Data

Borehole geophysical logs were collected to characterize bedrock aquifers at three contamination sites located in California, Wisconsin, and New Jersey. The data were collected by the U.S. Geological Survey (USGS) and the University of Guelph from 2014 to 2015 as part of the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental...

Neonicotinoids, a widely used class of insecticide, have been found in surface waters globally. They pose a risk to non-target species found in aquatic environments such as aquatic macroinvertebrates. To better understand the effects of the neonicotinoids imidacloprid, clothianidin and their mixtures on aquatic communities we ran a 30 day mesocosm test. Rock trays were colonized with...

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...

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...

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...

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.
