Ziel der Reise / Objectives of Cruise:
Cruise M88/2 was dedicated to conduct controlled source electromagnetic (CSEM) measurements to study the electrical resistivity structure of possibly gas containing shallow sediments in the German North Sea sector. The experiments are part of the joint venture project "Geopotential German North Sea" (GPDN), coordinated at BGR. During the 13 days cruise measurements were conducted along previously obtained seismic profiles in two working areas close to Helgoland showing strong amplitude anomalies within the first 200 m below the seafloor. Two different types of seabottom-towed CSEM systems were used. Further deployments with the CTD and a methane sensor were taken at several sites. Multibeam and Parasound data were recorded along all CSEM profiles.
