The vertical axis shows depth below modern sea level; the horizontal axis shows calibrated years before AD. To produce a curve that can be used to relate calendar years to radiocarbon years, a sequence of securely dated samples is needed which can be tested to determine their radiocarbon age. Correcting for isotopic fractionation, as is done for all radiocarbon dates to allow comparison between results from different parts of the biosphere, gives an apparent age of about years for ocean surface water. Willis, E. Aitken, M. For example, there was a plateau between around and BCE, which makes radiocarbon dates less accurate for samples dating to this period.
