Over the past twenty years there has been a significant increase in
underwater activities such as scuba diving which, coupled with the
adventure andromance always associated with shipwrecks, has led to
rapid developments in the discovery and excavation of shipwrecked
material. These shipwrecks are invaluable archaeological 'time
capsules', which in themajoriety of cases have come to an equilibrium
with their environment. As soon as artefacts on the wreck site are
moved, this equilibrium is disturbed, and the artefacts may commence
to deteriorate, sometimes in a rapid and devastating fashion. In fact
excavation without having conservation facilities available is
vandalism--the artefacts are much safer being left on the sea bed.
Such famous shipwrecks as the Mary Rose (1545), the Wasa (1628) and
the Batabia (1629) have not only brought the world's attention to
these unique finds, but have also produced tremendous conservation
problems. The treatment of a 30 metre waterlogged wooden hull or large
cast iron cannon is still causing headaches to conservators.
