Isotopic studies of the diet of the people of the coast of British Columbia.

In 1982, Chisholm et al. used δ(13) C data for human burials from shell midden sites widely distributed on the coast of British Columbia (BC) to show the extreme dependence of these individuals on high trophic level marine consumers, principally salmon and marine mammals. Here, we present previously unpublished analyses of δ(15) N for some of the same individuals as well as δ(13) C data for additional individuals.
