WOCE IV: Tracer

Description: Das Projekt "WOCE IV: Tracer" wird vom Umweltbundesamt gefördert und von Universität Kiel, Institut für Meereskunde, Abteilung Regionale Ozeanographie durchgeführt. During the past several decades, the atmosphere and the upper ocean have been tagged with Chlorofluorocarbons (CFCs, components CFC-11, CFC-12) that had previously not existed in the environment. The CFCs are introduced into the deep ocean in regions of deep convection (reaching well below l000 m depth) like the Labrador Sea, the Greenland Sea, and the Western Mediterranean. Another mechanism is the sinking of CFC-rich water after overflowing a sill, for instance at the Denmark Strait between Greenland and Iceland. Since die CFC concentrations in atmosphere and upper ocean increased with time, one expects to find a temporal increase in die deep water as well. Studying the temporal evolution of die CFC distribution provides a means to estimate: - production rates of deep water, - the spreading paths of deep water, - the time scales of spreding, - the variability of water masses.
