Short summary
We present a 60-year record of radiocarbon in carbon dioxide (14CO2) from Wellington New Zealand. It records the atmospheric 14C “bomb spike” and decline as bomb 14C moved through the carbon cycle and fossil fuel emissions increased. The bomb peak is lower and 1.4 years later than in the Northern Hemisphere. Since the early 2000s, Wellington 14CO2 has been elevated above the Northern Hemisphere, possibly due to a reinvigorated Southern Ocean carbon sink.
