| Purpose | Multibeam data were collected to extend the global database of seafloor topography and to provide high resolution bathymetry for the expedition's scientific program. |
| Abstract | Multibeam data were collected during R/V Polarstern cruise ANT-XVII/3. Data recording was executed on transit from Cape Town to Neumeyer Station and from central Weddell Sea to Bransfield Strait. In Bransfield Strait and around Austaasen Bank and Norwegia Bank systematic profiling was performed. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. Because of a hardware problem the time stamps within the files are erroneously increased by one day. This error was fixed for filenames but not for timestamps of events within the files. One file contains a measurement period not exceeding eight hours. The dataset consists of 122 files in ATLAS SURF format which are compressed with GZIP to size of 1.60 GB. SURF data files can be processed using the software packages CARIS HIPS/SIPS or with the open source software package MB-System. |
