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...
Great Lakes seamless topobathymetric digital elevation models and shaded relief maps Great Lakes seamless topobathymetric digital elevation models and shaded relief maps
Modifications were made to existing great lakes topobathy data sets to interpolate areas of missing near shore elevation data. Areas with missing elevation data were not interpolated where there was low confidence in the underlying depth. This included rivers, canals, harbors, lakes, reservoirs, etc. Areas important for targeting Phragmites australis management often lie within these...
Anesthetic properties of carbon dioxide on native and invasive fishes Anesthetic properties of carbon dioxide on native and invasive fishes
This study evaluated the anesthetic properties of dissolved carbon dioxide on six fish species to determine its efficacy for use in sedating wild caught fish for surgeries. Phase I of this study aimed to inform induction time, recovery time, and short-term survival of fish using five different concentrations of carbon dioxide at one water temperature. Phase II determined the induction...
