Description: 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.
