Geochemical and mineralogical data for Upper Devonian gray, black, and pyritic black shales from the Appalachian Basin Geochemical and mineralogical data for Upper Devonian gray, black, and pyritic black shales from the Appalachian Basin
Geochemical and mineralogical characterization data was collected for samples of the Upper Devonian Hanover and Dunkirk Formations from outcrops in the Appalachian Basin (Chautauqua County, New York). The data was integrated with outcrop descriptions in a publication (see larger work) that describes the enrichment of particular trace metals and minerals in different shale types formed...
North American dataset of ecosystem properties in tidal saline wetlands—Canopy height, aboveground biomass, productivity, soil carbon density, and soil carbon accumulation North American dataset of ecosystem properties in tidal saline wetlands—Canopy height, aboveground biomass, productivity, soil carbon density, and soil carbon accumulation
This dataset includes literature-derived ecological data from tidal saline wetlands across the United States, Canada, and Mexico for the following ecosystem properties: canopy height, aboveground biomass, productivity, soil carbon density, and soil carbon accumulation rates.
Database for the geologic map of the Frederick 30 x 60 quadrangle, Maryland, Virginia, and West Virginia Database for the geologic map of the Frederick 30 x 60 quadrangle, Maryland, Virginia, and West Virginia
The database for the geologic map of the Frederick 30 x 60 quadrangle covers the distinct geologic provinces and sections of the central Appalachian region that are defined by unique bedrock and resulting landforms. From west to east, the provinces include the Great Valley section of the Valley and Ridge province, the Blue Ridge province, and the Piedmont province; in the extreme...
Movements of Black Brant Tagged While Molting in the National Petroleum Reserve - Alaska Movements of Black Brant Tagged While Molting in the National Petroleum Reserve - Alaska
This data release contains five tables of information related to the movement patterns of Black Brant equipped with high-frequency GPS tags: 1) brant banding records, 2) helicopter flight routes for experimental disturbance trials, 3) Brant movement data from Milsar tags deployed in 2023, 4) Brant movement data from Milsar tags deployed in 2024, and 5) Brant movement data from Ornitela...
2025 Wetland Accretion Measurements from Smithsonian Environmental Research Center SMARTX Warming Plots 2025 Wetland Accretion Measurements from Smithsonian Environmental Research Center SMARTX Warming Plots
Sediment accretion measurements were made at the SMARTX warming experiment at the Smithsonian Environmental Research Center's Global Change Research Wetland. Feldspar marker horizons were established at the beginning of the experiment in 2016 in the warming plots, and were subsequently buried over time by wetland accretion of both organic and inorganic matter. These data include the...
Understanding mechanisms for Brook Trout persistence in warming streams: what stream temperatures do fish actually experience? Understanding mechanisms for Brook Trout persistence in warming streams: what stream temperatures do fish actually experience?
As stream temperatures increase, cold water adapted brook trout populations are projected to decline. However, there are mechanisms brook trout can use to persist in warming streams. Those mechanisms include acclimation, adaptation, and utilizing cold water refugia in streams where thermal heterogeneity is high. Using implanted temperature recording tags, this study examines individual...
Groundwater-quality data in the Western Slope of the Sierra Nevada Domestic-Supply Aquifer Study Unit, 2024: Results from the California GAMA Priority Basin Project (ver. 1.2, March 2026) Groundwater-quality data in the Western Slope of the Sierra Nevada Domestic-Supply Aquifer Study Unit, 2024: Results from the California GAMA Priority Basin Project (ver. 1.2, March 2026)
The U.S. Geological Survey collected groundwater samples from 38 wells used for domestic and small system drinking water supplies in the south-central Sierra Nevada region, California in 2023 and 2024. The wells were sampled for the Western Slope of the Sierra Nevada domestic-supply aquifer study unit of the California Groundwater Ambient Monitoring and Assessment Program Priority Basin...
Global gray-sky dT (Version 2): inverse of the surface psychrometric constant parameter in the SSEBop evapotranspiration model Global gray-sky dT (Version 2): inverse of the surface psychrometric constant parameter in the SSEBop evapotranspiration model
The surface psychrometric constant (spc) is a key model parameter in actual evapotranspiration (ET) modeling using the Operational Simplified Surface Energy Balance (SSEBop) model for establishing model boundary limits for the dry/bare and wet/vegetated surface conditions. The inverse of the constant (1/spc) represents the temperature difference (dT) between the bare/dry surface and the...
Coastal Multibeam Bathymetry and Backscatter Data Collected in June 2024 From Wallops and Assawoman Islands, Virginia Coastal Multibeam Bathymetry and Backscatter Data Collected in June 2024 From Wallops and Assawoman Islands, Virginia
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Wallops and Assawoman Islands, Virginia (VA). During this study, multibeam bathymetry data were collected aboard the Research Vessel (R/V) Sallenger from June 1-13, 2024, as a part of field activity number (FAN) 2024-310...
Tailwater time series and telemetry receiver range testing data for Kentucky Dam between 2021 and 2022 Tailwater time series and telemetry receiver range testing data for Kentucky Dam between 2021 and 2022
Invasive carp residency patterns in dam tailwaters are poorly understood. To better inform removal efforts in dam tailwaters, we examined multiple predictors of invasive carp residency in the Kentucky Dam tailwater between 2021 and 2022. This data release contains a time series dataset with daily counts and daily mean residence times of Silver Carp (Hypophthalmichthys molitrix) recorded...
Amphibian nighttime call data from Midwest ARMI surveys 2003-2008 (ver. 1.1, April 2026) Amphibian nighttime call data from Midwest ARMI surveys 2003-2008 (ver. 1.1, April 2026)
This dataset consists of raw survey data from nighttime call surveys for anurans collected as part of several separate projects from 2003 to 2008. Anuran communities were surveyed during the night using parabolic microphones or naked ear with multiple observers conducting surveys. Data are presented from each survey. First release: 2025 Revised: April 2026 (ver. 1.1)
Amphibian nighttime call data from Midwest ARMI cricket frog surveys 2024 (ver. 1.1, April 2026) Amphibian nighttime call data from Midwest ARMI cricket frog surveys 2024 (ver. 1.1, April 2026)
