Data

This data release presents field and laboratory rock magnetic measurements from rocks from the Blanca Peak region of the Sangre de Cristo Range in southern Colorado. These data include averages of magnetic susceptibility from 2 to 12 measurements per site made with a handheld meter, quantifying magnetic contrasts between rock units that could be detected in geophysical surveys...

The U.S. Geological Survey’s National Geologic Synthesis Project is engaged in data preservation and compilation across the United States. As a part of this broader effort, this data release serves digitized structure contour, isopach, and fault lines from a series of previously published maps of the Palo Duro Basin and the surrounding uplifts within the Texas Panhandle (Dutton 1980...

This data release contains eight luminescence samples collected for USGS Science Investigations Map, "Quaternary geologic map of the Mesquite Springs fault zone, San Bernardino County, California", of the Mesquite Hills (north of Ludlow CA about halfway between I-15 and I-40). The samples were analyzed by infrared stimulated luminescence (IRSL) and produced ages between ~33 ka and ~200...

This data release contains traditional and portable optically stimulated luminescence (OSL) data collected from the Stinking Water Creek Basin near Rangely, Colorado, to constrain the timing of alluvial deposition and channel evolution in landscapes underlain by the Late Cretaceous Mancos Shale. The dataset includes OSL measurements from fluvial terraces, modern stream channels, and...

This Data Release summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Hazards Team and analyzed at the USGS Luminescence Geochronology Laboratory. During field seasons 2023 and 2024, these samples were collected as part of the Abandoned Mine Lands Task of the Intermountain West Geologic Framework project, in collaboration with the Navajo Nation and USGS...

The following report summarizes the dating results from sedimentary deposits discovered during paleoseismic investigations of Puerto Rico. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations. We...

Characterizing spatial uncertainty in satellite-derived burned area products is essential to accurately represent fire activity and manage fire-prone ecosystems. However, most product evaluations rely on summary statistics, where their use to adjust burned area estimates is unclear. This dataset provides a comprehensive characterization of the spatial and temporal uncertainty in the...

Because urban landscapes are heterogeneous, the methods and spatial resolution used to depict the land surface greatly influence the representation of urban features. Land cover products such as tree canopy cover (TCC) are particularly sensitive to the methodology and resolution used in their creation. Differences in TCC mapping have implications on the outcomes of ecosystem service (ES)...

Surface water storage, including wetlands and lakes, is not typically considered in hydrological model calibrations. We tested a multivariate calibration process (Latin Hypercube Sampling), incorporating Sentinel-1/2 surface water storage, for a Soil and Water Assessment Tool model across the 0.5 million km^2 Upper Mississippi River Basin. While 19% of the 2000 parameter sets adequately...

The ~21 m deep Mammoth Site (MS) bone bed site at Hot Springs, South Dakota, provides a unique opportunity to reconstruct paleoenvironmental conditions on the northern Great Plains of the United States. Past published radiocarbon analyses of mammoth bones found within the MS sinkhole suggested they were deposited ~23-42 ka. However, two U-series ages ranging between 129-150 ka and a

The Black Warrior Basin is a sedimentary foreland basin in western Alabama and northern Mississippi. This basin is named after the Black Warrior River and is developed extensively for coal, coalbed methane, conventional oil, and natural gas production. Its geologic genesis was due to Paleozoic tectonic events between the Appalachian and Ouachita orogenic belts. The Paleozoic rock hosts...

Globally, many waterbodies and floodplains have been lost, degraded, or are at risk for further loss, which may have unintended consequences for rivers, including exacerbating flood and drought conditions. We explored how including surface water storage time series in deep learning models influences our ability to predict river discharge. We utilized Sentinel-1 and Sentinel-2 algorithms...
