The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set o

This XYZ dataset, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provides lidar-derived seamless (bare earth and submerged) topography for the Chandeleur Islands in Louisiana. Elevation measurements were acquired by the first-generation Experimental Advanced Airborne Research Lidar (EAARL) on September 4 and 5, 2010. The data were collected as part of a se

This data release includes marine geophysical data collected on three research cruises conducted in 2010 and 2012 between Point Arena and Cape Mendocino. The overall goal of this research is to better understand the northernmost section of the San Andreas Fault (SAF). In 2010, the USGS collected seismic-reflection profiles crossing the SAF at 1 km spacing from Point Arena to Fort Bragg (survey B-5

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal

Bacillus species and B. anthracis presence/absence data were determined in 4,770 soil samples collected across the contiguous United States in collaboration with the PCR data for Bacillus species and B. anthracis rpoB gene PCR amplicon detection was reported as non-detect (n), low (l), medium (m), and high (h). Results for both pag and lef genes of the pX01 plasmid were reported by the University

Water velocities were measured in the Des Plaines River from approximately river mile 286 to river mile 284 on October 1921, 2015 using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi

The U.S. Geological Survey (USGS) Fort Collins Science Center created a national data set of the footprint area of solar arrays for the Bureau of Land Managements National Operations Center. We identified potential solar facility locations for the conterminous U.S. using the U.S. Energy Information Administration (EIA) utility-scale facilities data from 2015. The footprint area of each solar array

Water velocities were measured along the Illinois and Des Plaines Rivers using a Teledyne Rio Grande 1200 kHz acoustic Doppler current profiler (ADCP). ADCP data were collected in reciprocal pairs along crosssections and along approximately streamwise-oriented lines between crosssections at the following locations: (1) the Dresden Island Pool of the Des Plaines River on May 14, 2013 and July 3

Streamflow and phosphorus concentrations were monitored in the Assabet River in central Massachusetts in order to evaluate concentrations and loads in the river before, during, and after changes in the amount of total phosphorus that was discharged to the river from three wastewater-treatment plants. At four locations the U.S. Geological Survey collected weekly flow-proportional, composite samples

Water velocities were measured in the Calumet Harbor for 5 dates in 2015 and 2016 using Teledyne Rio Grande 600 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in cooperation with the US Army Corps of Engineers-Chicago District. ADCP data were collected on the following dates:

On August 31, 2015, USGS Illinois Water Science Center staff deployed a 2000 kHz side-looking acoustic Doppler velocity meter (ADVM) in the Chicago Sanitary and Ship Canal (CSSC) at the Electric Dispersal Barrier System (EDBS). These data were collected as a fully loaded commercial barge tow traversed the EDBS and passed the ADVM three times, and as several smaller vessels and an unloaded barge to

This data set includes data from three waterfowl species (northern pintail, American wdgeon, lesser scaup, green-winged teal and mallard) that were captured in Interior Alaska in 2010, then measured and sampled for blood parasite and avian influenza infections.
