Abstract

Very high resolution seismic and magnetic investigations were carried out over a chemical munition dumpsite in the south-western Baltic Sea. The shallow geology was imaged in great detail on the seismic data and seven seismic-stratigraphic units were identified, related to different stages in the Holocene and late-glacial history. A large number of diapir-like features were observed that most likely represent fluid expulsion phenomena. Seismic and magnetic data indicate the presence of a large number of buried objects. In most cases there is a good correlation between the two data sets. The objects are buried no deeper than 1-2 m. Their size varies between 1.5 and 5 m, occasionally up to 10 m. The data confirm the wide variety of dumped war material ranging from bombs and shells to encasements and containers. The distribution of the buried objects seems heterogeneous with locally high object concentrations surrounded by areas of lower object density. The results of this case study demonstrate the benefit of complementary, concurrent geophysical investigations for munition dumpsite research. This will yield a better assessment of the current status of the dumpsite and possible ecological risks related to the dumped war material.
