The marine geophysics group of the Kiel university has performed 3 high resolution seismic surveys (September/96, January/97 and March/97) at the Arkona Basin, Baltic Sea. The surveys were performed with the RN Alkor and aimed at the detection of sedimentary and structural features that would give more information about the development of the Baltic Sea. For the acquisition of the data two different seismic systems were used (3,5 kHz and Boomer). The main objective of the surveys was the localisation of geological structures that may provide more information about the development of the Baltic Sea, as well as the identification of gas-charged sediments. The results showed the occurrence of mud diapirs and paleo-channels of different sizes, sharp contacts, and the occurrence of several gas-charged areas.
