Ziel der Reise / Objectives of Cruise:

Cruise Leg So 232 with RV Sonne, leaving Durban, South Africa on 30.3.14, returning to Cape Town, South Africa on 13.5.14, comprised seismic reflection and petrological studies of the Mozambique Ridge, a Large Igneous Province (LIP) in the south western Indian Ocean. The Mozambique Ridge consists of four major geomorphological units: Segments 1 to 4. The major goal of the expedition has been the role of the Mozambique Ridge within the break-up of Gondwana and its direct and indirect influence on climate and oceanic circulation. Seismic reflection data were gathered to study the basement structure of the ridge, its development after the initial formation as well as the distribution of sedimentary sequences and depositional environment. Petrological dredge samples will provide information on composition and age of the Mozambique Ridge. In total 4200 km of high resolution seismic reflection data were recorded. Bathymetric data were recorded parallel to the seismic profiling. Both datasets have additionally been used to pick significant locations for the petrological sampling. 59 dredges have been taken to sample the basement.
