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 (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...
MODFLOW 6 model and ensemble used in the simulation of groundwater flow and land subsidence in the northern part of the Gulf Coast aquifer, 1897-2018 (ver. 2.0, September 2023) MODFLOW 6 model and ensemble used in the simulation of groundwater flow and land subsidence in the northern part of the Gulf Coast aquifer, 1897-2018 (ver. 2.0, September 2023)
The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter...
Ken Pierce's Legacy Field Notebooks and Annotated Aerial Photographs, Geological, and Topographical Maps from Across the Western United States 1963-2021 (ver. 2.0, January 2024) Ken Pierce's Legacy Field Notebooks and Annotated Aerial Photographs, Geological, and Topographical Maps from Across the Western United States 1963-2021 (ver. 2.0, January 2024)
Ken Pierce was a Research Geologist with the U.S. Geological Survey for over 55 years and authored numerous scientific papers, geologic maps, and field trip guides. This data release contains digital scans of 44 field notebooks authored by Ken Pierce or his collaborators. Information contained in these notebooks provided much of the underpinning of Ken Pierce's research on the glacial...
Argon and SHRIMP-RG Data for Magmatic Steam Alunite, Sericite, and Zircon from Alunite Ridge and Deer Trail Mountain, Marysvale, Utah Argon and SHRIMP-RG Data for Magmatic Steam Alunite, Sericite, and Zircon from Alunite Ridge and Deer Trail Mountain, Marysvale, Utah
Samples of vein-type magmatic-steam alunite were collected over several field seasons from five mines and prospects (L&N, Mt. Edna, Christmas, upper Mineral Products, and Close In) in the Alunite Ridge and Deer Trail Mountain area, Marysvale, Utah, as well as a sample from the Deer Trail mine workings from which sericite was separated. The magmatic-steam alunite and sericite were...
Plant cover, climate, grazing disturbance, and soil class data from 1991-2020 compiled from remotely sensed data on two retired grazing allotments in Capitol Reef National Park, Utah, USA Plant cover, climate, grazing disturbance, and soil class data from 1991-2020 compiled from remotely sensed data on two retired grazing allotments in Capitol Reef National Park, Utah, USA
These data were compiled for use by researchers and land managers in studies of post-grazing change in Capitol Reef National Park. The data were initially used for and are associated with the McNellis et al., 2023 (see Larger Work Citation). Objective(s) of our study were to study landscape change (specifically plant cover measured through remote sensing) through time in Capitol Reef...
Meteorological measurements from five weather stations in Grand and San Juan Counties in southeastern Utah (ver. 3.0, September 2024) Meteorological measurements from five weather stations in Grand and San Juan Counties in southeastern Utah (ver. 3.0, September 2024)
These data were compiled from six automated weather stations that together provide several points in the meteorological record across a latitudinal and elevational gradient in southeastern Utah. Recorded data from these weather stations are associated with several different studies. Meteorological data are important for quantifying short term weather events as well as longer term climate...
Host vs. Pathogen Evolutionary Arms Race: Effects of Exposure History on Individual Response to a Genetically Diverse Pathogen Host vs. Pathogen Evolutionary Arms Race: Effects of Exposure History on Individual Response to a Genetically Diverse Pathogen
This data set contains individual adult bighorn sheep entry and exit/censor times for 3 disease states and 2 mortality states: susceptible, infected and recovered and disease-caused death and non-disease related death. These times are used in a time-to-event analysis that employs a mixture model approach to characterize transition rates between states.
