Data Type(s): Sonar: Multibeam, Sonar: Sound Velocity, Location-Elevation: Navigation

Scientific Purpose/Goals: Map the shelf-edge offshore Virginia and Maryland in support of BOEMRE studies of the area


Start Date: 2011-06-04

Start Port/Location: Charleston, SC

End Date: 2011-06-17

End Port/Location: Charleston, SC

Equipment Used: Simrad EM1002, Reson 7125-SV, DGPS

Summary of Activity and Data Gathered: Approximately 2,500 km of high resolution multibeam bathymetry data were collected covering Baltimore, Washington and Norfolk canyons and areas of the shelf and shelf-edge in between them. Additional data was collected off Cape Hatteras and during the transit legs from and to Charleston, SC.
