This research stream focuses on archaeological materials and the application of strontium isotope analysis. The aim is to determine, through the analysis of burned animal bones, where seals were hunted. The project will also explore the significance of seal hunting for prehistoric communities. The research combines scientific and humanities-based approaches. This research stream seeks to determine the strontium isotope signatures in various regions of the Baltic Sea and Finland's largest lakes and create baseline (isoscape) for the future studies. The project will also investigate whether large-scale temporal variation exists in strontium isotope compositions in major lake systems in the past. This research is primarily natural science-oriented.
