Dynamics of the Ocean Floor
R/V Pourquois Pas?
Cruise: - Project: ODEMAR
Chief Scientist: Dr. Javier Escartin / GEOMAR: Dr. Sven Petersen
Duration: 17.11.2013-22.12.2013 Ports: Cap Verde - Cap Verde
Programme: Structure, formation and evolution of oceanic detachment faults and their connection to the formation of oceanic lithosphere. High-resolution mapping of detachments and associated hydrothermal fields in the Central Atlantic Ocean (13°N) using the autonomous underwater vehicle AUV ABYSS.
- AUV ABYSS, ROV Victor
Cruise: SO-232 Project: SLIP
Chief Scientist: Dr. Gabriele Uenzelmann-Neben (AWI), GEOMAR: Dr. Reinhard Werner
Duration: 30.03.2014 - 13.05.2014
Ports: Durban (South Africa) - Cape Town (South Africa)
Programme: R/V SONNE cruise SO-232 is part of the cooperative project SLIP between GEOMAR and the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI). The SO-232 cruise focuses on reflexion seismic profiling and hard rock sampling at the Mozambique Ridge in the Southwest Indic. SLIP will contribute to a better understanding of the evolution of the Mozambique Ridge and the accompanying volcanism during the opening of the southern ocean as well as the connection between volcanic-tectonic activities of the ridge and the modifications in the ocean current systems.
Cruise: SO-233 Project: WALVIS II
Chief Scientist: Prof. Kaj Hoernle
Duration: 14.05.2014 - 21.06.2014
Ports: Cape Town (South Africa) - Walvis Bay (Namibia)
Programme: R/V SONNE-cruise SO-233 focuses on systematic sampling of the magmatic basement of the c. 1.500 km long eastern part of the Walvis Ridge in the Southeast Atlantic. The WALVIS II project continues and broadens our previous studies of the Walvis Ridge and aims (1) to test for age progressive volcanism along the ridge, (2) to differentiate between classical hotspot and plate fracturing models for its formation, and (3) to constrain the origin and temporal and spatial evolution of melting conditions and source compositions (in particular for the EM-I endmember and for zonation of mantle plumes). Accompanying to the basement sampling, biological sampling will be conducted by the Museum für Naturkunde Berlin to better constrain the biodiversity of the Southeast Atlantic.
Cruise: SO-234/1 Project: SPACES
Chief Scientist: Dr. Reinhard Werner
Duration: 22.06.2014 - 06.07.2014
Ports: Walvis Bay (Namibia) - Durban (South Africa)
Programme: R/V SONNE cruise SO-234/1 continues the studies of the temporal and geochemical evolution of the Walvis Ridge conducted on SO-233 (see above) and is broadened by biological studies of deep sea fish. The biological work will be carried out by the University of Tübingen and aims to get a better knowledge of adaptations of visual systems in mesopelagic animals to bioluminescence. SO-234/1 is a training and capacity building cruise for students from southern Africa and Germany in the framework of the SPACES programme (Science for the Assessment of Complex Earth System Processes), a cooperative research project initiated by the relevant ministries in Namibia, South Africa, Angola and Germany.
