The reference to the Titanic concerns the fairly widespread publicity given to the apparent removal of objects from the wreck as ''finders keepers'' and their alleged offer for sale on internet auction sites. The concern is that the same could happen with the wreck of Bismarck or any other sunken ship in the future.
I am all in favour of exploring the debris field, on a look but don't touch basis, ie. without looting. But until international law is clarified on this the motives of future expeditions inevitably comes into question. This is particulary so if proposals arise to refloat the wreck, as I believe have been made with respect to Titanic.
