Expedition AL412 with RV ALKOR: ECO2

Chief Scientist: Dr. Peter Linke, GEOMAR Kiel

The expedition AL412 with RV ALKOR was conducted within the framework of the EU project ECO2. After mobilisation of the ROV PHOCA system and test dive during minus degrees in Kiel, RV Alkor left port on the 23rd of March, 2013 heading towards the working areas in the North sea. These included the so called "Blow Out Crater" (in the British Sector) and the Utsira sand stone formation (Sleipner) (in the Norwegian Sector).

The main objective of the expedition was the investigation of a late-winter situation, during which the water column is barely layered, and large amounts of greenhouse gases may evaporate into the atmosphere. Tasks of ROV PHOCA inlcuded the sampling of sediments, gases and bottom water, on-line measurements of methan and CO2 and the deployment and recovery of autonomous tools.
