Methane discharge from a submarine mud volcano - A multiple-method approach

Submarine methane discharge manifests in different forms and occurs on different spatial scales. Physical, biological and geochemical processes interact at the seafloor. Comprehension and description of such complex systems requires a suite of different sampling and in situ measurement technologies. As an example, investigations carried out at a submarine mud volcano are described. Multi-method investigations are challenging in respect to handling, technical inter-operability as well as synchronization and integration of the data obtained.
