Radiocarbon Anomalies from Old CO2 in the Soil and Canopy Air
Open accessAbstract
The canopies of forests and cultivated fields can retard the ventilation of CO 2 respired from the soil. The plants in dense canopies can then acquire a small fraction of their carbon by recycling some of the respired CO 2. Furthermore, some plants can assimilate a small fraction of their carbon by uptake of CO 2 in the soil via their roots. In tectonically active areas, the diffuse flux of CO 2 from geological sources may be comparable to that from normal soil respiration. In such areas, both the canopy and root uptake effects may allow plants to acquire a measurable fraction of their carbon from geological sources. Because this “old” carbon lacks radiocarbon, its assimilation would increase the apparent 14 C ages of the plants. These effects may account for some of the discrepancies between archaeological and 14 C dates.

A reappraisal of the Akrotiri volcanic destruction level 14C data set from short-lived samples, in light of Soter (2011), suggests that a dating for the Santorini volcanic eruption in the late 17th century BC remains most likely, in particular somewhere in the last 3 decades of the 17th century BC.
“In conclusion, a reappraisal of the Akrotiri volcanic destruction level 14 C data set from short-lived samples, in light of the paper of Soter (2011), suggests that a dating for the Santorini volcanic eruption in the late 17th century BC remains most likely: in particular somewhere in the last 3 decades of the 17th century BC.”

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.
