Laser-ablation inductively-coupled-plasma mass spectrometry and electron probe microanalyses of pyrite and pyrrhotite in tailings and ores from volcanogenic massive sulfide and sedimentary-exhalative deposits Laser-ablation inductively-coupled-plasma mass spectrometry and electron probe microanalyses of pyrite and pyrrhotite in tailings and ores from volcanogenic massive sulfide and sedimentary-exhalative deposits
Mine waste, including mill tailings, could host substantial critical mineral resources. Developing an understanding of the mineral hosts and occurrence of critical minerals in mine waste is essential to evaluating their resource potential. Volcanogenic massive sulfide (VMS) and sedimentary-exhalative (SEDEX) deposits are important global sources of copper, zinc, lead, gold, and silver...
Elemental and biological characteristics of riparian spiders collected along streams and tributaries in the Clark Fork Basin, Montana, July 2023 (ver. 1.1, March 2026) Elemental and biological characteristics of riparian spiders collected along streams and tributaries in the Clark Fork Basin, Montana, July 2023 (ver. 1.1, March 2026)
This data release includes laboratory analyses for spider tissue samples collected from 20 sites in riparian areas along streams in the upper Clark Fork Basin in western Montana during July 2023. Samples were collected by the U.S. Geological Survey (USGS) in cooperation with the University of Connecticut. Analyses include 56 elements, percent moisture, and nitrogen and carbon isotopes in...
Genomic data from reduced representation DNA sequencing libraries of two partially fossorial salamanders Plethodon jordani and Desmognathus wrighti from Great Smoky Mountains National Park Genomic data from reduced representation DNA sequencing libraries of two partially fossorial salamanders Plethodon jordani and Desmognathus wrighti from Great Smoky Mountains National Park
This dataset contains sample information about the origin of the Desmognathus wrighti and Plethodon jordani salamanders collected from Great Smoky Mountains National Park and sequenced, and their corresponding SNP genotype data. These data were used to examine patterns of genomic structure of these two salamander species within Great Smoky Mountains National Park. The raw sequence data...

Movement Metrics of Adult Female Grizzly Bears and Polar Bears Used to Identify Cub Presence with Machine Learning Movement Metrics of Adult Female Grizzly Bears and Polar Bears Used to Identify Cub Presence with Machine Learning
These data represent movement metrics of adult female grizzly bears and polar bears with and without cubs-of-the-year at seven temporal scales after den departure. Grizzly bear data were collected in the Greater Yellowstone Ecosystem during 2000–2021 and in the Northern Continental Divide Ecosystem during 2003–2022. Polar bear data were collected in the Southern Beaufort Sea during 1986...
