Characterizing the error in the estimated age-depth relationship.
Abstract
It is common practice to estimate the age of undated material extracted from a sediment core from radiocarbon or other radiometric dates of samples taken above and below the extracted material. This paper presents a simple expression for the variance of this estimated age. This variance accounts for both (super 14) C dating error and error due to bioturbation.
