This discussion of the isotopic analyses of human samples from Greenland begins with a review of the colonization of the island and a description of the sites and the samples that were collected for analysis. In addition, a brief consideration of the geology and bioavailable ⁸⁷Sr/⁸⁶Sr is provided. The analysis of the human data from Greenland follows an introduction to the variation present and observable differences between the Eastern and Western Settlements. Specific sites on Greenland are discussed in some detail in terms of the isotopic data that is available. A summary of dietary and mobility estimates is provided. Non-local individuals are identified and in some cases suggestions of place of origin are made. It is important to remember that Greenland was settled later than Iceland and all the Norse graves are from the Christian period, meaning burial in churchyards with few if any grave goods.
