Physical oceanography and CFC measured on water bottle samples during METEOR cruise M53/3 ...
Repeated observations of CFC-11 and CFC-12 in the western tropical Atlantic over the period from 1990 to 2002 are used to fit parameters of the age spectra for several North Atlantic Deep Water components: the upper Labrador Sea water (ULSW), the Labrador Sea water (LSW), and the lower North Atlanti...
