A 200 year record of carbon‐13 and carbon‐14 variations in a Bermuda coral
Abstract
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 Δ 14 C, δ 13 C and δ 18 O. During the past 80 years atmospheric variations in Δ 14 C and δ 13 C 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 Δ 14 C and δ 13 C can be related to world‐wide changes in plant production and possibly oceanic upwelling rates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
