Statement: NGDC's global database of multibeam swath sonar bathymetric surveys
Abstract: NGDC is the US national archive for multibeam bathymetric data and presently holds over 15.7 million nautical miles of ship tracklines (1187 surveys) received from sources worldwide.
In addition to deepwater data, the multibeam database also includes hydrographic multibeam survey data from the NOS. Associated NOS data products, including 3D images and grids, are available via the NOS Hydrographic Survey Data Map Service.
