2020 winter timeseries of UAS derived digital surface models (DSMs) from the Hourglass study site, Bridger Mountains, Montana, USA 2020 winter timeseries of UAS derived digital surface models (DSMs) from the Hourglass study site, Bridger Mountains, Montana, USA
Unmanned Aerial System (UAS) flights were conducted over the headwaters of the South Fork of Brackett Creek in the Bridger Mountains of SW Montana during the winter of 2020. The flights collected overlapping imagery focused on a steep mountain couloir study site known locally as "the Hourglass." Structure from motion (SfM) photogrammetry was used to process the collected imagery and...
Biological and chemical data from attenuated and pulsed exposures of fire chemical to fish Biological and chemical data from attenuated and pulsed exposures of fire chemical to fish
Survival endpoints for juvenile rainbow trout (Oncorhynchus mykiss) and fathead minnows (Pimephales promelas) in response to exposure to wildland firefighting chemicals. Exposures were either attenuated or pulsed. For attenuated exposures, chemical treatment was applied at the beginning of the exposure and control water was added for the duration of the assay so chemical concentration...
Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the United States (ver. 10.0, May 2023) Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the United States (ver. 10.0, May 2023)
Version 10.0 of these data are part of a larger U.S. Geological Survey (USGS) project to develop an updated geospatial database of mines, mineral deposits, and mineral regions in the United States. Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as 'mine' symbols or features, have been digitized...
Absorbance and Fluorescence Excitation-Emission Matrix Data for Produced Waters from Oil and Gas Producing Basins in the United States Absorbance and Fluorescence Excitation-Emission Matrix Data for Produced Waters from Oil and Gas Producing Basins in the United States
Waters co-produced during petroleum extraction are normally considered wastes but are also possible resources, especially in water-stressed regions. Produced waters can be chemically complex. High salinity, naturally occurring radioactive materials, and organic substances derived from the producing formation can complicate treatment processes. Rapid screening methods to characterize...
Historical and future ecological drought conditions for rangelands of the western U.S. Historical and future ecological drought conditions for rangelands of the western U.S.
These NetCDF data were compiled to investigate how rangelands in the western U.S. are limited by access to water. As a result, these ecosystems may be especially vulnerable to changes in water availability and drought as a result of climate change. This project utilized an ecosystem water balance model to quantify spatial and temporal patterns of rangeland ecological drought conditions...
High-resolution maps of historical and 21st century soil temperature and moisture data using multivariate matching algorithms for drylands of western U.S. and Canada High-resolution maps of historical and 21st century soil temperature and moisture data using multivariate matching algorithms for drylands of western U.S. and Canada
These data were compiled as a supplement to a previously published journal article (Bradford et al., 2019), that employed a ecosystem water balance model to characterize current and future patterns in soil temperature and moisture conditions in dryland areas of western North America. Also, these data are associated with a published USGS data release (Bradford and Schlaepfer, 2019). The...
