Ziel der Reise / Objectives of Cruise:

The RV METEOR cruise M152/2 strived for a better understanding of the life cycle of submarine volcanoes and their effect on the oceanic lithosphere in the oceanic intra-plate setting of the Bathymetrists Seamounts and the Sierra Leone Rise. The aims were: 1) to understand the interaction between crustal thickness, tectonics and volcanic phases, 2) to investigate the chronological evolution of individual seamounts and seamount chains, 3) to study the structural growth process of elongated seamounts, 4) to review slope failures and resulting mass flow processes, 5) to sample long-lived organic substances of terrestrial origin. We addressed these objectives by high-resolution reflection seismic, parametric echosounder (PARASOUND), multi-beam (SIMRAD EM122), gravity and magnetic profiling as well as rock sampling. We further collected long-lived organic substances by means of surface water and air sampling. After a 4 day long transit to the Bathymetrists our working program started on January 7. We collected more than 4000 km of multi-channel seismic data and carried out 14 dredge stations. Scientific program ended on February 1st and we called Walvis Bay harbor on February 11.
