Regional invasive annual grass simulation models and invaded cover across the sagebrush biome (2022-2042) Regional invasive annual grass simulation models and invaded cover across the sagebrush biome (2022-2042)
This data release contains spatially explicit state-and-transition simulation model (STSM) packages, simulation results, and projected invaded cover layers of Invasive annual grasses (IAG). IAGs continue to spread within the sagebrush biome of the western United States, and managers need ways to scope IAG management strategy effectiveness for long-term strategic planning. We developed a...
Data from petrological and geochemical analyses of fast pyrolysis bio-oil distillation residues and naturally formed solid fossil fuels Data from petrological and geochemical analyses of fast pyrolysis bio-oil distillation residues and naturally formed solid fossil fuels
Distillation of fast pyrolysis bio-oils leaves solid residues analogous to those from distillation of fossil fuels or from natural subsurface petroleum formation (i.e., solid bitumen) or other natural carbon concentration processes (e.g., coal formation). Much like petroleum-based residues, bio-oil residues vary in terms of quality, yield, and versatility for downstream applications. For...
Density and magnetic susceptibility measurements on Archean and Proterozoic rocks, southern Medicine Bow Mountains, Wyoming, 2021-2024 Density and magnetic susceptibility measurements on Archean and Proterozoic rocks, southern Medicine Bow Mountains, Wyoming, 2021-2024
Rock physical property measurements were collected on outcrops to help understand the causative sources of gravity and magnetic survey anomalies in the southern Medicine Bow Mountains of Wyoming. A total of 539 magnetic susceptibility measurements and 318 density measurements have been conducted. The resulting data aid in interpretation of gravity and airborne magnetic data that are...
Mercury, methylmercury, and related geochemical data from incubations of materials flocculated in mesocosms within the Cache Creek Settling Basin, California Mercury, methylmercury, and related geochemical data from incubations of materials flocculated in mesocosms within the Cache Creek Settling Basin, California
The U.S Geological Survey (USGS) is assessing the potential for in-situ addition of metal-based coagulants to enhance mercury (Hg) capture in the Cache Creek Settling Basin (CCSB), a wetland-like environment designed to trap mercury-contaminated sediments from upstream historical mining activities in the Cache Creek watershed. Laboratory and field tests by the USGS show that three tested
Crosswalk of Waterbody Identifiers between National Hydrography Dataset Plus High Resolution, National Hydrography Dataset Plus V2, and Hydrolakes datasets for the Contiguous United States Crosswalk of Waterbody Identifiers between National Hydrography Dataset Plus High Resolution, National Hydrography Dataset Plus V2, and Hydrolakes datasets for the Contiguous United States
Overview: There are multiple systems for mapping waterbodies within the conterminous United States. Prominent among them are the "High Resolution" and "Version 2" editions of the National Hydrography Dataset Plus. The National Hydrography Dataset Plus High Resolution (NHDPlusHR, Moore and others, 2025) uses "Permanent Identifiers" to identify waterbodies, while the National Hydrography...
Repeat photos from long-term monitoring plots of biological soil crusts in an ungrazed grassland of southeastern Utah Repeat photos from long-term monitoring plots of biological soil crusts in an ungrazed grassland of southeastern Utah
This data release contains a timeseries (2004-2025) of photographs from five permanent locations (Stops 1-5, roughly 11x15 centimeters) established to observe biological soil crusts (BSC, a collection of species of lichens, cyanobacteria, and bryophytes). The five locations were randomly located within a larger study area established to monitor vegetation and biological soil crusts as...
