Detrital zircon U-Pb data for Upper Triassic sandstones of the Auld Lang Syne basin, northwest Nevada, USA Detrital zircon U-Pb data for Upper Triassic sandstones of the Auld Lang Syne basin, northwest Nevada, USA
This data release includes raw detrital zircon U-Pb data for isolated sandstones in Upper Triassic deposits of the Auld Lang Syne basin of northwest Nevada, USA. Detrital zircon U-Pb data for 11 sandstone samples (3269 zircon U-Pb dates) were acquired via LA-ICP-MS at the University of Arizona LaserChron Center for 11 sandstone samples. Primary insights from the data are twofold: 1) The...
Detrital Zircon U-Pb data from selected Appalachian rivers and Outer Banks-area coastal sediments Detrital Zircon U-Pb data from selected Appalachian rivers and Outer Banks-area coastal sediments
U-Pb isotopic data from zircon grains from the sediment bedload of seven modern rivers: the Susquehanna, Potomac, Roanoke, James, Peedee, Tar, and Cape Fear, as well as from three samples taken from beaches in Albemarle and Pamlico Sounds (North Carolina), two Pleistocene core samples, and three samples on the ocean-facing foreshore of the Outer Banks barrier islands (North Carolina and...
Development of High Surface Area Organosilicate Nanoparticulate Thin Films for Use in Sampling Hydrophobic Compounds in Sediment-Data Development of High Surface Area Organosilicate Nanoparticulate Thin Films for Use in Sampling Hydrophobic Compounds in Sediment-Data
The data set describes the characterization of organosilica nanoparticle thin films used to adsorb PCBs from laboratory water and a sediment collected near Anniston Alabama. Data not shown here for the porewater and sediment PCB concentrations can be found in Appendix 1 of Ingersoll et al. 2014 (http://dx.doi.org/10.3133/sir20135125) Bulk sediment chemistry was obtained from Table A1-3a...
Diatom Data from Coastal Environments on Montague Island, Alaska Diatom Data from Coastal Environments on Montague Island, Alaska
This dataset consists of fossil diatom counts from sediment cores collected in coastal environments on Montague Island, Alaska, and analyzed at Virginia Tech University.
Dictionary of Microsatellite Loci from the U.S. Geological Survey, Alaska Science Center, Molecular Ecology Laboratory Dictionary of Microsatellite Loci from the U.S. Geological Survey, Alaska Science Center, Molecular Ecology Laboratory
This data package provides a dictionary of microsatellite locus primers used by the USGS Alaska Science Center, Molecular Ecology Laboratory (MEL). It is a look-up file of microsatellite locus names and citations to the original publication or source where additional information about the locus primers may be found.
Digital 3D database of faulted horizons in the northern Arkoma basin, Arkansas Digital 3D database of faulted horizons in the northern Arkoma basin, Arkansas
This is a digital dataset to accompany the journal article "Influence of inherited structure on flexural extension in foreland basin systems: Evidence from the northern Arkoma basin and southern Ozark dome, USA", published in April 2024 by Earth Science Reviews. This dataset contains point features, line features, and raster grids that together constitute a 3D structural model of the...
Digital and NDVI images from Dwarf Cypress, Big Cypress National Preserve from 2021 to 2025 (ver. 2.0, June 2025) Digital and NDVI images from Dwarf Cypress, Big Cypress National Preserve from 2021 to 2025 (ver. 2.0, June 2025)
This data set includes images from Dwarf Cypress located within Big Cypress National Preserve. Images were taken multiple times daily from February 2021 to June 2024 using a five-band multispectral camera equipped for normalized difference vegetation index (NDVI) sensing and standard high-quality photographs.
Digital Archive of the R.S. Thompson western United States Packrat Midden Collection Digital Archive of the R.S. Thompson western United States Packrat Midden Collection
This data release provides a digital inventory of the Robert S. Thompson packrat midden collection consisting of 1,740 midden samples and subsamples primarily collected in the Great Basin region of Nevada, as well as in Arizona, California, Colorado, Oklahoma, Utah, and Washington, USA, by Robert S. Thompson (USGS scientist emeritus) and others between 1977 and 2006. Middens are waste...
Digital data for 3-D Geologic Framework and Textural Models for Cuyama Valley Groundwater Basin, California Digital data for 3-D Geologic Framework and Textural Models for Cuyama Valley Groundwater Basin, California
This digital dataset was created as part of a U.S. Geological Survey study in cooperation with the Santa Barbara County Water Agency to conduct a hydrologic resource assessment and develop an integrated numerical hydrologic model of the hydrologic system of Cuyama Valley, CA. As part of this larger study, the USGS developed this digital dataset of geologic data and three-dimensional...
Digital Data for a Three-Dimensional Geologic Map of the San Andreas Fault Zone Between Gold Hill and Pinnacles National Park, California Digital Data for a Three-Dimensional Geologic Map of the San Andreas Fault Zone Between Gold Hill and Pinnacles National Park, California
A three-dimensional geologic map was created by assembling eight geologic cross sections derived from geologic mapping, potential field geophysics, and petroleum well logs. The central feature of the map is the San Andreas Fault, with many other prominent structural features depicted that express the regional transpressional tectonic setting. The subsurface interpretation was based on...
Digital Data for Land and climate change in Mexico and Texas reveals small effects on migratory habitat of monarch butterflies (Danaus plexippus). Digital Data for Land and climate change in Mexico and Texas reveals small effects on migratory habitat of monarch butterflies (Danaus plexippus).
The decline of the iconic monarch butterfly in North America has motivated research on the impacts of land use and land cover (LULC) change and climate variability on monarch habitat and population dynamics. We investigated spring and fall trends in LULC, milkweed and nectar resources over a 20-year period, and ~30 years of climate variables in Mexico and Texas, a key region supporting...
Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon
Scoggins Dam in northwest Oregon lies within the Gales Creek fault zone (GCF), a northwest-striking system of active faults forming the boundary between the Coast Range and the Tualatin Valley about 25 km east of Portland, Oregon. Geologic mapping published in 2020 shows the dam to lie within a block-faulted releasing stepover between the right-lateral, NW-striking Scoggins Creek and...
