Ziel der Reise / Objectives of Cruise:

The R/V SONNE expedition SO-249 is part of the research project BERING, conducted in the framework of the Russian-German Agreement on Marine and Polar Research and in close cooperation with U.S. American colleagues. The overarching goal of BERING is to elucidate the magmatic and tectonic evolution of the Bering Sea and its margins over the past ≥50 m.y. In particular, BERING investigates the physical and chemical conditions that control the development of subduction zones, including subduction initiation, evolution of mature arc systems, and the impact of subduction volcanism on the environment. Cruise SO-249 Leg 2 mapped and sampled magmatic structures in the westernmost Aleutians and in the western Bering Sea using a SIMRAD EM 122 echo sounding system, a ATLAS PARASOUND sub-bottom profiling system, and chain bag dredges. A minor biology program intended to describe the benthic diversity of deep-sea invertebrates in the working area by collecting macro benthos from the dredged rocks. The on shore work program at GEOMAR and cooperating institutions will include geochronological, petrological and geochemical studies on igneous samples obtained during the cruise. The results of BERING will be integrated with those of previous campaigns (e.g. KOMEX, KALMAR), and work carried out within the World Oceans and GeoPRISMS initiatives.
