Ziel der Reise / Objectives of Cruise:

Cruise ALKOR 436 was dedicated to the testing of a new flexible monitoring tool for environmental parameters such as off shore gas concentrations which is constructed and build in the framework of the German nationally funded project "FlexMoT". For the testing of the first prototype a strong sea floor source of methane was required. The well site 22/4b ("Blow Out") in the British EEZ is such a place with a permanent gas flow from the sea floor to the atmosphere. The well site 22/4bhas been intensively studied by our institution during previous research cruises with the German RV ALKOR (Cruise No.: 66, 259, 290, 374, 387). During cruise AL 436 some short surveys with CTD/RO water sampler and deployments of a testing type of the FlexMoT observation system and a small GEOMAR lander for control measurements were carried out. The cruise started and ended in Kiel (Germany) and led directly to the Blow Out in the northern North Sea. Station work (3 days) was carried out directly in or a within 1000m distance of the Blow Out. On a our transit to the working area a depression front with gale blocked our way through the Skagerrak, which caused an overnight stay in Kristiansand (Norway) waiting for favourable wind conditions.
