Data

For use as part of a regional petroleum assessment, the USGS in the early 1990's developed a dataset reporting elevation on the surface of the Precambrian basement of the central and southern Colorado Plateau and vicinity (Butler, 1991). This dataset was released as paper report that included a table of basement elevations at more than 3,700 control points, including outcrop data of...

As part of the Coastal Sediment Availability and Flux Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey to map the shoreface of Cedar Island, Virginia (VA) in August of 2019. The objective of the project is to improve the understanding of barrier island geomorphic evolution and the sediment...

Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Port Westward site - USGS site ID# 14246900. The time series suspended sediment data will help determine the suspended sediment concentration at the site...

This data release contains programmed pyrolysis, organic petrographic (reflectance), and semiquantitative X-ray diffraction mineralogy data for subsurface coal and shale samples from around the world. Samples were subjected to hydrous or anhydrous pyrolysis experiments at varying temperatures and the resulting residues were analyzed via programmed pyrolysis and reflectance to document...

These raster images represent continuous surfaces of estimated land cover types for the western Kenai Peninsula circa 1973, circa 2002, and circa 2017. The estimated land cover types (Needleleaf Forest, Mixed Forest, Broadleaf Forest, Herbaceous, Wetland, Alpine, Barren, Shrub, Water) were derived from a random forest classifier executed in R (version 3.5.0). Predictor variables from...

The one-dimensional model inputs of idealized topography and bathymetry values for simulation of synthetic storm evolution with XBeach, as described in Mickey and others (2020) are provided here. The idealized topography and bathymetry were derived from LiDAR data from Dauphin Island, AL, USA over the timespan of 2005 to 2015. For further information regarding model input generation of...

This report documents river response to hydrologic disturbance along a 140-km segment of the mainstem Klamath River below Iron Gate Dam, CA by assessing fundamental indicators of active sediment transport and dynamic changes in riparian vegetation. A combination of field and remote sensing methods were used to document river response to natural rainfall-runoff events (e.g., 2006 and 2017...

This dataset contains the capture location and summer location of deer radio-collared in the Garden Lake deeryard, near Ely MN during the summers of 1998, 1999, 2001, 2014, and 2017. The data set also contains the distance and direction deer migrated from capture locations to summer locations.

Data include burrowing behavior of juvenile freshwater mussels (Lampsilis siliquoidea); Villosa constricta; Megalonaias nervosa; Villosa iris; Lampsilis powellii; and Anodonta oregonensis) in three types of sediment [a sand/silt/clay mixture (49 percent sand) with a total organic carbon (TOC) content of about 3 percent obtained from northeastern Minnesota, a predominantly fine sand (82...

Input predictor variables and output predictions from statistical modeling of floodplains, streambanks, and streambeds for each NHDPlusV2 stream reach in the Chesapeake Bay and Delaware River watersheds of the U.S. Mid-Atlantic. Random Forest statistical models using either 1) characteristics of upstream drainage area, or 2) characteristics of upstream drainage area (Wieczorek et al...

Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...

A Soil-Water Balance (SWB) model of the alluvial aquifer in north Summerset, South Dakota, was constructed to estimate recharge and potential evapotranspiration volumes and rates for 2017-19. The model area included the northern part of the city of Summerset in west South Dakota along the east range of the Black Hills. The model area was defined as a rectangular area that included the...
