Ocean margin exchange II - Phase II

Description: Das Projekt "Ocean margin exchange II - Phase II" wird vom Umweltbundesamt gefördert und von Universität Kiel, GEOMAR Forschungszentrum fur marine Geowissenschaften, Abteilung Marine Umweltgeologie durchgeführt. General Information: The main objectives of OMEX II-II are the construction and understanding of the carbon cycle and its associated elements along the Iberian coast. This area is dominated by wind driven up welling events during the summer and by ria inputs and down welling during the winter. Coastal up welling areas are among the most productive biological systems in the ocean and therefore of particular economical interest. They are also characterized by large fluxes of organic carbon, nutrients and other trace elements which may be exported to the open ocean or rapidly deposited and buried at geological time scales. They are thus playing an essential role in the marine biogeochemical cycle of many elements. The study of the physical processes should provide knowledge of the local factors (wind and topography) affecting horizontal and vertical transport in relation to the general circulation. Special attention will be devoted to the role of filaments and eddies in the exchange of material between the coastal zone and the open ocean. Short time scale measurements of flows of carbon and nutrients through the food web will be performed during up welling events and occasionally in the winter during periods of down welling. On the other hand, spatial and seasonal variations of the inventories and fluxes of the carbon and associated elements will be investigated to obtain mass balances and to develop models of dynamic processes occurring in the water column. Since a large part of the primary production in the coastal up welling zones is rapidly deposited, a special attention will be paid to the understanding, quantification and modelling of the benthic processes related to biological activity and early diagenesis. A better knowledge of the carbon fluxes and budgets will improve our evaluation of the role of up welling in organic carbon production and fate in the marine system. This study may refine our understanding of the effect of coastal up welling on the global climate control and vice versa of potential effects of global warming on the up welling processes.
