Carbon-14 Measurements in Atmospheric CO2 from Northern and Southern Hemisphere Sites, 1962-1993
- Norges Skipsforskningsinstitutt, Trondheim (Norway)
In the 1960s, thermonulcear bomb test released significant pulses of radioactive carbon 14 into the atmosphere. This major perturbation allowed scientist to study the dynamics of the global carbon cycle by measuring and observing rates isotopic exchange. The Radiological Dating Laboratory at the Norwegian Institute to Technology performed carbon 14 measurements in atmospheric carbon dioxide from 1962 until 1993 at a network of ground stations in the Northern and Southern hemispheres. These measurements were supplemented during 1965 with high- altitude samples collected using aircraft from the Norwegian Air Force. The resulting database, coupled with other carbon 14 measurements, broad spatial coverage of sampling, consistency of sampling method, and the change in carbon 14 calculation results corrected for isotopic fractionation and radioactive decay. This database replaces previous versions published by the authors and the Radiological Dating Laboratory.
