  2. Objectives • To provide new physical and biogeochemical data and to extend existing continuous • measurements of selected parameters and processes defining the basic structure of • shelf ecosystems and straits, to characterize the forcing, and to analyze the contemporary • states and temporal changes of these systems. • To determine life cycle and growth rates of zooplankton target species required in the • pelagic ecosystem models an estimate of the vertical flux of elements in the upper water column. • To analyze the response of shelf ecosystems, in terms of function, biodiversity and • food web structure, to river runoff, mixing / circulation and exchanges with the deep sea. • To investigate water masses exchange and transport of materials and the interactions • within the pelagic food web (phytoplankton, bacteria, nano-flagellates, micro • and meso-zooplankton) and the environmental components controlling their dynamics • along the gradient zone of the straits. • To determine mechanisms for cycling, export and sequestration of carbon at sub-basin scale, • with respect to air-sea CO2 exchange, organic carbon fluxes (production, degradation • and export) and atmospheric inputs of nitrogen and phosphorus.

  7. Continental Shelf Pump The continental shelf pump is a mechanism transporting dissolved or particulate carbon from shallow continental shelf waters to the interior of the adjacent deep ocean. * cooling / convection restricted to the shallow continental shelf leads to the production of relatively denser water on the shelf compared to neighbouring open ocean * the cooler waters promote the solubility pump and lead to an increased storage of dissolved inorganic carbon * this extra carbon storage is augmented by the increased biological production characteristic of shelves (e.g. Wollast, 1998) * the dense, carbon-rich shelf waters sink to the shelf floor and enter the sub-surface layer of the open ocean via isopycnal mixing

  8. Compare catchment areas of Mediterranean and Black Seas: Mediterranean: north side: very narrow, but mountain sources abundant, south side: even narrower and dryer, with the exception of the Nile, which is now intercepted by Aswan high dam. Black Sea: large catchment, with major rivers such as the Danube draining about one half of Europe. SIGNIFICANT MODIFICATIONS MAY BE EXPECTED ACCORDING TO CLIMATE CHANGE SCENARIOS: north becoming wetter, south becoming dryer. Thickness of lines show relative size of river discharge

  36. Problems: • - carbon sequestration studies - eastern med covered by both atmospheric and ocean measurements western mediterranean - how to integrate existing (?) measurements ? - wp3 organised on ‘voluntary’ basis as each region is separate in their specifics, and it is assumed each partner knows its region best - integration with other WP’s especially between WP3 and WP4/5/6, but also with WP1/2 - to get timely information from partners on plans, problems, results - integration of individual studies together to make a whole
