Transect along 24oN Latitude of 14C in Dissolved Inorganic Carbon in the Subtropical North Atlantic Ocean
The distribution of bomb-produced 14C in the ocean provides a powerful constraint for circulation models of upper ocean mixing. We report 14C measurements from an east-west section of the main thermocline at 24oN latitude in the subtropical North Atlantic Ocean in summer 1992, and one profile from t...
