Argon data for HD-B1 intercalibration Argon data for HD-B1 intercalibration
This data release includes 40Ar/39Ar intercalibration data from the U.S. Geological Survey for neutron fluence monitors HD-B1 (Heidelberg biotite) and FCs (Fish Canyon sanidine). Potassium-bearing mineral grains were analyzed by argon geochronology at the U.S. Geological Survey Argon Geochronology Laboratory in Denver, Colorado. These data provide intercalibration information between the...
Velocity and Bathymetric Data near Outlet Structures for the City of Omaha Water Resource Recovery Facilities on the Missouri River, 2020 Velocity and Bathymetric Data near Outlet Structures for the City of Omaha Water Resource Recovery Facilities on the Missouri River, 2020
These data sets were derived from surveys at the Missouri River and Papillion Creek Water Resource Recovery Facility outfalls on the Missouri River. Each site had three transects, one at the outfall, one 45.7 meters upstream of the outfall and one 45.7 meters downstream of the outfall. Velocity and depth data were collected using an acoustic Doppler current profiler at each transect...
Seepage-run discharge measurements, September 8, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i Seepage-run discharge measurements, September 8, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i
This data release contains a comma-delimited ascii file of nine discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on September 8, 2021. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow...
Geochemical data for the Elk Creek alkaline complex, southeast Nebraska Geochemical data for the Elk Creek alkaline complex, southeast Nebraska
This U.S. Geological Survey (USGS) data release contains analytical data from a suite of rock and mineral samples collected from drill core within the Elk Creek alkaline complex, southeast Nebraska. This complex hosts the Elk Creek carbonatite, a multilithologic carbonatite enriched in niobium, rare earth elements (REEs), scandium, and titanium. Mineralized carbonatites are the world's
River-channel topography, grain size, and turbidity records from the Carmel River, California, before, during, and after removal of San Clemente Dam (ver. 2.0, March 2022) River-channel topography, grain size, and turbidity records from the Carmel River, California, before, during, and after removal of San Clemente Dam (ver. 2.0, March 2022)
The San Clemente Dam, built in the 1920s on the Carmel River in Monterey County, California, was removed during 2014 and 2015. The dam-removal project was the largest in California to date, and one of the largest in the U.S. This USGS data release presents data collected before, during, and after the removal of the dam. The data were collected to study how the river channel's topographic...
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) geochemical data for apatite grains in rocks and stream sediments from the Taurus porphyry copper deposit area, eastern Tanacross quadrangle, Alaska Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) geochemical data for apatite grains in rocks and stream sediments from the Taurus porphyry copper deposit area, eastern Tanacross quadrangle, Alaska
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses of apatite provide trace element concentrations that support indicator mineral studies near the Taurus porphyry Cu-Mo deposit in the eastern Tanacross quadrangle, Alaska. The Taurus deposit and others in the region are mostly concealed, and traditional stream sediment samples typically show subdued...
