Abstract

This paper is concerned with the expected deviations in the production rate of natural14C on the earth due to changes in solar activity. We review the published estimates of the global production rates of14C due to galactic and solar cosmic ray particles, and present new estimates of the expected secular variations in14C production, taking into account the latest information available on galactic cosmic ray modulation and long-term variations in solar activity.

The Radiocarbon Record in Tree Rings of the Last 8000 Years

Hans Suess (1980)

It has become generally accepted during the last year that 14C fluctuations, the so-called “wiggles”, observed in wood, dated by its tree rings, do indeed exist. Furthermore the La Jolla measurements show that apart from experimental noise, they do not represent random red noise, but characteristic, recurring features. In 1971, Houtermans found indications for the existence of cyclic components and recent Fourier analyses of all the available data by Neftel and Hartwig show a 200-year component. Cyclic oscillations with other periods appear to be present during limited time intervals. The character of the oscillations is not harmonic. The time derivative of many fluctuations is remarkably constant and such that the 14C rises by 1 percent in about 20 years and decreases by 1 percent in slightly more than twice that length of time. The properties of the overall radiocarbon record have to be considered in attempts to explain the variations in terms of variations of the cosmic ray-production rate and changes of the geochemical distribution of radiocarbon.
