Case studies on conventional munitions
(The sea mines need to be further studied to determine a safe and cost-efficient disposal procedure for each of their types. DAIMON will examine two locations of known dumped conventional munitions: in Gulf of Finland and in German coastal waters (Kiel Bight) (12smz and parts of EEZ)
Caging experiment in the Gulf of Finland
Blue mussel is suitable for caging experiments as it filters large amounts of water, accumulates many types of contaminants, and is relatively tolerant to pollution. Caging of mussels has been widely used as a bioeffect monitoring and assessment method in marine environments. It has also been demonstrated to be a useful tool in coastal environment of the northern Baltic Sea as well. This is why caging was selected for the priority method in the Gulf of Finland, where one cage was deployed close to a suspected contamination point (large sea mine lying on the seafloor). Two other cages were references, and were placed on a clean area, 1nm and 2nm from the “hot-spot” cage. Aim of the experiment was to investigate if the sea mine is leaking TNT or other toxic substances, and if any biological effects or bioaccumulation can be seen in the mussels, which were anchored close to the mine.
