During the cruise we have used the 1Km resolution bathymetric data of the SRTM30-PREDICTED dataset by [Becker et al.(2008)]. The lat-lon data were used to produce GMT Netcdf grids, and, after conversion to the UTM33 Projection, for input to the PDS-2000 software. Therefore, we have been able to use them for navigation and planning.
The datum was set to WGS84 and the UTM (zone33) was chosen for navigation, display, and data acquisition. The time zone was set to the UTC for the instrumental data acquisition.
The positioning maps and bathymetric images were produced with GMT [Wessel and Smith (1995)]. The multibeam data were pre processed on board by the PDS2000 and GMT software and ISMAR's routines and scripts, using the PDS-2000 production DTMS or XYZ ASCII converted data.
Photographs and video were taken by digital cameras and video-camera.
