Multibeam Bathymetry

newMultibeam bathymetric data at NGDC can now be selected via an interactive map (ArcIMS) Web interface. Data selections are downloadable for free. An on-line Autochart custom mapping feature is also available. See the "ArcIMS Map" link at left.

NGDC is the US national archive for multibeam bathymetric data and presently holds over 1.6 million nautical miles of ship tracklines (660 surveys) received from sources worldwide.

The interactive map for these data displays the geographic locations of multibeam bathymetric data by institutional source or by ship name. Data NOT at NGDC but in the GEODAS inventory can also be viewed (see link at left) in either .pdf form, or by searching for multibeam bathymetric data not at NGDC.

NGDC accepts new multibeam bathymetric data that will be provided through this map. We prefer data in a format supported by the MB-System software package developed at LDEO used to process and display multibeam bathymetric data.

Please send any comments you may have on the interactive map and/or corrections you may have for these data to William.T.Virden@noaa.gov, 303-497-7278.
