Chlorofluorocarbons and noble gas measured on water bottle samples during POLARSTERN cruise ANT-XXIV/3 ...
During the cruise a total of 1620 samples on 97 CTD/water bottle stations were collected for chlorofluorocarbons (CFC-11 and CFC-12); 32 stations were occupied along the Greenwich Meridian section, 37 stations along the Weddell Sea section, and 28 stations across the Drake Passage. The water samples...
