Pulses of Rapid Ventilation in the North Atlantic Surface Ocean During the Past Century
The Suess Effect is a gradual decrease of the 14C/12C ratio in tree rings from 1870 to 1950 that is attributed mostly to the burning of 14C- free fossil fuels for energy. In contrast, pre-nuclear bomb high-precision measurements of 14C/12C ratios in banded corals from the North Atlantic Ocean do not...
