Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Alaska coastal orthoimagery and elevation data: Icy Cape to Cape Prince of Wales, 2016 Alaska coastal orthoimagery and elevation data: Icy Cape to Cape Prince of Wales, 2016
This data release presents orthoimagery and elevation data based on aerial imagery of the Alaska coastline between Icy Cape and Cape Prince of Wales. These data products and the source aerial imagery were generated by Fairbanks Fodar for the U.S. Geological Survey. Aerial imagery was collected in 2016 between August 29 and September 4 and extends from the shoreline to 400-4000 meters...
Spatial and Temporal Data on Hydraulic Fracturing Fluid Types and Amounts Injected into Oil and Gas Wells Across the U.S., 2015-2019 Spatial and Temporal Data on Hydraulic Fracturing Fluid Types and Amounts Injected into Oil and Gas Wells Across the U.S., 2015-2019
Hydraulic fracturing is a treatment method used to stimulate production from oil and gas wells. Hydraulic fracturing involves injection of treatment fluids mixed with propping agents under high pressure into perforated portions of the wellbore. This method causes the reservoir rocks to fracture and the hydraulic fracturing fluids and propping agents to enter the fractures. Subsequently...
Threshold friction velocities for aeolian transport of river-sourced sand, with related moisture content, grain size, topographic, and wind data from Lees Ferry, Arizona Threshold friction velocities for aeolian transport of river-sourced sand, with related moisture content, grain size, topographic, and wind data from Lees Ferry, Arizona
These data were compiled to investigate the control of drying on the aeolian transport of river-sourced sand. Objectives of our study were to to examine aeolian sediment transport during a five-day period of low steady river flow on a river sandbar and adjacent aeolian dunefield. These data represent the observed and theoretical threshold fiction velocities for aeolian sediment transport...
Russian River Integrated Hydrologic Model (RRIHM): Groundwater & Streamflow Observations Russian River Integrated Hydrologic Model (RRIHM): Groundwater & Streamflow Observations
The Russian River Watershed (RRW) covers about 1300 square miles (without Santa Rosa Plain) of urban, agricultural, and forested lands in northern Sonoma County and southern Mendocino County, California. Communities in the RRW depend on a combination of Russian River water and groundwater to meet their water-supply demands. Water is used primarily for agricultural irrigation, municipal...

Optimization simulations to estimate maximum brine injection rates in the Illinois Basin Optimization simulations to estimate maximum brine injection rates in the Illinois Basin
We developed a methodology to estimate maximum brine injection rates in subsurface formations across wide geographic areas using inverse modeling-based optimization techniques. We first defined geographic areas where groundwater was too saline to meet the standard for drinking water and where sufficient confining units existed above and below the injection layers. We then assumed...
