High-resolution geophysical data collected along the Delmarva Peninsula 2015, U.S. Geological Survey Field Activity 2015-001-FA

June 3, 2016

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 system evolution at storm-event and longer timescales. Geophysical data collected during the cruises include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection profiles, grab sample and bottom photograph data. Preliminary datasets of backscatter and bathymetry from the 2015 survey are released here to the public and collaborators while final datasets for all data collected in 2015 will be released in 2016. More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: http://woodshole.er.usgs.gov/project-pages/delmarva/, http://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA and http://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA.
