| Abstract | Cruise SO233 comprised petrological, volcanological, geochemical, geochronological, and biological studies in the area of the aseismic Walvis Ridge and the adjacent ocean floor. The major targets of the cruise were to test for age progressive volcanism along the ridge, to differentiate between classical hotspot and plate fracturing models for its formation, and to constrain the origin and temporal and spatial evolution of melting conditions and source compositions. Since the EM120 did not work properly on the precursor cruise SO232, two technicians from Kongsberg though it impossible to improve the quality of the EM120 data since the major problem is the aging of the transducer being installed beneath the vessel and therefore out of reach. Therefore bathymetric mapping could unfortunately only be conducted in reduced extent and quality on cruise SO233. |
