Abstract:
Multibeam data were collected during R/V Polarstern cruise ANT-XXVI/2 along track lines of about 9,270 NM total length along transits, survey profiles and during stationary work. Departing in Punta Arenas the ship headed for its first main working area, the Eltanin Impact Area. In the following the ship's track crosses Pacific Antarctic Ridge and the corresponding fracture zones several times before arriving in Wellington.
The refraction correction was achieved utilizing CTD profiles or by the system's own cross fan calibration. The quality of data might be reduced during bad weather periods or adverse sea ice conditions. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position.

Comment:
The raw multibeam sonar data in SURF format are compressed as TAR archive with GZIP. One dataset contains a measurement period not exceeding eight hours. SURF data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/). The source code for an application programming interface (API) to read and write SURF data is released by the Hydrosweep manufacturer Atlas Hydrographic, Bremen, and published under the GNU GPL.
