Enhanced Terrain Imagery of the Honesdale 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Honesdale 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Honesdale 30 x 60 minute quadrangle in Pennsylvania and part of New York. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter resolution lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different...
Suspended Sediment and Water Temperature Data in the Suiattle River and the Downey Creek Tributary, Washington for select time periods over 2013 - 2017 Suspended Sediment and Water Temperature Data in the Suiattle River and the Downey Creek Tributary, Washington for select time periods over 2013 - 2017
This data release provides suspended-sediment (concentration and load) and water temperature data for two locations along the Suiattle River (USGS 1217900 and 12188380) and a tributary, Downey Creek (USGS 1217985) in Washington State for partial periods over 2013-2017. Suspended-sediment and water temperature data were collected over two summer seasons from May through September 2016 and...
Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos) Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos)
This data set is composed of data collected from an experimental study inoculating mallard ducks (Anas platyrhynchos) with Saxitoxin and associated control ducks. Data includes the specific of inoculation, observational behavioral data, daily weights, dosing, results of inoculation, testing of samples collected throughout the study, and necropsy results.
2020 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York (ver. 2.0, February 2024) 2020 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York (ver. 2.0, February 2024)
This U.S. Geological Survey data release provides surface-water quality, streamflow, and groundwater-elevation data collected within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2019 through September 30, 2020. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a five-year...
Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA
To aid in geologic studies of sediment transport and environmental change of a coastal marsh, 1-centimeter (cm) foraminiferal subsamples were taken from seven sediment push cores collected in the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi (MS), in October 2016. The push cores were collected along two, shore-perpendicular transects at 5, 15, 25, and 50 meters (m)...
Mississippi National River and Recreation Area (MISS) Multibeam Bathymetry, Hillshades, and Sidescan Image Mosaics; River Velocity and Bed Composition Mapping for Hidden Falls Mississippi National River and Recreation Area (MISS) Multibeam Bathymetry, Hillshades, and Sidescan Image Mosaics; River Velocity and Bed Composition Mapping for Hidden Falls
The National Park Service's (NPS) Mississippi National River and Recreation Area (MISS) and the St. Croix National Scenic Riverway (SACN) have established high value habitat corridors for threatened and endangered native mussels, including the Winged Mapleleaf and Higgins’ Eye Pearlymussel. Underwater sonar, a hydroacoustic remote sensing technology, is a valuable tool for mapping...
St. Croix National Scenic Riverway (SACN): Sonar Data Mapping to Assess Native Mussel Habitat St. Croix National Scenic Riverway (SACN): Sonar Data Mapping to Assess Native Mussel Habitat
The National Park Service (NPS) partnered with the U.S. Geological Survey (USGS) to collect hydroacoustic data of the Saint Croix River for the development of high-resolution bathymetry and sidescan imagery. The combined datasets will provide key components to characterizing benthic habitat. These information needs were highly desired by the NPS to more accurately assess environmental...
Pathogen and Contaminant Exposure Data from Southern Beaufort Sea Polar Bears, 2007-2014 Pathogen and Contaminant Exposure Data from Southern Beaufort Sea Polar Bears, 2007-2014
These were data collected from polar bears from the Southern Beaufort Sea during the spring between 2007 and 2014. Data include individual ID, capture date, sex and age class, whether individuals visited bowhead whale carrion sites, exposure status relative to five pathogens, and concentrations of certain persistent organic pollutants.
Hydrologic, water-quality, fire, forest-cover, and other data, the Great Dismal Swamp, Virginia and North Carolina Hydrologic, water-quality, fire, forest-cover, and other data, the Great Dismal Swamp, Virginia and North Carolina
The Great Dismal Swamp (the swamp) is a forested peatland in southeastern Virginia and northeastern North Carolina. Since early colonial times, timber harvesting and drainage through a network of ditches constructed to facilitate the harvesting have altered these ecosystems. The U.S. Fish and Wildlife Service has managed the swamp as the Great Dismal Swamp National Wildlife Refuge since...
Imagery, soil temperature and humidity profiles, and meteorological data from December 2020 to April 2021, Grand Falls Dune Field, Arizona Imagery, soil temperature and humidity profiles, and meteorological data from December 2020 to April 2021, Grand Falls Dune Field, Arizona
Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, smaller dunes, and ripples, and is bimodal in composition. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic grains) is locally sourced from nearby cinder cones [1]...
Environmental DNA data, fish abundance data, and stream habitat data from northwest Montana and northeast Washington and southern British Columbia, Canada Environmental DNA data, fish abundance data, and stream habitat data from northwest Montana and northeast Washington and southern British Columbia, Canada
Field estimates of the abundance of two trout species (bull trout and westslope cutthroat trout) in Montana and rainbow trout in Washington and British Columbia were collected in concert with environmental DNA samples (eDNA) to evaluate if eDNA copy numbers correlated with abundance of trout. In addition, stream habitat data including channel units (pools, riffles), substrate, large...
Point Sampling Data for Eelgrass (Zostera marina) and Seaweed Distribution and Abundance in Bays Adjacent to the Izembek National Wildlife Refuge, Alaska Point Sampling Data for Eelgrass (Zostera marina) and Seaweed Distribution and Abundance in Bays Adjacent to the Izembek National Wildlife Refuge, Alaska
These data are in nine tables relating to surveys of eelgrass beds in Izembek and Kinzarof Lagoons, Izembek National Wildlife Refuge, Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass.
