Arguably, few research topics engage so many different fields of science and have such a profound impact on our understanding of Earth and Solar science as the history of C in the Earth's atmosphere and the surface and deep oceans.
I read the scientific article on the carbon dating done on the Jericho site written by Bruins and Van Der Plicht.
When I did the math from their results section of the YBP, they all turned out to be right around the year 1400 .
The difference of the two curves (R) is ~400 yr on average.
Details An example of bomb-pulse radiocarbon dating of a terrestrial sample from Northern Hemisphere zone 1.
Mortlock, Tzu-Chien Chiu, Li Cao, Alexey Kaplan, Thomas P. Any opinions, findings and conclusions or recomendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation (NSF).In our laboratory, we have overlapped and extended the tree-ring radiocarbon calibration from 3,000 to 55,000 yrs.BP using coral samples from our offshore coral reef core collections from Barbados (13.10°N; 59.32°W) in the western tropical Atlantic and Kiritimati Atoll (1.99°N, 157.78°W) in the central equatorial Pacific, and from the uplifted reefs of Araki Island (15.63°S; 166.93°E) in the western Pacific.For the remaining period 12,400-26,000 cal yr BP, the curve is derived from independently dated marine samples such as foraminifera and corals.A new internationally-ratified calibration curve (Int Cal09) covering the whole radiocarbon timescale (~50,000 cal yr) is being prepared by the Int Cal Working Group.
The result is that radiocarbon and calendar ages are not identical, and the radiocarbon ages have to be converted to calendar ages using a calibration curve, which describes the atmospheric C concentration in the past measured in precisely and independently dated materials.
