Ziel der Reise / Objectives of Cruise:

AL527 was a student cruise, organized by the University of Kiel for bachelor students in the 'Physik des Erdsystems' program. The main objective is to familarize the students with marine geophysical methods. This year, the conveyed methods include a seismic system using small airguns and a Norbit shallow-water echo sounder in addition to ALKOR's permanently installed systems, such as the EK60 fishfinding echo sounder and the Innomar sediment echo sounder. The cruise pursues two specific goals. On one hand, we are trying to find out what has happened to Geomar's biological submarine observatory off Boknis Eck. The observatory consists of an 8m-high tower for instruments and two 1x2m steel cages, for power supply and housing of several scientific sensors. The connection to the observatory broke down the previous week and since then, research divers only found broken remains of the steel cages. On the other hand, we are exploring potential areas for future experiments, funded by the ministry for economy (BMWi), in which air will be injected into the seafloor to assess the seafloor response. Those experiments will presumably take place on a larger research vessel next year.
