Luminescence and Radiocarbon Data for Quaternary activity of the Deadwood fault, west-central Idaho, U.S.A., 2021-2024 Luminescence and Radiocarbon Data for Quaternary activity of the Deadwood fault, west-central Idaho, U.S.A., 2021-2024
The Deadwood fault in the western Idaho Batholith in west-central Idaho, USA is a north-south trending zone of complex fault traces featuring minimal evidence of Quaternary movement. This data release contains luminescence and radiocarbon data from trench sediments exposed at Habit Creek and Trail Creek along the Deadwood Fault. The dataset includes 22 luminescence samples analyzed at...
Luminescence data associated with late Quaternary activity along the South Granite Mountains fault system, central Wyoming Luminescence data associated with late Quaternary activity along the South Granite Mountains fault system, central Wyoming
This dataset contains 21 traditional luminescence ages and ~900 portable optically stimulated luminescence (pOSL) measurements collected from the South Granite Mountains fault (SGMF) in central Wyoming. Traditional and portable luminescence techniques were used to help interpret colluvial wedge development, which support long recurrence intervals (13 to 68 ka) and a low late Quaternary...
Luminescence Data for Multiple Episodes of Quaternary Displacement on the Meeman-Shelby Fault, Eastern Arkansas Luminescence Data for Multiple Episodes of Quaternary Displacement on the Meeman-Shelby Fault, Eastern Arkansas
The luminescence data consists of 14 cores that provide the geochronology of the eastern principal fault of the Meeman-Shelby horst. The M-S fault has ~ 23 m of down-to-the-east displacement on the base of 16.2 ka Pleistocene alluvium, and 10 m of this displacement occurred between ~ 16.2 ka and ~ 12.7 ka, with an average vertical slip rate of 2.9 mm/yr. The base of the 12.7 ka Holocene...
Luminescence Data for: Decoding the Record of Sediment Availability from Barrier Island Geomorphology at Fire Island, New York Luminescence Data for: Decoding the Record of Sediment Availability from Barrier Island Geomorphology at Fire Island, New York
This report summarizes the dating results from sedimentary deposits sampled by the Coastal and Marine Science Center and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included as the supplementary material for any...
Luminescence and Radiocarbon Data for the Little Salmon Fault Zone within the Southern Cascadia Subduction Zone Luminescence and Radiocarbon Data for the Little Salmon Fault Zone within the Southern Cascadia Subduction Zone
The Little Salmon Fault zone (LSF) is a principal upper-plate fault within the SCSZ that daylights approximately 18-22 km above the shallowly dipping megathrust interface at latitude ~40.5°N. This data release contains luminescence data from five samples and radiocarbon data from fifteen samples collected from a fault-perpendicular trench across the LSF. These samples, which produced...
Luminescence, Radiocarbon, and Pollen data for a Geomorphic Investigation of the Chalk Hill Site, Northern Rodgers Creek Fault near Windsor, California Luminescence, Radiocarbon, and Pollen data for a Geomorphic Investigation of the Chalk Hill Site, Northern Rodgers Creek Fault near Windsor, California
Data release containing luminescence data for five samples, radiocarbon data for six samples, and one pollen count associated with three paleoseismic trenches at the Chalk Hill site on the northern section of the Rodgers Creek Fault, part of the dextral San Andreas fault system in northern California. We document at least three active fault strands of the northern Rodgers Creek Fault...
Luminescence Data for Holocene and Late Pleistocene surface faulting, Monument Hill fault, Red Rock Valley, southwest Montana Luminescence Data for Holocene and Late Pleistocene surface faulting, Monument Hill fault, Red Rock Valley, southwest Montana
This data release contains luminescence data associated with 10 samples collected to accompany detailed geomorphic mapping and interpretations of two paleoseismic trenches along the Monument Hill fault, a northwest-striking fault bounding the eastern Red Rock Valley in southwestern Montana. These optically stimulated luminescence ages, between >80 and 8 ka, provide new information to...
Source code for determining the optimal set of spatio-temporal features for predicting burn probability in the state of California, USA Source code for determining the optimal set of spatio-temporal features for predicting burn probability in the state of California, USA
Wildfires play a critical role in determining ecosystem structure and function and pose serious risks to human life, property and ecosystem services. Burn probability (BP) models the likelihood that a location could burn. Simulation models are typically used to predict BP but are computationally intensive. Machine learning (ML) pipelines can predict BP and reduce computational intensity...
Hyperspectral Uncrewed Aircraft Systems (UAS) Data Collected over Agricultural Crop Fields near Firebaugh, Central Valley, CA in August 2023 Hyperspectral Uncrewed Aircraft Systems (UAS) Data Collected over Agricultural Crop Fields near Firebaugh, Central Valley, CA in August 2023
In support of U.S. Geological Survey (USGS) Western Geographic Science Center researchers, the USGS National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft systems (UAS) hyperspectral remote sensing flights in the Central Valley of California over a variety of agricultural crop fields: cotton, almond, pistachio, grape, rice, and corn. A Headwall Nano-Hyperspec line scanning...
Date release for Humans experienced abrupt environmental changes at White Sands during the Last Glacial Maximum Date release for Humans experienced abrupt environmental changes at White Sands during the Last Glacial Maximum
Expanded excavations at White Sands National Park have unearthed 20 stratigraphic horizons containing in situ human footprints, megafaunal trackways, and linear features created by travois. Novel radiocarbon dating of conifer pollen, combined with ages of aquatic seeds, refines the chronology of the footprint-bearing sequence to between 23.5 and 21.7 ka. Biomarker, pollen, and...
Particle size and X-ray diffraction data for surficial samples collected on Etosha Pan, Namibia Particle size and X-ray diffraction data for surficial samples collected on Etosha Pan, Namibia
This data release provides particle-size and X-ray diffraction (XRD) data of sediment samples collected from dust emission "hot-spots" at Etosha Pan, Namibia. The dataset supports the investigation of the mineralogical, hydrological, and climatic controls on atmospheric dust emissions from ephemeral lake beds, which are globally significant sources of mineral dust aerosols. The particle...
Data Release for Geologic Framework and Hydrogeology of the Rico Rico and Nogales 7.5' quadrangles, Upper Santa Cruz basin, Arizona, with 3-Dimensional hydrogeologic model Data Release for Geologic Framework and Hydrogeology of the Rico Rico and Nogales 7.5' quadrangles, Upper Santa Cruz basin, Arizona, with 3-Dimensional hydrogeologic model
Rapid population growth and declining annual recharge to aquifers in the upper Santa Cruz basin area of southern Arizona, has increased the demand for additional groundwater resources. This demand is predicted to escalate in the future due to higher temperatures, longer droughts, less aquifer recharge, and decreased river and stream base flow. We conducted geologic studies to help...
