Ziel der Reise / Objectives of Cruise:
A physical oceanography cruise to investigate oceanographic conditions ( currents, waves, resuspension/erosion ) during stormy events near the gas pipeline ZEEPIPE I in the German North Sea sector. Results are needed to increase our knowledge about the developing of freespans below pipelines.
