particles (which can be assumed to be planktonic larval alewife or yellow perch) in Lake Michigan during March 15 - July 31 of past and future years. Simulations were generated by integrating a series of climatic, hydrodynamic, biogeochemical, and Lagrangian particle dispersion (LPD) models. For each year, 42,765 p

Ungulate Migrations of the Western United States, Volume 4

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 4 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and planned for a

Laboratory analyses for fish tissue from Lake Koocanusa and Kootenai River Basin, Montana, 2022

This data release includes laboratory analyses for fish tissue samples collected from Lake Koocanusa and the Kootenai River Basin in Montana during 2022. Samples were collected by the U.S. Geological Survey Wyoming-Montana Water Science Center in cooperation with Montana Fish, Wildlife and Parks and Montana Department of Environmental Quality. Analyses include histology, percent moisture, and 30 e

Data release for climate change impacts on surface water extents across the central United States

High-frequency observations of surface water at fine spatial scales are critical to effectively manage aquatic habitat, flood risk and water quality. We developed inundation algorithms for Sentinel-1 and Sentinel-2 across 12 sites within the conterminous United States (CONUS) covering >536,000 km2 and representing diverse hydrologic and vegetation landscapes. These algorithms were trained on data

Shallow Coal Exploration Drill-Hole Data for Arkansas

Shallow (300 ft or less) coal exploration drill-hole data from 692 wells located in Arkansas are provided in this data release. The well locations extend over nine Arkansas counties and were drilled between 1975 and 1977, primarily by Phillips Petroleum Company (Phillips). Also included in the dataset are 79 wells drilled by Tenneco. The data were donated to the U.S. Geological Survey (USGS) in 20

Everglades mangrove vegetation data from 23 long-term plots (1992-2011)

Twenty-three long-term mangrove vegetation plots were established between 1992-1997 within the southwest coastal region of Everglades National Park (Florida, USA) to quantify tree damage and recovery following hurricanes and to understand the effects of global climate change. Many of the mangrove vegetation plots were associated with hydrology, soil porewater, and soil surface elevation monitoring

Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization

Biochar is a carbon-rich substance that is derived through the thermochemical conversion of biomass. Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis of selected

Digitized mangrove-marsh ecotone boundaries for Everglades National Park and Big Cypress National Preserve (Florida, USA) in 2013 and 2019

This dataset consists of a file geodatabase containing the digitized ecotone boundaries between mangroves and freshwater marsh in 2013 and 2019 at 14 systematically selected segments in Big Cypress National Preserve and Everglades National Park (southwest Florida, USA).

US non-native plant occurrence and abundance data and distribution maps for Eastern US species with current and future climate

This is a dataset containing aggregated non-native plant occurrence and abundance data for the contiguous United States. We used these data to develop habitat suitability models for species found in the Eastern United States using locations with 5% cover or greater. We adapted the INHABIT modeling workflow (Young et al. 2020), using a consistent set of climatic predictors that were important in th

Suspended Sediment Data and Loads in the Fountain Creek Watershed, CO

This data release consists of daily mean streamflow, daily mean suspended sediment concentration (SSC), and daily mean suspended sediment load (SSL) data for selected U.S. Geological Survey (USGS) streamgage sites within the Fountain Creek watershed, separated by water year. Each file also includes USGS approval levels and any associated qualifiers that were applied to the values. The daily mean S

CMIP6-LOCA2 threshold and extreme event metric projections from 1950-2100 for the Contiguous United States

Projections of extreme event metrics and threshold exceedances are produced by analyzing the Climate Model Intercomparison Program Phase 6 Localized Constructed Analogs (CMIP6-LOCA2) data set. The primary daily temperature and precipitation data are summarized to 36 annual metrics and 4 monthly metrics. This data set includes output from 27 GCMs for the period 1950-2100 under ssp245, ssp370, and s
