National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to 2010s for the coast of California National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to 2010s for the coast of California
In coastal areas of the United States, where water and land interface in complex and dynamic ways, it is common to find concentrated residential and commercial development. These coastal areas often contain various landholdings managed by Federal, State, and local municipal authorities for public recreation and conservation. These areas are frequently subjected to a range of natural...
Peak Streamflow Data, Climate Data, and Results from Investigating Hydroclimatic Trends and Climate Change Effects on Peak Streamflow in the Central United States, 1921–2020 Peak Streamflow Data, Climate Data, and Results from Investigating Hydroclimatic Trends and Climate Change Effects on Peak Streamflow in the Central United States, 1921–2020
Peak-flow frequency analysis is crucial in various water-resources management applications, including floodplain management and critical structure design. Federal guidelines for peak-flow frequency analyses, provided in Bulletin 17C, assume that the statistical properties of the hydrologic processes driving variability in peak flows do not change over time and so the frequency...
Delta log R total organic carbon estimates for the Tuscaloosa marine shale, U.S.A. Delta log R total organic carbon estimates for the Tuscaloosa marine shale, U.S.A.
This dataset contains estimated total organic carbon (TOC) calculated using the delta log R (dlogR) method, developed by Passey and others (1990), within BasinMod modeling software for the Tuscaloosa marine shale (TMS) in southwestern Mississippi, U.S.A. BasinMod is a modeling software developed by Platte River Associates, Inc. Using version 2021-03-03 of the software, sonic and...

Data includes functional group cover of annual grasses, perennial grasses and shrubs, and model predicted fire behavior for the years of 2018-2021.
MODFLOW-NWT models and calibration files for the Mississippi Alluvial Plain, USA MODFLOW-NWT models and calibration files for the Mississippi Alluvial Plain, USA
The existing three-dimensional groundwater flow model (MODFLOW-2005) of the Mississippi Embayment Regional Aquifer system (MERAS), South-Central United States, was updated with: 1) higher stream density; 2) more spatially refined recharge; 3) better estimates of water use; 4) more recent time period simulated; 5) more realistic storage conceptualization; and 6) more robust handling of...
Electron microprobe geochemical data for glass from the Khonkho tephra Electron microprobe geochemical data for glass from the Khonkho tephra
These data are presented to geochemically characterize glass from the informally named Khonkho tephra, an ashfall deposit that crops out at the Khonkho Wankane archaeological site in Jesus de Machaca, Bolivia. The Khonkho tephra appears to have been emplaced by a major explosive eruption from a currently unknown volcanic source. The unit forms a marker bed at an archaeologically...
Chemistry data from leachates of hydraulic fracturing proppants collected from southeastern New Mexico, 2018-2019 Chemistry data from leachates of hydraulic fracturing proppants collected from southeastern New Mexico, 2018-2019
Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the...
Helicopter-based videos and orthomosaic maps produced for Integrated Water Science basin riverine study sites, 2022 Helicopter-based videos and orthomosaic maps produced for Integrated Water Science basin riverine study sites, 2022
A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Integrated Water Science basin riverine study sites in 2022. Videos were collected using both natural color and thermal infrared cameras. These videos were used to determine the feasibility of estimating river surface velocity using aerial imagery. Orthomosaic maps were produced from the natural...
Serologic Survey of Selected Arthropod Borne Pathogens in Free-ranging Snowshoe Hares (Lepus americanus) Captured in Northern Michigan, USA Serologic Survey of Selected Arthropod Borne Pathogens in Free-ranging Snowshoe Hares (Lepus americanus) Captured in Northern Michigan, USA
We conducted a serosurvey of snowshoe hares (Lepus americanus) for vector-borne pathogens in 2016-2017 that were captured in the Hiawatha National Forest in the eastern Upper Peninsula of Michigan, USA. At capture, in addition to age, sex, body weight of the hare and a blood sample data was collected on the ecological land type (USDA Forest Service. 2006. Hiawatha National Forest 2006...
Data from temperature measurements in research drill hole Y-7, Upper Geyser Basin, Yellowstone National Park Data from temperature measurements in research drill hole Y-7, Upper Geyser Basin, Yellowstone National Park
Active thermal areas in Yellowstone National Park provide insight into a variety of hydrothermal processes occurring at depth, such as water-rock interactions, the formation of alteration minerals, and microbial (thermophile) metabolism in extreme environments. Research drill hole Y-7 (44°29'8.74", -110°51'7.67") is one of 13 holes completed by the U.S. Geological Survey in 1967 and 1968...
