Some Critical and Methodological Aspects of Shoreline Determination: Examples from the Baltic Sea Region

摘要

Coastal shorelines worldwide are generally unstable and changing. The study of the precise relation between any archaeological site and the shoreline at the time when the site was used is therefore complicated, but still often not met with appropriate methodological approaches. In this article, we test models based on phosphate analysis and discuss how they can be used to detect ancient shorelines. We propose that a model of increased and oscillating phosphate values at the former water level is considered reliable and useful in areas with advancing shoreline.
