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. 2.0, April 2025) 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. 2.0, April 2025)
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...
