High productivity and fast turnover rates of nutrients and organic and inorganic matter characterize the shelf seas. Both, high fishery effort as well as other anthropogenic influences including the elevated CO2 input affects the regions significantly. Climatic change with altered gas budgets, shift of ocean currents, and the considerable warming of sea water visibly and rapidly impact the conditions of life and production in the shelf seas, as well as the adjoining coasts. To assess the effects of global change, it is necessary to record the regional status quo situation and to develop and apply adequate means for prognosis. The ClimShelf project will investigate the dynamics of material flux in the shelf sea area of the poly-pulsed Benguela Upwelling system, including the exchange with the open ocean. Combined with existing data from local long-term series and previous cruises, modelling approaches will be developed to forecast the ecological effects of climate change. The expedition is planned as the third field phase of the running RTD-project GENUS (Geochemistry and Ecology of the Namibian Upwelling System) of the German Ministry of Education and Research (BMBF) under the international umbrella of IMBER (Integrated Marine Biogeochemistry and Ecosystems Research).
