| 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 measured during R/V Polarstern cruise ARK-XXIV/3 along track lines of 6968 NM total length in the Northern Greenland Sea. Data were achieved mainly in the area of the Jan Mayen and the Greenland fracture zone, at the East Greenland margin and the Boreas Basin. Bathymetric surveys were carried out at Knipovich Ridge during several days completive to former Polarstern cruises, resulting in a surveyed area of 15,137 km2 in total. A systematic survey was carried out at the entrance of Kong Oscar Fjord. 11 hours survey was conducted at the shelf east of Dijmphna Sund at 80.40°N/10.33°W to complete multibeam data achieved in 1997. The multibeam sonar system Hydrosweep DS-2 was operated using 59 beams and 90° aperture angle, 120° in shallow water areas. The refraction correction was achieved utilizing the system's own cross fan calibration. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position. |
