I don't. It sounds as if I'm running away from the issue, but for us at DHH, the issue is really the identification of human remains when there is a report of a finding and when those human remains can't remain where they are. We know where ships have been lost; I could come back to you with the total number.
Our interest has been what happens when a wreck becomes so easily accessible that the kind of sacrosanct nature of a wreck, even declared as a war grave, begins to get doubtful. In the Nomad case, it had lain in Lake Muskoka for about 50 years. Then the zebra mussels did their work and cleared the waters, and it was seen. Had it been declared a war grave at some point in the past when it wasn't seen, I don't think we would have faced the problem that we did once the zebra mussels did their work and the waters cleared.
