Phytoplankton Community Composition in Western Lake Erie, 2014-2018; Grand Traverse Bay, Lake Michigan, 2015; and Saginaw Bay, Lake Huron, 2015 Phytoplankton Community Composition in Western Lake Erie, 2014-2018; Grand Traverse Bay, Lake Michigan, 2015; and Saginaw Bay, Lake Huron, 2015
This dataset contains a tabular file of phytoplankton abundance and community composition analysis in samples collected from eight sites in the Western Lake Erie Basin; four sites in Grand Traverse Bay, Lake Michigan; and five sites in Saginaw Bay, Lake Huron. Samples were collected and processed by the Great Lakes Science Center of the U.S. Geological Survey (USGS) and analyzed by BSA
Map data from landslides triggered by Hurricane Maria in the greater karst region of northwest Puerto Rico Map data from landslides triggered by Hurricane Maria in the greater karst region of northwest Puerto Rico
Hurricane Maria caused widespread landsliding throughout Puerto Rico in September 2017. While the majority of landslide inventories following the hurricane focused on mountainous regions underlain by igneous and volcaniclastic bedrock (Bessette-Kirton et al., 2017, 2019), here we fill an important knowledge gap and document the occurrence of landslides along the greater karst region on...
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...
High-resolution maps of projected big sagebrush plant community biomass for 52 future climate scenarios using multivariate matching algorithms High-resolution maps of projected big sagebrush plant community biomass for 52 future climate scenarios using multivariate matching algorithms
These data were compiled for the study: Divergent climate change effects on widespread dryland plant communities driven by climatic and ecohydrological gradients. The objectives of our study were to (1) describe how climate change will alter the biomass and composition of key plant functional types; (2) quantify the impacts of climate change on future functional type biomass and...
High-resolution maps of historical and 21st century ecological drought metrics using multivariate matching algorithms for drylands of western U.S. and Canada High-resolution maps of historical and 21st century ecological drought metrics using multivariate matching algorithms for drylands of western U.S. and Canada
These data were compiled using a new multivariate matching algorithm that transfers simulated soil moisture conditions (Bradford et al. 2020) from an original 10-km resolution to a 30-arcsec spatial resolution. Also, these data are a supplement to a previously published journal article (Bradford et al., 2020) and USGS data release (Bradford and Schlaepfer, 2020). The objectives of our...
Location Data for Petrographic Samples and Isotopic and Age Data from Detrital Zircon Grains from Selected Rock Samples from St. Lawrence Island and the Western Brooks Range, Alaska Location Data for Petrographic Samples and Isotopic and Age Data from Detrital Zircon Grains from Selected Rock Samples from St. Lawrence Island and the Western Brooks Range, Alaska
This dataset contains a list of geologic station localities on St. Lawrence Island, Alaska, from which thin section samples were examined. The dataset also contains U-Pb isotopic data and ages of detrital zircon (DZ) from sedimentary rocks collected on St. Lawrence Island and in the western Brooks Range. All St. Lawrence Island samples (DZ and thin sections) were collected by U.S...
Data Used to Assess the Acute Physiological Response of Polar Bears to Helicopter Capture Data Used to Assess the Acute Physiological Response of Polar Bears to Helicopter Capture
This dataset is in five tables with data from ecophysiological studies of free-ranging polar bears of the Southern Beaufort Sea subpopulation. They were equipped with high-resolution activity sensors, body temperature loggers, and GPS satellite-telemetry collars, to compare physiological state and activity of bears during natural behavior with that experienced by bears during helicopter...
