Digital Representation of Isopach Maps for Selected Geologic Periods from an Atlas Published by Sloss and others (1960) Digital Representation of Isopach Maps for Selected Geologic Periods from an Atlas Published by Sloss and others (1960)
Information of hydrogeologic and geologic importance from the book, "Lithofacies Maps: An Atlas of the United States and Southern Canada" (Sloss and others, 1960) detailing geologic periods, including the Cambrian, Ordovician, Silurian, and Devonian were digitized from scanned maps. Isopach contours were captured and, along with Geologic Map of North America (GMNA) information (Garrity...
Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings Summary of Responses at the 2021 Colorado River Basin Science and Technology Meetings
In June and July 2021, the Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST) pilot team held a series of 12 Science and Technology Collaboration meetings with U.S. Geological Survey science staff to discuss complex integrated science challenges and solutions related to drought in the Colorado River Basin. These meetings were structured to explore...
X-ray diffraction data and estimates of mineral abundances based on Rietveld refinement for mine wastes collected through the USGS Earth Mapping Resources Initiative (ver. 3.0, June 2026) X-ray diffraction data and estimates of mineral abundances based on Rietveld refinement for mine wastes collected through the USGS Earth Mapping Resources Initiative (ver. 3.0, June 2026)
Powder X-ray diffraction (XRD) data and estimates of mineral abundances determined using Rietveld refinement included in this data release were generated as part of the Earth Mapping Resources Initiative (Earth MRI; https://www.usgs.gov/special-topics/earth-mri). Earth MRI is a partnership between the U.S. Geological Survey (USGS) and State geological surveys and was developed by the...
Molecular resources combined with morphology and geography to provide insights into the evolutionary history of a wide-ranging freshwater mussel species complex (Unionida: Quadrula) Molecular resources combined with morphology and geography to provide insights into the evolutionary history of a wide-ranging freshwater mussel species complex (Unionida: Quadrula)
The freshwater mussel Quadrula quadrula of eastern North America occupies several isolated river drainages along the coastal Gulf of Mexico and northward in the Mississippi Basin and Great Lakes. Previous work has documented high morphological and genetic variation across its range but due to paraphyly of mitochondrial barcodes, variants are currently recognized as conspecific. Here we...
Mercury concentrations in amphibian tissues and egg masses, fish tissues and sediment in subarctic, freshwater systems near Churchill, Manitoba, 2015-2019 Mercury concentrations in amphibian tissues and egg masses, fish tissues and sediment in subarctic, freshwater systems near Churchill, Manitoba, 2015-2019
Comma-separated values (.csv) files containing data related to amphibian, fish, and sediment sampling near Churchill, Manitoba between 2015-2019. Data files contain mercury concentrations in amphibian and fish tissues, amphibian egg masses, and sediment, as well as amphibian and fish morphometrics, life stage, site distance to coast and biome where the samples were collected.
Specific conductance and fiber-optic distributed temperature sensing data collected at Operable Unit 2, North Chevalier Field Disposal Area (Site 11), Naval Air Station Pensacola, Florida, 2018-2022 Specific conductance and fiber-optic distributed temperature sensing data collected at Operable Unit 2, North Chevalier Field Disposal Area (Site 11), Naval Air Station Pensacola, Florida, 2018-2022
This data release consists of two datasets, each accessible in its own child page, collected at the North Chevalier Field Disposal Area (Site 11) at Naval Air Station Pensacola in Florida. Site 11 is adjacent to Bayou Grande, which empties into Pensacola Bay. The first dataset consists of fiber-optic distributed temperature sensing data collected from March 13-March 16, 2018. The second...
Toxic Elements Found in Keratin, Liver, and Kidney of Ill, Dying, and Freshly Dead Agassiz’s Desert Tortoises (Gopherus agassizii) from the Mojave and Colorado Deserts of California between 1993 and 2000 Toxic Elements Found in Keratin, Liver, and Kidney of Ill, Dying, and Freshly Dead Agassiz’s Desert Tortoises (Gopherus agassizii) from the Mojave and Colorado Deserts of California between 1993 and 2000
The single database is in an excel file and includes data on elements occurring in keratin, liver, and kidneys of 46 Agassiz’s desert tortoises salvaged from the Mojave and Colorado deserts of California between 1993 and 2000.
Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane) Modeled habitat suitability for Erigeron rhizomatus (Zuni fleabane)
This raster presents the final outputs from a VisTrails/SAHM workflow to model the potential distribution of Zuni fleabane (Erigeron rhizomatus) in northwestern New Mexico. These models utilized field data of spatially thinned occurrence locations and random background locations. We included a suite of predictors related to soils, topography, vegetation cover, and geology. Details about...
Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States Sentinel-2 ACOLITE-DSF Aquatic Reflectance for the Conterminous United States
This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the Atmospheric Correction for OLI “lite” (ACOLITE). Aquatic reflectance, noted Rhow in ACOLITE documentation, is defined here as unitless water-leaving radiance reflectance and represents the ratio of water...
Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park
This data release compiles radiometric data, photographs, and descriptive collection information (location, elevation, etc.) for late Holocene sub-fossil Acropora palmata and A. cervicornis coral samples collected from the coral reefs of Dry Tortugas National Park, Florida (DRTO) from 2015 to 2023. The samples were collected under scientific research permits from the U.S. National Park...
Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022 Conterminous U.S. data used for modeling non-native vascular plant first records 1780-2022
This dataset was used for modeling the spatial distribution of first records of non-native plants in the conterminous U.S. The input dataset (alldata_input_frdm.csv) contains 4,763 rows of data, representing 1,538 counties in the contiguous U.S., 25 decades, and 3,389 first records of invasive terrestrial plant species (Williams et al., 2024) found in the US-RIIS list (Simpson et al...
Pathology of lesions in corals from the US Virgin Islands data release Pathology of lesions in corals from the US Virgin Islands data release
Stony coral tissue loss disease (SCTLD) was first documented in Florida in 2014 and has since spread through the Caribbean causing unprecedented mortality in over 20 species of corals. The cause of SCTLD is unknown, but bacteria are suspected based on regression of gross lesions in some corals treated with antibiotics. Limited pathology studies on SCTLD exist, but it is likely that...
