Baltic Sea Lübeck Bay, ammunition boxes under water
One option for dealing with munitions in the sea is to tolerate the contamination, if necessary by accepting restrictions on the use of contaminated areas or prohibitions on access. Relocation within a marine area (from a Traffic Separation Scheme to a hot-spot) to mitigating direct risks at the site of concern is also considered as "leaving in place".
However, a condition of this approach should be the observation of the development at appropriate intervals (monitoring).
