After WW2 over 32,000 tons of Received in revised form 22 April 2010 chemical war material was dumped here including shells and bombs as well as small drums and containers. Accepted 29 April 2010 The geophysical investigations combined very-high-resolution seismics and gradiometric measurements. Available online xxxx The results indicate the presence of a large number of objects buried just below the seafloor. The size of the objects and their distribution, with a marked increase in density towards the center of the dumpsite, Keywords: Chemical munition dumpsite suggests that we are dealing with dumped war material. Sediment and near-bottom water samples, taken Baltic Sea within the dumpsite and in the surrounding area, were analysed for the presence of various chemical Chemical analysis warfare agents (CWA) including Adamsite, Clark, sulphur mustard, tabun, chlorobenzene and arsine oil.
