Data for salmon and plants for δ13C and δ15N are taken from Mowat and Heard (2006); endpoints for δ34S and generalized meat are derived from data from this study.

Raw data obtained from stable isotope analysis of δ 13 C and δ 15 N in beaks of the Arctic squid, Gonatus fabricii (Lichtenstein, 1818) (Cephalopoda: Oegop
δ13C values of modern specimens were corrected by +1.5 ‰ for the Suess effect [108]. Proportion of C4 (%) in the diet was reconstructed using mean estimated δ13C values of pure-C3 and pure-C4 feeders.
