At present, too few measurements of 14C in the atmosphere exist to explicitly test the model prediction shown in the figure left.We have calculated isotope shifts for several one- and two-photon transitions in neutral carbon.Changes in atmospheric CO clearly must be explained by repartitioning of carbon among these three reservoirs.However, scientists do not yet fully understand the fundamental processes controlling this carbon “cycle”.The results provide a unified interpretation of existing experimental data, and they demonstrate the applicability of a new method of ultrasensitive isotope trace analysis to carbon.© 1983 Optical Society of America Full Article | PDF Article You do not have subscription access to this journal.When listening to this CD set, you need to remember that the evolutionary scientists control the majority of peer review publications, science journals, laboratories and museums.Consequently, the scientific information accepted for print in school textbooks and media news reports comes from these sources.

In 2001, ESS/CGECR researchers Ellen Druffel, John Southon and Susan Trumbore were awarded million by the W. Keck Foundation for the development of an accelerator mass spectrometry (AMS) facility – the Keck-Carbon Cycle AMS facility – for radiocarbon measurements in support of carbon cycle research at University of California, Irvine.

The predominance of 14C-depleted air in the northern hemisphere is the result of burning of fossil fuels, which contian zero radiocarbon.

An atmosheric measurement program to test these predictions would be useful in reducing uncertainty about the present sources and sinks of carbon dioxide.
