Ziel der Reise / Objectives of Cruise:

ATAIR 022: The Federal Maritime and Hydrographic Agency (BSH) on behalf of the Federal Network Agency (BNetzA) and the Federal Ministry of Economic Affairs and Energy, respectively, is in charge of the preliminary investigation of sites for future offshore wind farms. The preliminary investigation of sites encompasses, beside others, hydro-acoustic and high-resolution reflection seismic measurements. In order to adapt upcoming tenders to the specific geological conditions of each wind farm area, to refine current geophysical and geotechnical contracts as well as to assess the quality of future offshore campaigns, BSH collects hydro-acoustic and seismic data in cooperation with the University of Bremen for planning and reference purposes. In this context high-resolution multichannel seismic datasets - using a Sparker as well as a micro GI pulser as seismic sources - as well as sediment echosounder and multibeam echosounder data have been recorded in the wind farm area N-21 as well as potential wind farm areas alongside the shipping route SN10 according to the Site Development Plan (FEP). Furthermore, an Ocean-Bottom-Node (OBN) system has been temporally deployed for refraction, shear-wave and Scholte-wave seismic tests. (FEP = Site Development Plan (for offshore windfarms)) Seismic survey: FEP area N-21 and shipping route SN10 OBN test: FEP area N-9
