Seal Bones from the Beach Ridges: Isotopic Values of Cape Krusentern Achaeofauna
Strathe C. 2007. Seal Bones from the Beach Ridges: Isotopic Values of Cape Krusentern Achaeofauna
Seal bones associated with datable material were collected during the 2006 surveys at Cape Krusenstern for stable carbon and nitrogen isotope analysis. The examination of isotopic data from these archaeologically deposited seal remains providesa view of cultural and ecological change at large temporal scales. Datable material and seal bone samples were collected from shovel tests on beach ridges. These stable carbon and nitrogen values and associated radiocarbon dates have been usedin reconstructing temporal changes in Chukchi and Bering Sea marine ecosystem productivity from approximately 2000 B.P. to present. This preliminary proxy of ecosystem change can then be compared to changes in cultural systems at Cape Krusenstern to test for possible causation.
