This data release provides digital flight line data for a high-resolution airborne radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 34,041 line km of magnetic and radiometric data were acquired over an irregular-shaped area of 6178 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along E-W flight lines spaced at 200 m intervals. Tie lines were flown in an N-S...

This data release includes raw detrital zircon U-Pb data for isolated sandstones in Upper Triassic deposits of the Auld Lang Syne basin of northwest Nevada, USA. Detrital zircon U-Pb data for 11 sandstone samples (3269 zircon U-Pb dates) were acquired via LA-ICP-MS at the University of Arizona LaserChron Center for 11 sandstone samples. Primary insights from the data are twofold: 1) The data provide information about sediment provenance and indicate that sediment of the Auld Lang Syne basin was primarily derived from near the ancestral Ouachita orogen of Texas and Oklahoma. Sediment was transported to the Auld Lang Syne basin by a Late Triassic transcontinental river system, recorded today by the Upper Triassic...

The Cabin Branch and Cabin Creek (Cappy Avenue) outcrops are located along two small creeks in Prince George’s County, Maryland. The Cabin Branch outcrop contains exposures of silty sands of the Upper Cretaceous Severn Formation, and both outcrops contain Paleocene silty quartz and glauconitic sands of the Danian Brightseat Formation and highly fossiliferous glauconitic quartz sands of the Selandian Aquia Formation. Data from these two locations were generated in order to designate a Principal Reference Section for the Danian age Brightseat Formation. The Cabin Branch outcrop consists of disjunct exposures along an approximately 0.4-mile section of the creek. At the nearby Cabin Creek (Cappy Avenue) outcrop a more...
These data were compiled to evaluate impacts of different reservoir management scenarios on sand exposure for aeolian landscape and cultural site resources. Objective of our study was to predict areas of dry, bare Colorado River sand as a function of different management alternative scenarios. These data represent predictions of dry, bare sand for the reach of the Colorado River between Glen Canyon Dam and Bright Angel Creek in Grand Canyon National Park. These data were created during 2023 by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring and Research Center. These data can be used to understand how the area of sand available for windblown transport might be impacted different...
This data release consists of daily mean streamflow, daily mean suspended sediment concentration (SSC), and daily mean suspended sediment load (SSL) data for selected U.S. Geological Survey (USGS) streamgage sites within the Fountain Creek watershed, separated by water year. Each file also includes USGS approval levels and any associated qualifiers that were applied to the values. The daily mean SSC and daily mean SSL were calculated using the program, Graphical Constituent Loading Analysis System (GCLAS) , and are publicly available in the USGS National Water Information System (NWIS) database. Methods used in GCLAS to calculate daily mean SSC and SSL will not be discussed in this data release (see: User's manual...

These data were compiled for/to modeling to assess impact of management scenarios on Colorado River sediment resources. Objective(s) of our study were to assess impact of management scenarios on Colorado River sediment resources. These data represent model results for high flow experiment timing/duration, sand mass balance, sandbar volume, based on the data in the Interim Guidelines SEIS and LTEMP SEIS folders. These data were generated in 2023-2024 and are model simulations of Colorado River sediment resources downstream of Glen Canyon dam. These data were created by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring & Research Center with models generated and codes written/adapted...
These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in comma-delimited table format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri and Mississippi Rivers on the periphery of Missouri, June 13–22, 2021. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach. Data collection software integrated and stored the depth data from the MBES and the...
The Spor Mountain study area is located in the Spor Mountain Range, approximately 42 miles northwest of Delta, Utah. Mining in the Spor Mountain district began in the 1940s and continues to present day. Fluorspar, uranium, and beryllium are the main ores mined(Ege, 2005). From August through September 2013, the United States Geological Survey (USGS) collected a total of 73 samples from abandoned mine wastepiles, channel sediments downslope of wastepiles, and background areas. The samples were sieved to obtain the less than 177 micron fraction. Geochemical analyses were completed through a third-party contract by General Society of Surveillance (SGS) with method ICM40B - Fifty-five major (except Si and Na), rare...

From October 2017 to June 2018, the United States Geological Survey (USGS) collected 101 surficial sediment samples from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology in the Browns Park mining district of northeastern Utah. Additionally, twelve sediment samples were collected in drainages associated with legacy sample locations from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program (reformatted by Smith, 2006). The Browns Park district is in the eastern arch of the Uinta Mountain Range, north of the Green River, and approximately 5 miles west of the...

The data set describes the characterization of organosilica nanoparticle thin films used to adsorb PCBs from laboratory water and a sediment collected near Anniston Alabama. Data not shown here for the porewater and sediment PCB concentrations can be found in Appendix 1 of Ingersoll et al. 2014 (http://dx.doi.org/10.3133/sir20135125) Bulk sediment chemistry was obtained from Table A1-3a.Porewater estimated from solid phase microextraction fibers was obtained from Table A1-3c. The concentration of PCB in Lumbriculus variegatus was obtained from Table A1-3e.
