Fractional Estimates of Multiple Exotic Annual Grass (EAG) Species in the Sagebrush Biome, USA, 2016-2024 (ver. 5.0, July 2025) Fractional Estimates of Multiple Exotic Annual Grass (EAG) Species in the Sagebrush Biome, USA, 2016-2024 (ver. 5.0, July 2025)
This dataset provides annual (2016 - 2024) estimates of fractional cover for Exotic Annual Grass (EAG) species and a native perennial bunch grass for rangelands of the western United States. The dataset includes four (five for 2023 and 2024) fractional cover maps per year, accompanied by corresponding confidence maps, for a group of 15 EAG species. The following 15 species are included...
U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX U-Pb zircon data for: Upper Triassic and Jurassic sedimentary rocks from Sonora, MX
This laser ablation ICPMS U-Pb zircon data set supports stratigraphic, biostratigraphic and age interpretations of the of the fossil-plant-bearing El Game?o Formation of west-central Sonora, Mexico and the potentially age-correlative fossil-plant-bearing Santa Clara and Coyote formations of southeastern Sonora, Mexico. The zircon data provides minimum age constraints (maximum...
Microbiology of the Utica Shale Microbiology of the Utica Shale
In order to determine the innate microbial community of shale gas reservoirs and how they are impacted by hydraulic fracturing, this study analyzed biomass collected from produced water and rock from hydraulically fractured wells in the Utica Shale. The samples include rock chips from a drill core from one Utica well, produced water from that same Utica well, and produced water from 12...
Pre-rehabilitation Biological Assessment of the Lower Maumee River, Ohio, 2019 Pre-rehabilitation Biological Assessment of the Lower Maumee River, Ohio, 2019
Data are from biological and physical environmental assessments conducted during 2019 in the Maumee River, Ohio. Sites were located from river kilometer 24 to 11. Water quality parameters, fishes, invertebrates, and river channel characteristics were assessed during 2019 from May-September. Previously established standardized sampling methods were used during all assessments.
Amphibian Chytrid Swab Data from Churchill County, Nevada (2019-2021) Amphibian Chytrid Swab Data from Churchill County, Nevada (2019-2021)
This dataset includes results from external skin swabbing of Anaxyrus williamsi and Lithobates catesbeianus to test for the fungus Batrachochytrium dendrobatidis from the Dixie Valley in Churchill County, Nevada, in 2019-2021.
Data on Produced Water Quality and Quantities from Hydraulically Fractured Williston Basin Oil Wells Data on Produced Water Quality and Quantities from Hydraulically Fractured Williston Basin Oil Wells
This dataset contains compositional data on 17 produced water samples from hydraulically fractured unconventional oil wells completed in the Middle Bakken and Three Forks Formations. The oil wells are located in five different wellfields across the Williston Basin. Specific gravity, conductivity, temperature, pH and oxidation-reduction potential for each sample was measured in the field...
