Ziel der Reise / Objectives of Cruise:

The H?kon Mosby Mud Volcano (HMMV): Cold seep mud volcano activity and it's anoxic microbial systems This cruise leg ARK XXII/1b of RV "Polarstern" was part of the EU funded project HERMES, an integrated project aiming at research on ecosystems lying in the deeper ocean section. At the same time it contributes to the coordinated activities carried out during the International Polar Year (IPY) in 2007. The shipboard scientific party consisted out of participants from Belgium, France, Germany and Norway. Major aim was to further improve our understanding of the cold seep ecosystem at the H?kon Mosby Mud Volcano and to characterise the environment (geological setting , sediment compositions) associated with chemosynthetic communities. Other research objectives were related to the assessmeht how environmental factors influence species diversity and abundance of microbial, protozoan and metazoan communities. Furthermore, the identification of how chemosynthetic communities respond to variations in fluid chemistry and flux at the sediment interface was in focus. Other objectives aimed at a better derstanding of what are the consequences of environmental interactions on substrate modification, benthic diversity and ecosystem production at local and regional scales. The evaluation of the capacity of seep ecosystems to remove carbon from methane sources and the role of this process in the global ocean carbon budgets was undertaken.
