Description
Summary:This thesis deal with three individual Pagophilus groenlandicus canin teeth from the location Asva, Estonia dating from the Late Bronze Age (here 700-900 B.C). The aim of this thesis is to find out whether the three harp seal individual was local or non-local to Asva and further if they were migrants from the Atlantic Sea. The teeth enamel are analysed for strontium isotopes using LA-ICP-MS and the result was compared against the strontium 87Sr/86Sr values in various rivers in the Baltic Sea. This is to see how the harp seal has migrated around in the Baltic Sea. By placing the 87Sr/86Sr values against the rivers, it may seem that the three harp seals were non-local and not from the Atlantic Sea.
