Ancient ship discovered intact
Ancient ship discovered intact A 1,500 year old wooden ship has been discovered
in the Black Sea off the coast of Turkey. The unique oxygen-free
environment in the deep water of the Black Sea has allowed the ship
to be preserved so well, that it looks like a modern ship. Unlike
other oceans, the deep water of the Black Sea does not circulate,
and therefore contains no oxygen. This oxygen-free environment is
perfect for preserving artifacts. NOVEMBER 4, 2000
