Underwater
There are some 300 possible ship wreck sites recorded off the coast, either as net snags or documentary records, with only an accurate location for twelve of these.
Although some of these sites are protected most are not and are still awaiting detailed excavation and description. User pressure in the form of vandalism and in the case of underwater site salvage may cause loss and damage of important sites. Environmental impacts from coastal erosion may lose finds before their significance is assessed.
