Morphological and genetic data for Phragmites australis along the Colorado River and in tributaries from southern Utah to west-central Arizona Morphological and genetic data for Phragmites australis along the Colorado River and in tributaries from southern Utah to west-central Arizona
These data were compiled to provide land-management relevant information on the native and nonnative subspecies (subsp.) of Phragmites australis (subsp. americanus and subsp. australis, respectively) in Glen Canyon National Recreation Area (NRA), Grand Canyon National Park (NP), Arches National Park, and Bill Williams National Wildlife Refuge. Specifically, the goals of this work were to...
Channel and floodplain cross-section and bed-elevation data for the Green River in Echo, Island, and Rainbow Parks, Dinosaur National Monument, Colorado and Utah Channel and floodplain cross-section and bed-elevation data for the Green River in Echo, Island, and Rainbow Parks, Dinosaur National Monument, Colorado and Utah
These data were compiled to determine the rate and magnitude of channel-planform change, and the topographic change of the channel and floodplain in Echo, Island, and Rainbow Parks within Dinosaur National Monument between the 1990s and 2019. The objective(s) of our study were to analyze geomorphic change within Echo, Island, and Rainbow Parks to determine the magnitude and style of...
An Open Repository of U.S. Cone Penetration Test (CPT) data An Open Repository of U.S. Cone Penetration Test (CPT) data
Cone Penetration Test (CPT) data collected by the U.S. Geological Survey since 1978 are compiled and provided as a uniformly formatted set of comma separated value (.csv) files. This dataset includes 1822 CPT soundings from 14 U.S. States. Provided CPT data are a set of three column comma separated value (.csv) files containing depth (meters), tip resistance (̨MPa), and sleeve resistance...
Emergence and growth of four native Intermountain West perennial grasses under six water availability regimes Emergence and growth of four native Intermountain West perennial grasses under six water availability regimes
These data were compiled to evaluate the effects of seed coat treatments on the emergence and growth of four native Intermountain West perennial grasses exposed to six different water availability regimes. The objective of our study was to evaluate how seed coat treatments influence seed response and seedling performance for different species exposed to different regimes of water...
Airborne magnetic and radiometric survey of the Boulder Batholith region, Montana, Butte extension 2023 Airborne magnetic and radiometric survey of the Boulder Batholith region, Montana, Butte extension 2023
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 45...
Annual variation in summer phytoplankton communities influenced by river morphology and seasonal environmental conditions Annual variation in summer phytoplankton communities influenced by river morphology and seasonal environmental conditions
Phytoplankton samples were collected from the La Grange reach of the Illinois River from 2010-2020. Samples were collected from main channel, side channel and backwater areas. The following dataset includes phytoplankton community data (e.g., taxa, biovolume, cell counts, etc.). Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by...
