Stable isotope data for sulfur, oxygen, and hydrogen in minerals and gases and electron microprobe data for minerals from Sulphur Bank mercury mine, Lake County, California Stable isotope data for sulfur, oxygen, and hydrogen in minerals and gases and electron microprobe data for minerals from Sulphur Bank mercury mine, Lake County, California
Stable isotope compositions (the ratios deuterium/hydrogen, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) are reported for alunite, jarosite, kaolinite, silica, cinnabar, marcasite, and native sulfur from outcrops in and around the workings of the Sulphur Bank mercury mine, Lake County, California, and chemical compositions are reported, from electron microprobe analyses, for alunite and
Comparisons of dissolved-oxygen calibration methods at various elevations, Oregon, 2023 Comparisons of dissolved-oxygen calibration methods at various elevations, Oregon, 2023
Two dissolved-oxygen experiments were completed using internally logging water-quality monitors. Dissolved-oxygen sensors on the water-quality monitors were calibrated using various settings and at various elevations in Oregon, USA. Data from these experiments can be used 1) to assess how elevation affects dissolved-oxygen values recorded by continuous water-quality monitors, and 2) to
Alaska Resource Data File (ARDF) Alaska Resource Data File (ARDF)
The Alaska Resource Data File (ARDF) is a database of mines, prospects, and mineral occurrences in Alaska. It contains information compiled from published and unpublished sources from industry, U.S. Bureau of Mines (BOM), U.S. Geological Survey (USGS), and other government and private sources. ARDF is not a mining claims database.
Scanning electron microscopy data from sediments collected in ephemeral channels, Four Corners region, USA, 2021-2022 Scanning electron microscopy data from sediments collected in ephemeral channels, Four Corners region, USA, 2021-2022
The San Juan River is a major water source for communities in the Four Corners region of the United States (parts of Colorado, Arizona, New Mexico, Utah) and is a vital source of water for the Navajo Nation. The Navajo Nation Environmental Protection Agency (NNEPA) periodically samples surface water on the Navajo Nation and has found that some elements exceed NNEPA surface water...
Island of Hawaiʻi lidar-based habitat suitability for ʻākohekohe (Palmeria dolei) conservation introductions, 2023 Island of Hawaiʻi lidar-based habitat suitability for ʻākohekohe (Palmeria dolei) conservation introductions, 2023
This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat...
