Enhanced Terrain Imagery of the Radford 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Radford 30 x 60 minute quadrangle in Virginia. It also covers a part of the Appalachian Basin Province. The source data used to construct this imagery consists of 1-meter resolution lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2018 an

2022 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York

This U.S. Geological Survey (USGS) data release provides surface water quality and groundwater elevation data collected by USGS personnel within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2021 through September 30, 2022. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a comprehensive water

Eggshell Thickness in 5 Songbird Species

Eggshell thickness was measured at the egg equator and sharp pole for 5 songbird species. Each egg has thickness measurements at two locations on the egg and the corresponding egg length, egg width, egg volume, relative incubation age, egg identification, and nest identification. These data support the following publication: Schacter, C.R., Peterson, S.H., Hartman, C.A., Herzog, M.P., and Ackerma

Multiple-Well Aquifer-Test Data and Results, Umatilla Indian Reservation near Mission, Northeastern Oregon, 2016

This data release presents tabular data used and analytical water-level modeling files generated as part of a U.S. Geological Survey study, done in cooperation with the Confederated Tribes of the Umatilla Indian Reservation, to evaluate water-level change from a multiple-well aquifer test in well 422 on the Umatilla Indian Reservation near Mission, Oregon. Water-level, pumping, and barometric-pres

Various Lake Powell data used for predicting smallmouth bass entrainment rates and population growth based on thermal suitability below and downstream of Glen Canyon Dam

These data were compiled to create models that estimate entrainment rates and population growth rates of smallmouth bass below Glen Canyon Dam. Objective(s) of our study were to predict smallmouth bass entrainment rates and population growth under different future scenarios of Lake Powell elevations and management. These data represent parameters needed for associated models and data needed to pro

Chirp sub-bottom data collected in Lake Crescent, Washington during USGS field activity 2019-622-FA

Chirp sub-botttom data were acquired during USGS field activity 2019-622-FA in August of 2019. The survey was conducted in Lake Crescent, Washington. Geophysical mapping was conducted to investigate earthquake triggered mass transport deposits as part of the Cascaadia Earthquake recurrence project. These data and information are intended for science researchers, students, policy makers, and the ge

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 hazards, which

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 distribution of annu

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 resistivity logs a

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 dry nodes th

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 important stratigr
