Large-Scale Marsh Creation Project – Upper Barataria Component Restoration (BA-0207) 2024 land-water classification Large-Scale Marsh Creation Project – Upper Barataria Component Restoration (BA-0207) 2024 land-water classification
The Louisiana State Legislature established the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to conserve, restore, create and enhance Louisiana's coastal wetlands. Restoration plans developed under CWPPRA require evaluating the effectiveness of each project in achieving long-term solutions to coastal wetlands loss. This data set includes mosaicked aerial photographs...
Late Miocene through Holocene Micropaleontologic collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California Late Miocene through Holocene Micropaleontologic collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California
This project has inventoried and produced a digital database of Late Miocene through Holocene micropaleontologic slides and data available in the USGS collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California. The digital database includes the location of samples, content of the samples, results of analyses, and other information in a format that can be...
Lead concentrations in snakes and soil near recreational and military shooting areas in Idaho Lead concentrations in snakes and soil near recreational and military shooting areas in Idaho
This dataset consists of lead concentrations of liver, anterior bone, and posterior bone from gophersnakes (Pituophis catenifer) and Great Basin rattlesnakes (Crotalus oreganus lutosus) found dead along roads in The Morley Nelson Snake River Birds of Prey National Conservation Area in southwestern Idaho, U.S.A. Because this area has been heavily impacted by both military and recreational...
Leaf and Root Trait Responses to Moderate and Severe Drought in Greenhouse‑grown Restoration Species Leaf and Root Trait Responses to Moderate and Severe Drought in Greenhouse‑grown Restoration Species
We assessed leaf and root morphological traits of seven species commonly used in restoration across the southwestern United States. Plants were grown in greenhouse conditions for four weeks followed by three weeks of growth under the following treatment conditions: control (adequate watering), moderate drought (12% soil volumetric water content), and severe drought (no water). Functional...
Limits of detection and quantification for several invasive carp environmental DNA (eDNA) assays Limits of detection and quantification for several invasive carp environmental DNA (eDNA) assays
Data describe the limits of detection (LOD), limits of quantification (LOQ), and associated quality assurance measurements of several environmental DNA (eDNA) assays for invasive black carp (Mylopharyngodon piceus), bighead carp (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), bigheaded carps (Hypophthalmichthys spp.), and grass carp (Ctenopharyngodon idella)...
Liquefaction potential index calculations at cone penetration test sites in California Liquefaction potential index calculations at cone penetration test sites in California
This data release provides tabulated liquefaction potential index (LPI) values for a standard set of earthquake magnitudes (M) in the range 4.5-9, peak ground accelerations (PGA) in the range 0-1.0 g, and groundwater depths (GWD) in the range 0-15 m, as described in detail in Engler and others (2025). We use these data to rapidly interpolate LPI values for any M-PGA-GWD combination. The...
Literature rates of measured methane fluxes from tidal wetland soils to the atmosphere Literature rates of measured methane fluxes from tidal wetland soils to the atmosphere
This data release reports a compilation of the literature that included measurements of both methane gas emission fluxes from the soil to atmosphere, and salinity, in different types of tidal wetlands around the globe. Rates were included for in situ measurements of methane flux in natural tidal wetlands but not experimental treatments or restored wetlands.
Loggerhead sea turtle single nucleotide polymorphism data for Dry Tortugas National Park, 2008 - 2016 Loggerhead sea turtle single nucleotide polymorphism data for Dry Tortugas National Park, 2008 - 2016
This release contains single nucleotide polymorphism (SNP) data derived from tissue and blood samples collected from 25 loggerhead individuals across nine years from the Dry Tortugas. Data are provided in FASTQ format, a text-based data structure supported by bioinformatics tools.
Long Island Sound nitrogen and phosphorus SPARROW models, with model inputs and outputs, 2000-2020 Long Island Sound nitrogen and phosphorus SPARROW models, with model inputs and outputs, 2000-2020
This data release contains model files for simulating seasonal estimates of total nitrogen (N) and total phosphorus (P) loads from watersheds draining to the Long Island Sound using a dynamic SPARROW (SPAtially Referenced Regressions On Watershed attributes) model. Input data, output predictions including prediction uncertainty, model control files, and model source code are provided to...
Los Angeles River Suspended Sediment Concentration Data, April 2021- November 2023 Los Angeles River Suspended Sediment Concentration Data, April 2021- November 2023
The Los Angeles River flows through a heavily urbanized area and the river is managed for multiple uses, including flood control, habitat, and recreation. The objective of this study was to collect data on stream flow and suspended sediment concentrations (SSC) at sites along the Los Angeles River and its tributaries in the Sepulveda Flood Control Basin (SFCB) to better understand...
Louisiana Barrier Island Comprehensive Monitoring Program – 2016–2021 habitat change, Chandeleur Islands Region Louisiana Barrier Island Comprehensive Monitoring Program – 2016–2021 habitat change, Chandeleur Islands Region
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...
