Data

This data release includes boomer 3D seismic data collected in 2012 offshore Point Sal, central California as part of PG&Es Central California Seismic Imaging Project (Pacific Gas and Electric Company PG&E,2014). The U.S. Geological Survey conducted advanced post-processing and neural-network fault calculations on the data for improved fault detection (Kluesner and Brothers, 2016)...

This data release includes the results of analysis of video data conducted by Oregon State University and the geo-habitat interpretation of multibeam echo sounder (MBES) data conducted by the USGS. The data were collected in 2014 and were published in Cochrane and others (2015). This data release accompanies report that describes the project and results in detail (Cochrane and others...

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for a portion of the Texas coastline. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 17th, 2008, following Hurricane Ike landfall.

These datasets, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for a portion of the Texas coastline. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on September 27th and 28th, and October 2nd, 2005, following Hurricane Rita landfall.

Coastal erosion is a persistent process along most open-ocean shores of the United States and affects both developed and natural coastlines. Along the Arctic coast of Alaska, coastal erosion is widespread and threatens communities, defense and energy-related infrastructure, and coastal habitat. As the coast changes, there are a wide range of ways that change can affect coastal...

The Atlantic Beach artificial reef, located on the sea floor 3 nautical miles south of Atlantic Beach, New York in about 20 meters water depth, was built to create habitat for marine life. The reef was originally created by placing heavy materials such as tires, automobile bodies and other vehicles, barges, and rock from a dredging project on the sea floor. In 2000, the U.S. Geological...

This data release includes geospatial datasets that were created to analyze wetland changes along the Virginia and Maryland Atlantic coasts between 1984 and 2015 as part of the U.S. Geological Survey's (USGS) Barrier Island and Estuarine Wetland Physical Change Assessment. Wetland change was determined by assessing two metrics: wetland persistence and land-cover switching. Because...

Acoustic Doppler Current Profilers (ADCPs) and Pressure loggers were deployed at Crocker Reef, a senile (dead) barrier reef located in the northern portion of the Florida Reef Tract during December 12, 2014 to January 30, 2015. A pressure logger was deployed in the deepest part of the fore reef at a water depth of 14 m. This logger configured to measure pressure at a rate of 2 Hz to...

Attenuation Factor (AF; Rao and others, 1985) and DRASTIC (Aller and others, 1987) models were developed for the Upper Floridan aquifer within the Southwest Florida Water Management District (SWFWMD) boundaries. The models were compared to assess the ability of each of these models to indicate the vulnerability of groundwater resources to contamination by Ethylene Dibromide and Bromacil...

A multibeam survey was carried out in 2002 to map the bathymetry and backscatter intensity of the sea floor of the Hudson Canyon and adjacent slope and rise. The Canyon begins on the outer continental shelf off the eastern coast of the United States at about 100-meter (m) water depth and extends offshore southeastward across the continental slope and rise. The survey covered an area...

Water-level gauges were deployed at two sites in West Falmouth Harbor between May and October 2016. Two sequential deployments were required to provide measurements for the entire period. One gauge was mounted under the town-owned West Falmouth boat dock and the other on the private Associates dock near the mouth of the Harbor. Each gauge supported two pressure sensors mounted in a...

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the...
