Hydrodynamic and sediment transport data from two salt marshes and adjacent shallows in Northern San Francisco Bay, California 2022-2023 Hydrodynamic and sediment transport data from two salt marshes and adjacent shallows in Northern San Francisco Bay, California 2022-2023
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow subtidal and intertidal sites in Corte Madera Bay and San Pablo Bay National Wildlife Refuge (SPNWF) in San Francisco Bay, CA, as well as on the marsh plain of SPNWF marsh and in a tidal creek and on the marsh plain of Corte Madera Marsh, in 2022 and 2023...
Digital Shoreline Analysis System (version 6) Digital Shoreline Analysis System (version 6)
The Digital Shoreline Analysis System (version 6) is a stand-alone desktop application that complements a Geographic Information System (GIS). The DSAS software requires users to input a reference baseline and compilation of shoreline positions to generate measurement transects and shoreline intersections used to calculate rate-of-change statistics. DSAS provides an automated method for
Monthly normalized scaled surface wind friction velocity in the Uinta-Piceance Basin (UT, CO) for March to October from 2001 to 2016 Monthly normalized scaled surface wind friction velocity in the Uinta-Piceance Basin (UT, CO) for March to October from 2001 to 2016
These data were compiled to conduct a study on the effect of oil and gas development on dust emission potential in the Upper Colorado River Basin. The objectives of the study were to 1) assess the effect of oil and gas development on surface roughness, and 2) model the resultant effect of oil and gas development on sediment mass flux for a range of 10-m wind speeds and threshold wind...
Geomorphic basemap for the Colorado River in Grand Canyon, Arizona - May 2009 Geomorphic basemap for the Colorado River in Grand Canyon, Arizona - May 2009
These spatial data represent alluvial deposits of the Colorado River and tributary deposits adjacent to the Colorado River in Grand Canyon National Park. The map covers the river corridor from Lees Ferry, Arizona to the confluence with Diamond Creek 225 miles (362 km) downstream. The alluvial deposits of the Colorado River are mapped as either sand or gravel based on surface composition...
Expert judgment data for a Bayesian decision network of prescribed fire in Gulf of Mexico marshes (ver. 1.1, August 2025) Expert judgment data for a Bayesian decision network of prescribed fire in Gulf of Mexico marshes (ver. 1.1, August 2025)
This data set was collected as part of structured decision-making workshops designed to build a Bayesian Decision Network of prescribed fire in high marshes of the Gulf of Mexico. As part of a formal elicitation process for expert judgment, workshop participants independently created conditional probability tables based on a conceptual model of prescribed fire in high marsh ecosystems...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional and continuous oil and gas resources in in the Lewis Shale of the Southwestern Wyoming Province, Wyoming and Colorado. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The...
Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – December 2021, Mid-construction #2 Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – December 2021, Mid-construction #2
In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction light detection and ranging (lidar) survey of the streambanks...
