Matt Skelhorn, wreck researcher at the MOD, has kindly offered to give another presentation at the college on the work they are doing in Scapa Flow. This involves determining the rates at which the wrecks are corroding. The wrecks they will be working on are HMS Royal Oak, HMS Vanguard, SS Juniata, SMS Kronprinz Wilhelm and SMS Karlsruhe. The information will be used as a guide to the rates at which other MOD owned legacy wrecks are decaying and act as a precursor to a wider survey of such vessels.
