Whole Rock Geochemistry and Uranium Lead Isotopic Data from the Dinwiddie Terrane, Virginia, USA Whole Rock Geochemistry and Uranium Lead Isotopic Data from the Dinwiddie Terrane, Virginia, USA
This data release includes whole rock geochemical data, and uranium-lead isotopic data collected by both Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods. Whole rock geochemistry was collected by Activation Laboratories in Ancaster, Ontario. LA-ICP-MS data was collected at the PLASMA...
Model Archive Data for Suspended-Sediment Regression at Station 07355860, Board Camp Creek near Wolf Pen Gap Recreation Area near Nunley, AR Model Archive Data for Suspended-Sediment Regression at Station 07355860, Board Camp Creek near Wolf Pen Gap Recreation Area near Nunley, AR
Data from an optical turbidity sensor deployed at the stream station were recorded at 15-minute intervals by a data logger and uploaded every hour to the U.S. Geological Survey (USGS) database (Anderson, 2005; Wagner, 2006). Suspended-sediment samples were collected using a suction pump autosampler, equal width increments, or grab sampling techniques (Edwards, 1999). The use of an...
Trace element data in whole blood collected in 2001 from Steller's eiders at Izembek Lagoon and Steller's eiders, harlequin ducks, black scoters, and a long-tailed duck at Dutch Harbor, Alaska Trace element data in whole blood collected in 2001 from Steller's eiders at Izembek Lagoon and Steller's eiders, harlequin ducks, black scoters, and a long-tailed duck at Dutch Harbor, Alaska
Trace element data in whole blood collected in 2001 from Steller's eiders (Polysticta stelleri; STEI) at Izembek Lagoon and Steller's eiders, harlequin ducks (Histrionicus histrionicus; HADU), black scoters (Melanitta americana; BLSC), and a long-tailed duck (Clangula hyemalis; LTDU) at Dutch Harbor, Alaska. Data include species, location, age, sex, percent moisture of blood sample, and...
Grass Carp detections via stationary receivers and manual tracking on Truman Reservoir, MO, January 2017 to October 2019 Grass Carp detections via stationary receivers and manual tracking on Truman Reservoir, MO, January 2017 to October 2019
Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from January 2017 to October 2019 to determine longitudinal movements potentially associated with spawning. Passive acoustic receivers were deployed throughout the reservoir and its tributaries to monitor fish movements as they traversed up and...
Depth to Groundwater Measured from Wells Completed in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston Area, Texas, 2021 Depth to Groundwater Measured from Wells Completed in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston Area, Texas, 2021
This dataset documents the depth to groundwater measured in wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining system, or a combination of multiple hydrogeologic units in the greater Houston area, Texas for 2021. The U.S. Geological Survey prepared this dataset in cooperation with the Harris?Galveston Subsidence...
Aeromagnetic Data and horizontal gradient maxima of Blythe, California, and Surrounding Areas in California and Arizona Aeromagnetic Data and horizontal gradient maxima of Blythe, California, and Surrounding Areas in California and Arizona
This data release provides access to an aeromagnetic survey and magnetization boundaries over Blythe, California and surrounding areas in southern California and western Arizona. The survey extends east of Joshua Tree National Park across the Colorado River and west over the Dome Rock, Trigo, and Plomosa Mountains in Arizona. The survey was flown north of the Chocolate Mountains Gunnery...
