"Luminescence Data from Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington and the Walllula fault at Finely Quarry, Washington" "Luminescence Data from Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington and the Walllula fault at Finely Quarry, Washington"
This data release presents optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL) measurements from sediment samples collected at Quaternary fault exposures in central and southeastern Washington. The primary focus of the dataset is luminescence data from three paleoseismic trenches excavated across the Dead Coyote fault scarp in the Kittitas Valley, central...
Pallid Sturgeon (Scaphirhynchus albus) Free Embryo Drift and Dispersal Experiment Associated with the Fort Peck Dam Flow Test in the Upper Missouri River, Montana, June 2024 Pallid Sturgeon (Scaphirhynchus albus) Free Embryo Drift and Dispersal Experiment Associated with the Fort Peck Dam Flow Test in the Upper Missouri River, Montana, June 2024
The data set contains sampling and catch data associated with an experiment to examine dispersal and short-term survival of endangered pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River of eastern Montana. The experiment was conducted as part of a flow test from Fort Peck Dam, when warm surface water from Fort Peck reservoir was released over the spillway to...
Metabarcoding data of the fish community within Tuckahoe Creek, a tributary of the James River, Virginia, USA. Metabarcoding data of the fish community within Tuckahoe Creek, a tributary of the James River, Virginia, USA.
Electrofishing is currently the most common method used to assess freshwater fish communities. Although conventional electrofishing practices are considered effective there are inherent limitations. One alternative method for evaluating fish assemblage dynamics is the sequencing of environmental DNA (eDNA) extracted from water samples. Although eDNA sampling has become more common in...
GIS Data for Reconnaissance Geologic Map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana GIS Data for Reconnaissance Geologic Map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the reconnaissance geologic map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana (Toth, 1983). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic...
NHDPlus V2 Elevation Derivatives for the Conterminous United States NHDPlus V2 Elevation Derivatives for the Conterminous United States
This metadata record documents four 30-meter raster data layers; 1) elevation, 2) hydro-enforced elevation, 3) flow direction, and 4) flow accumulation for the conterminous United States. The datasets are derived from the NHDPlus Version 2.1 regional raster datasets and presented here as Cloud Optimized GeoTIFFs (COGs).
Floodplain Forest Response to Multiple Large-Scale Inundation Events Survey Data From Eight Pools of the Upper Mississippi River Collected During the Growing Seasons of 1995 and 2021 Floodplain Forest Response to Multiple Large-Scale Inundation Events Survey Data From Eight Pools of the Upper Mississippi River Collected During the Growing Seasons of 1995 and 2021
Throughout the Upper Mississippi River System (UMRS), floods in 1993 and 2019 were record-setting events in terms of flood stage and duration of flooding. Floodplain tree species are adapted to survive moderate frequencies, intensities, and durations of inundation. These events generated interest in quantifying levels of tree mortality and presented an opportunity to study how...
