Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022 Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022
In February 2022, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft systems (UAS) remote sensing flights to support biological soil crust (biocrust) research at an experiment site located near Castle Valley, Utah. Researchers at the USGS Southwest Biological Science Center have managed this site for over 50 years to study the effects of
Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada
Northern deltas receive chromophoric dissolved organic matter (CDOM) from their watersheds, which can be oxidized to carbon dioxide upon absorption of sunlight (i.e., photomineralized). These deltas also receive total suspended solids (TSS), which may shade sunlight absorption by CDOM, thus limiting photomineralization. To quantify this interaction for the first time, we measured
Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado
This data release presents geologic map data for the bedrock geology of the Aztec 1-degree by 2-degree quadrangle, New Mexico. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital...
Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin
This data release hosts detrital zircon U-Th-Pb geochronology data that were created to support geologic mapping and research in the context of the Geologic Framework of the Intermountain West Project supported by the National Cooperative Geologic Mapping Program. These data characterize the deposition age and provenance of Cretaceous stratigraphic units exposed in the Piceance Creek...
Luminescence Data For: Vibracores Collected in 2021 from the Central Florida Gulf Coast Barrier Islands Luminescence Data For: Vibracores Collected in 2021 from the Central Florida Gulf Coast Barrier Islands
This report summarizes the dating results from sedimentary deposits sampled by the St. Petersburg 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...
Digital Data of Structural Contours from Previously Published USGS Mississippi Embayment Studies Digital Data of Structural Contours from Previously Published USGS Mississippi Embayment Studies
This digital dataset is a result from the goal within the U.S. Geological Survey’s (USGS) National Cooperative Geologic Mapping Program to convert surficial data that were previously published in non-digital format to digital, vector-based data suitable for use by the public and in USGS studies. The objective of the data conversion is to reproduce the original published mapping with...
Data release for An early Holocene wet period from the southwestern U.S. Data release for An early Holocene wet period from the southwestern U.S.
Multiple generations of spring-fed streams traversed ~800 km2 of the Las Vegas Valley in southern Nevada between ~10.9 and 8.5 ka, depositing an extensive tufa network. The scale of this network and diversity of tufa morphologies is novel in North America and offers an opportunity to obtain quantitative paleoclimate data for the region during the early Holocene. We determined isotopic...
Digital data of isopach contours and salt extent boundaries from previously published Regional Aquifer System Analysis (RASA) studies on the Northern Great Plains of Wyoming, North Dakota, South Dakota, Montana, and Nebraska Digital data of isopach contours and salt extent boundaries from previously published Regional Aquifer System Analysis (RASA) studies on the Northern Great Plains of Wyoming, North Dakota, South Dakota, Montana, and Nebraska
This GIS dataset presents contours and maps from previously published interpretations of hydrogeologic units of the northern Great Plains by Downey (1986). The original source publication was completed as a component of the United States Geological Survey’s (USGS) Regional Aquifer System Analysis (RASA) professional paper series. Isopach contour maps in this study delineate the upper...
Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city. Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city.
Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land use segregation vary over years, these maps provide an important spatial lens in determining how patterns of segregation spatially and temporally developed during the course of the past century. Using a high-resolution land...
USGS Isotope: A Database of Radiogenic and Stable Isotopic Data USGS Isotope: A Database of Radiogenic and Stable Isotopic Data
USGS Isotope is a database of compiled radiogenic and stable isotopic data from rocks and critical mineral deposits. The data set contains published elemental concentrations, isotopic ratios, analytical information, sample metadata including location, and source citations. Analytical techniques represented include Sm-Nd, U-Th-Pb, Rb-Sr, Lu-Hf, Re-Os, O, and S isotopic systems. Data...
Isotopic data and trace element data for siliceous sinter geyserite deposits, El Tatio Geyser Field, Chile Isotopic data and trace element data for siliceous sinter geyserite deposits, El Tatio Geyser Field, Chile
This dataset contains U-Th isotope ratios and trace element abundances for hydrothermal siliceous sinter deposits from several geyser localities in El Tatio Geyser Field, Chile.
Data release of U-Pb TIMS zircon and monazite geochronology for Proterozoic rocks of the Mojave Province, California and Nevada, USA Data release of U-Pb TIMS zircon and monazite geochronology for Proterozoic rocks of the Mojave Province, California and Nevada, USA
This U.S. Geological Survey (USGS) data release presents U-Th-Pb concentrations, isotopic ratios, and geochronologic data collected by thermal ionization mass spectrometry (TIMS) for Proterozoic igneous and metamorphic rocks of the Mojave Province, California and Nevada, USA. Sample and data collection occurred by 1984 and 1990.
