Data

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

These data depict littoral cells along the West Coast of the United States, as segments of the shoreline of Washington, Oregon, and California. A littoral cell is a reach of the coast that is isolated sedimentologically from adjacent coastal reaches and that features its own sources and sinks. Isolation is typically caused by protruding headlands, submarine canyons, inlets and some river mouths th

Underwater video imagery was collected in March 2014 in the nearshore waters of Fagaalu Bay on the Island of Tutuila, American Samoa, as part of the U.S. Geological Survey Coastal and Marine Geology Program's Pacific Coral Reefs Project. Included here are 40 video files in .mpg format and an Environmental Systems Research Institute (ESRI) shapefile with location (navigation) points every two secon

These data are the results of a modified Delphi survey in which expert opinion was solicited on the occurrence and frequency of recreational activities in brown bear habitats and their potential impacts. Twelve bear experts were surveyed and identified by either 1) their scientific publications on the impacts of one or more human recreational activity on bears, or 2) their experience in managing b

The files in this data release are the raw and processed DNA sequence files referenced in the submitted journal article by Kellogg et. al. titled "Bacterial Community Diversity of the Deep-Sea Octocoral Paramuricea placomus." They represent a 16S rRNA gene amplicon survey of the coral's microbiome completed using Roche 454 pyrosequencing with titanium reagents. Baltimore Canyon is in the Atlantic

These data were used to explore environmental effects on fix success rates (FSR) across a wide range of environmental conditions, desert to alpine biomes, and cover the full range of potential data loss (0-100% FSR) for global positioning system (GPS) bias correction of terrestrial GPS-derived, large mammal habitat use. Also, these data were subsequently used to evaluate patterns in missing data t

This mosaic, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provides lidar-derived submerged topography for a portion of the submerged environs of Saint Thomas, U.S. Virgin Islands. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on March 7, 8, 11, 12, 13, 14, 17, 18, and 24, 2014, in co

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Beaumont and Lower Neches River Units of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 11, 15, 17, 18,

Swath bathymetric data were collected offshore of Fire Island and western Long Island, New York in 2014 as a part of a collaborative effort between the U.S. Army Corps and USGS to assess the impact of Hurricane Sandy on this coastal region. These data were compared to swath bathymetric data collected by the USGS in the same area in 2011 to evaluate any modifications to the inner continental shelf,

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Neches Bottom and Jack Gore Baygall Unit of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 11, 15, 17, 1

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Lance Rosier Unit of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 15, 21, 22, 25, 26, and 30, 2014, in

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Turkey Creek Unit of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 19, 21, 22, 25, 26, and 29, 2014, in
