Ziel der Reise / Objectives of Cruise:
Main topic of MARIA S. MERIAN leg 11/2 was the preparation of an IODP expedition entitled 'Neogene Paleoclimate and sediment transport at the continental margin of NW Africa'. Between Cap Bojador, southeast of the Canary Islands, and the deltas of rivers Senegal and Gambia we collected seismic data in five different areas as a presite survey. Another topic of the cruise was the investigation of particle transport and characteristics of the upwelling area off Cap Blanc. Longterm moorings of sediment traps, oceanographic and optical sensors at stations CB (since 1988) and CBi (since 2002) had to be renewed. Additional samples of particles in the water column and at the sediment surface should been taken by water samplers, in-situ pumps, and multicorers.
