^aThe archaeological date is based on a chronology of different arm positions used during the Southern Scandinavian Middle Ages [24, 44].
^bEstimation of % marine diet is based on linear interpolation with an endpoint of −10.9 ‰ (assuming a 100% marine diet) and an endpoint of −19.8‰ assuming a 100% terrestrial diet [50].
^cThe following formula was used to calculate marine reservoir correction: K_reservoir = 410 * (19.8 + δ¹³C_sample)/8. 9 ¹⁴C − years (Rasmussen et al., 2008 [47]).
