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)
This dataset consists of raw survey data from nighttime call surveys for anurans collected as part of a series of surveys targeting Blanchard's cricket frog (Acris blanchardi) in 2024 in the upper Midwest, United States of America. Anuran communities were surveyed during the night using parabolic microphones or naked ear with multiple observers surveying sites independently over several...
Data and Code Release: Comparison of Recovery Rates from Rapid DNA Extraction Kits for Point of Use eDNA Detection Data and Code Release: Comparison of Recovery Rates from Rapid DNA Extraction Kits for Point of Use eDNA Detection
We evaluated extraction efficiency of four DNA rapid extraction protocols using filters spiked with primary cultured grass carp (Ctenopharyngodon idella) gill cells. The extraction methods included two syringe-based column extractions, an extraction solution, and a Chelex extraction protocol alongside a laboratory-based spin column kit. We estimated DNA yield using a newly designed...
GIS Data for Geologic Map of Precambrian Rocks of the Sierra Madre, Carbon County, Wyoming and Jackson and Routt Counties, Colorado GIS Data for Geologic Map of Precambrian Rocks of the Sierra Madre, Carbon County, Wyoming and Jackson and Routt Counties, Colorado
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the Geologic map of Precambrian rocks of the Sierra Madre, Carbon County, Wyoming, and Jackson and Routt Counties, Colorado (Houston and Graff, 1994). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the...
DNA sequences used to analyze evolutionary rates of transient receptor potential (Trp) genes in tetrapods DNA sequences used to analyze evolutionary rates of transient receptor potential (Trp) genes in tetrapods
The dataset consists of two file types. The first type consists of sets of orthologous gene sequences of the transient receptor potential (Trp) superfamily of genes in FASTA format. The sequence data were obtained from the Gene database of the National Center for Biotechnology Information (NCBI, www.ncbi.nlm.nih.gov/gene), aligned at the codon level, and trimmed to a defined region...
Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2024 Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2024
The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water for use in agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer...
