Integrated geoarchaeological methods for the determination of site activity areas : A study of a Viking Age house in Reykjavik, Iceland

Acknowledgements The excavation was funded by the City of Reykjavík, and the geoarchaeological research was funded by a SSHRCC Doctoral Fellowship from the government of Canada, an Overseas Research Studentship, the Cambridge Commonwealth Trust, Pelham Roberts and Muriel Onslow Research Studentships from Newnham College, Cambridge, and Canadian Centennial Scholarships from the Canadian High Commission in London. Garðar Guðmundsson took the micromorphology samples, and supervised sampling on site. The bones were counted by Clayton Tinsley, the thin sections were made by Julie Boreham, and Steve Boreham and his team in the Department of Geography, University of Cambridge, provided technical support for all of the bulk geochemical analyses that were conducted by K. Milek, except for ICP–AES, which was conducted by ALS Chemex. Our gratitude is extended to Charles French, Catherine Hills, Peter Jordan and two anonymous reviewers for their support and helpful comments on earlier drafts of this paper, and to Óskar Gísli Sveinbjarnarson for his assistance with the figures.
