Data

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...

The deployment of Landsat and other earth-observing satellites within the last few decades has provided an opportunity to observe barrier islands at frequent intervals, often many times a year. A variable of persistent interest as a metric for coastal erosion or change is the shoreline. Shorelines derived from imagery have value to resolve coastal changes. This data release includes...

Many barrier islands in the United States are experiencing substantive erosion and elevation loss due to storm surge, waves, and sea-level changes; this is particularly true for the deltaic barrier system in Louisiana. Breton Island is located near the mouth of the Mississippi River in the southern end of the Chandeleur Island chain in southeast Louisiana. This report expands on previous

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...

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...

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...
