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: Kreservoir = 410 * (19.8 + δ13Csample)/8. 9 14C − years (Rasmussen et al., 2008 [47]).
