14C Calibration in the 2nd and 1st Millennia BC—Eastern Mediterranean Radiocarbon Comparison Project (EMRCP)
Open accessAbstract
We have measured additional known-age German oak samples in 4 intervals in the 2nd and 1st millennia BC to add to (and to replicate) parts of the international Northern Hemisphere radiocarbon calibration data set. In the 17th, 16th, and 12th centuries BC, our results agree well with IntCal04. In the 14th and 13th centuries BC, however, we observe a significant offset, with our results on average 27 yr older than IntCal04. The previously reported 14 C offset between Anatolian juniper trees and central European oaks in the 9th and 8th centuries BC is smaller now, on the basis of our new measurements of German oak, but still evident. In the 17th and 16th centuries BC, the 14 C ages from the Anatolian chronology agree well with IntCal04 and our new German oak data.

The GOR time series was compared with IntCal98 and IntCal04 specifically because they do not include subsequent Hd GeO data, avoiding circularity.
“We compare our data with these two records specifically because they do not include subsequent Hd GeO data (38), avoiding circularity.”
From Mediterranean radiocarbon offsets and calendar dates for prehistory (2020) · cites this paper as [38]
The Introduction (page unavailable) says the Anatolian tree-ring series was compared with IntCal98 and IntCal04. But Tree-Ring Series and Methods says earlier Heidelberg German-oak measurements were already part of IntCal04, and the paper does not give avoidance of circularity as the reason for choosing those curves. The claim’s blanket statement that both curves exclude the relevant Hd GeO data is therefore not supported. (LLM, conf=0.87)
Experimental — accuracy not yet measuredWe would have anticipated that the AA data on BCP and IrO should be similar to the IntCal datasets and the Hd GeO data, given the good agreement in other recent work between GeO and BCP and between GeO and IrO.
“We would therefore have anticipated that the AA data on BCP and IrO (13) should be similar to the IntCal datasets (1–4) and the Hd GeO data (38), given the good agreement in other recent work between GeO and BCP (40–42) and between GeO and IrO (1–4).”
From Mediterranean radiocarbon offsets and calendar dates for prehistory (2020) · cites this paper as [38]
The citation is attached to the reported agreement between GeO and BCP. The Results and Discussion compare German oak with IntCal04 and Irish oak, but our copy does not report a GeO–BCP comparison; searches for BCP and bristlecone pine found none. Those other comparisons cannot establish the specific agreement attributed to this source. (LLM, conf=0.73)

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.
