| Description | Consumption of marine protein in humans and animals can result in an apparent older radiocarbon $(^{14}$C) age due to reservoir offsets. In order to correct for this, an estimate of the marine protein intake should be used to correct the$ ^{14}$C age for reservoir offsets, which is ordinarily done using $δ^{13}$C or $δ^{15}$N values. However, these two isotopic proxies can be influenced by a number of factors which can hamper estimation of the correct marine protein intake. A small dataset of 12 samples from the Limfjord, Denmark, ranging in age from Mesolithic to Viking Age, was used to test the use of $δ^{2}$H values to quantify marine protein intake and determine the reservoir corrections. Each of the three stable isotopic values $(δ^{2}$H, $δ^{13}$C, $δ^{15}$N) was used to estimate the percent marine protein intake, which produced three different calibrated$ ^{14}$C ages. The calculated percent marine protein intake differed between the use of the stable isotopic ratios with a maximum difference of 42.1% between the use of $δ^{15}$N and $δ^{13}$C, 23.8% between $δ^{2}$H and $δ^{13}$C, and 46.2% between $δ^{2}$H and $δ^{15}$N. In some cases the calculated percent marine protein intake changed the sample’s archaeological period, although there was generally still overlap in the archaeological periods for samples used in this study. |
