Data

Underwater video imagery was collected in March 2014 in the nearshore waters of Faga'alu 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. This data set includes 2,119 still images extracted from the video footage every 10 seconds and an Environmental Systems Research Institute (ESRI)...

The seven files included in this U.S. Geological Survey data release are data from a set of sediment cores acquired from the continental slope, offshore Los Angeles and the Palos Verdes Peninsula, adjacent to the Palos Verdes Fault. Gravity cores were collected by the USGS in 2009 (cruise ID S-I2-09-SC; http://cmgds.marine.usgs.gov/fan_info.php?fan=SI209SC), and vibracores were collected...

The National Archive of Marine Seismic Surveys (NAMSS) is a marine seismic reflection profile data archive consisting of data acquired by or contributed to U.S. Department of the Interior agencies. The archived data were collected from 1975 to the present. They include marine seismic reflection profile data acquired originally for purposes of oil and gas exploration within the U.S...

This USGS Data Release presents data collected from bathymetric and topographic surveys and the resulting digital elevation model for the Little Holland Tract in the Sacramento-San Joaquin River Delta, California. During May and June of 2015, a team of scientists from the USGS Pacific Coastal and Marine Science Center (PCMSC) conducted multiple surveys (USGS Field Activity 2015-642-FA)...

High-resolution swath bathymetry and backscatter were collected in the Mouth of the Columbia River (MCR) as part of the Office of Naval Research (ONR) funded River and Inlet Dynamics Experiment in 2013. The goal of the U.S. Geological Survey's component of the research was to evaluate the various hydrodynamic and sediment transport processes in the Columbia River estuary entrance using a

Seafloor substrate data available from multiple sources has been modified for the purpose of characterizing the seafloor for the Regional Importance of Manmade Structures as Rockfish Nurseries study. Substrate was classified from multibeam sonar data using a video supervised numerical classification methodology. The overall objective of this study is to begin to integrate region-wide...

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...

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...
