It is proposed to the Dutch Foundation for Marine Research SOZ to organize an expedition to the Kenyan coastal area in 1991. The exact timing of the expedition depends on the availability of the research vessel Tyro. Suitable periods would be December-March (May) and/or September-December. The aim of the expedition in general is to provide basic data on the structure and functioning of marine systems along the East-African coast, and, in particular, to evaluate the ecological effects of the rivers on these marine systems. As a result of human activities, the composition of the riverine water has strongly changed; it is expected that this will have profound effects on the coastal ecosystems. The continental shelf is limited and the ocean becomes very deep close to the Kenyan coast. There is no information on the deeper benthic ecosystems near the coast and also with respect to the pelagic domain only limited information is available: so far it appears that these areas combine a low productivity with a high diversity. In the North, the Somalistream causes strong upwelling during summer. The interactions between the off-shore and coastal areas and the impact of the monsoon on these interactions are unknown. The sedimentology of the East-African coastal zone is unknown as well. The coastal ecosystems in Kenya consist of: (1) coral reefs (fringing reefs) along the entire coastline, with extensive areas of seagrass beds on the more sheltered parts of the backreefs and in lagoonal areas; (2) mangroves on the shores of the brackish parts of rivers and creeks along the coast; also seagrass beds can be found here.Pages
