Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA Radiocarbon, U-series, and amino acid chronology data for late Quaternary marine terraces in coastal Santa Barbara County, California, USA
In several early studies, central California marine terraces between Santa Barbara and Point Conception were interpreted to record sea-level high stands of the last interglacial complex, ~80 ka to ~120 ka (marine isotope stage [MIS] 5). These ages and their elevations (~20 m to ~45 m) indicate modest rates of tectonic uplift, similar to those from other localities in southern and central
Luminescence Data For Floodplain Carbon Storage: Soil Organic Carbon, Surface Age, and Vegetation in an Icy River Corridor Luminescence Data For Floodplain Carbon Storage: Soil Organic Carbon, Surface Age, and Vegetation in an Icy River Corridor
Rivers are some of the most dynamic features of the Arctic landscape, yet their role in the global carbon cycle is poorly understood. Researchers are still unraveling the intricacies of how river dynamics control organic carbon (OC) accumulation, transport, and degradation in riverine systems. The interplay between permafrost thermal state in river corridors, snow and ice-affected...
Luminescence Data for the Geomorphological Evolution of the Provincetown Hook, Cape Cod, Massachusetts Luminescence Data for the Geomorphological Evolution of the Provincetown Hook, Cape Cod, Massachusetts
These Holocene aged samples are from three sediment cores obtained near the Provincetown Hook spit in Cape Cod, Massachusetts. The goal of the geochronology work is to determine when shoreface sediments, which represent the oceanward extent of the spit, were present at the surface for the Provincetown Hook. Results from this work support efforts to publish more recent sedimentological...
Multiproxy paleoecological data from Santa Fe Lake, NM Multiproxy paleoecological data from Santa Fe Lake, NM
This data release contains paleoecological records from Santa Fe Lake, NM USA. Santa Fe Lake is a small (1.4 ha), subalpine lake in the Sangre de Cristo Mountain Range of the Southern Rocky Mountains (35.79°N, 105.78°W, 3532 m a.s.l). Overlapping sediment cores were taken from Santa Fe Lake in September, 2020 in 5.4 m of water from a coring platform with a Livingstone square-rod piston...
Compilation and recalculation of Cretaceous-Miocene intrusive igneous crystallization geochronology from the northern Rocky Mountains, Montana and Idaho, USA Compilation and recalculation of Cretaceous-Miocene intrusive igneous crystallization geochronology from the northern Rocky Mountains, Montana and Idaho, USA
This dataset presents a recalculated compilation of geochronology ages of Cretaceous-Miocene intrusive rocks and volcanic plugs in the northern Rocky Mountains USA, with a focus on Montana and Idaho. Mineral assessments and prospectivity mapping requires detailed spatiotemporal understanding of magma systems in the upper crust to predict when and where ore deposits may have formed...
Digital input data and model output for a three-dimensional hydrogeologic framework for the Great Basin carbonate and alluvial aquifer system of Nevada, Utah, and parts of adjacent states Digital input data and model output for a three-dimensional hydrogeologic framework for the Great Basin carbonate and alluvial aquifer system of Nevada, Utah, and parts of adjacent states
This digital dataset was created as part of a U.S. Geological Survey (USGS) regional groundwater assessment of the eastern Great Basin; the project was called the Great Basin Carbonate-Alluvial Aquifer Study (GBCAAS). The study area has a geographic extent of 110,000 square miles, predominantly in eastern Nevada and western Utah. As part of this larger study, the USGS developed digital...
Data Release - Geologic Map geodatabase of the valley corridor of the 59-mile reach of the Missouri National Recreational River, South Dakota, Nebraska, and Iowa: Gavins Point Dam to North Sioux City Data Release - Geologic Map geodatabase of the valley corridor of the 59-mile reach of the Missouri National Recreational River, South Dakota, Nebraska, and Iowa: Gavins Point Dam to North Sioux City
This geologic map area of 5,430 km2 spans a reach of the lower Missouri River valley and adjoining uplands for about 100 kilometers east of Gavins Point Dam, the easternmost mainstem dam on the Missouri River. Understanding the surficial geologic history of the valley is relevant to natural resource management of the Missouri National Recreational River and is foundational to improved
Data release for Remotely Sensed Surface Water Storage Shows Distinct Patterns from SWAT-Simulated Data (ver. 2.0, February 2026) Data release for Remotely Sensed Surface Water Storage Shows Distinct Patterns from SWAT-Simulated Data (ver. 2.0, February 2026)
Understanding and projecting the downstream benefits of terrestrial surface water storage, i.e., volumetric water stored in lakes and wetlands (SWstorage) requires watershed hydrologic models. Use of external datasets to calibrate and validate modeled SWstorage dynamics remains uncommon, particularly across major river basins. Here, we: (1) develop and assess the utility of a novel...
Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska
Loess is the most widespread surficial deposit in the state of Alaska. Although loess of last-glacial age is common in mid-continental North America, records of last-glacial loess in Alaska have been elusive. Here we report a record of last-glacial loess on the Seward Peninsula, along with studies of a transect of loess localities also thought to date to the last glacial period. Highly...
Wildfire building destruction and exposure in the conterminous United States, 2002-2022 Wildfire building destruction and exposure in the conterminous United States, 2002-2022
Wildfires pose a major threat to human life and property, but there is limited information for assessing numbers or precise locations of building losses at a national scale. This geospatial dataset was developed to identify point locations of all buildings destroyed by or exposed to major wildfire disasters from 2002-2022. The data include all wildfire events in the conterminous United...
Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina Geochronological Data for: Geologic Map of the Emporia Quadrangle, North Carolina
The Emporia 1:100,000-scale quadrangle straddles the Tidewater Fall Line in southern Virginia and includes a small part of northernmost North Carolina. Sediments of the coastal plain underlie the eastern three-fifths of this area. This data release contains geochronology from sediment samples collected in the eastern half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina...
Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA
Emergent marine terraces record past periods of relatively high sea level and are common on uplifting coasts worldwide. Such landforms are extensive around the Gulf of Corinth area of Greece and along the coast of California, USA. In the Gulf of Corinth region, marine terraces record Quaternary uplift due to ongoing basin extension on the northern side of the Africa-Eurasia-Aegean Sea...
