PurposeResearch
ObjectivesCatastrophic large-scale landslides are a fundamental process in the formation of many oceanic islands. The main aim of cruise CD168 was to carry out an initial reconnaissance survey of the influence of landsliding on the Cape Verde islands, in the eastern central Atlantic, in an area where subaerial evidence suggests the occurrence of landslides but where limited previous offshore work had been undertaken. The main objectives of the study were to determine the extent of submarine landslides, the nature of the landslide processes, and the overall influence of landsliding on island evolution. A short survey of the distal part of the Cape Timiris Channel, at 20° 30' N and just outside the Mauritanian 200 mile limit, was carried out during the passage between Gran Canaria and the Cape Verdes.
