Abstract:
Multi-beam bathymetric data, using the ship's Sea Beam System, was
acquired during three cruises to the Antarctic as part of the
U.S. GLOBEC Southern Ocean study 2001-02. The general survey area
includes the continental margin to the west of the Antarctic Peninsula
extending from the northern tip of Adelaide Island to the southern
... portion of Alexander Island, and Marguerite Bay. Although the Sea Beam
System acquired data continuously, only the data south of 65 South has
been edited and final processed.
The final processed data set is archived on 8mm tape having the
following attributes:
MBIO Data Format ID: 43
Format name: MBF_SB2100B2
Informal Description: SeaBeam 2100 series vender format
Attributes: SeaBeam 2100, bathymetry and amplitude, 151
beams bathymetry, binary, SeaBeam Instruments and L-DEO.
The software used to process and display these multi-beam data (in
the above referenced format) is available as shareware from the
following web site:
Due to the nature of this data set, it has been deposited with
NOAA's National Geophysical Data Center (NGDC) in Boulder, Colorado
for archival and dissemination purposes. Users seeking these data
should contact the NGDC (http://www.ngdc.noaa.gov/) referencing the
data collected during the following cruises:

RVIB Nathaniel B. Palmer / NBP0202 / Apr 09-May 21 2002
Note: Cruise dates are generally longer then dates of data.
User Caution:
This is a very large data set and only individuals with experience
in working with multi-beam data should attempt to acquire it. As an
alternative, Mr. Bolmer is making a revised bathymetric map of the
region using all available data. See web site:
