Ziel der Reise / Objectives of Cruise:

Systematic petrological/geophysical attempt to conduct extensive experiments in order to better understand the Mesozoic/Cenozoic "hotspot" volcanism in the South Atlantic. So far only few, randomly distributed samples exist from the Shona Ridge-Meteor Rise-Agulhas Ridge-Cape Rise and the Discovery Seamounts exist to better constrain their temporal evolution. 1)Within the petrological programme the Shona, Discovery and Cape Rise Seamounts were dredged with variable success. In addition, dredge samples from the southern Walvis Ridge were obtained. 2)Seismic reflection and refraction (OBS) experiments were conducted across the Discovery and the western Cape Rise Seamounts/Agulhas Ridge were conducted to determine the deep crustal structure of these feeatures. Similar experiments (1x refraction line, 3 seismic reflection lines) were measured across the southern Walvis Ridge. SeaGeophysical information in these areas are almost absent. This is especially true for deep seismic and multichannel seismic data. Potential field data were acquired along the entire ship track. Helicopter borne magnetic data were acquired parallel to the dredging operations.
