AbstractAbstract
[en] A 200 year old brain coral, captured in Bermuda in 1976 was slabbed and x-rayed. Using the annual growth bands sequential, dated samples were taken over the entire growth period of the coral and analyzed for Δ14C, sigma13C and delta18O. During the past 80 years atmospheric variations in Δ14C and delta13C due to human effects, such as release of bomb C-14 and dilution of both C-14 and C-13 by fossil fuel burning, are closely tracked by the coral. Prior to 1900 divergences between the coral and tree Δ14C and delta13C can be related to world-wide changes in plant production and possibly oceanic upwelling rates
