Multibeam Sonar
Multibeam sonar uses acoustic energy to collect high resolution measurements of the depth and character of the ocean floor.

the multibeam is mounted.
In 2007 Burroughs & Chapin Center for Marine and Wetland Studies received an equipment grant from the National Science Foundation for the purchase of a Multibeam Sonar along with acoustic current sensors. The addition of a Multibeamn Sonar to existing geophysical capabilities puts the Center on the cutting edge of marine research.
Multibeam Bathymetry was collected aboard the NOAA ship R/V Nancy Foster in cooperation with Gray’s Reef National Marine Sactuary (George Sedberry), South Carolina Department of Natural Resources and funded through NOAA’s Office of Ocean Exploration.
This dataset was collected in conjunction with the shelf edge reef data. It shows a large scour feature known as the Georgetown Hole and is created
by current eddies from the Gulf Stream. At the shallower depths several Iceberg Keel Marks were discovered on the seafloor. On the image above
a few examples have been identified.
