The dead are believed to persist in the waters of the Black Sea. Remains of ships and humans and other decomposable materials like ropes, wood etc. can still be found at the seabed, hundreds of years after their entry into the waters of the Black Sea. The scientific explanation for it is that due to the anoxic nature of the lower water layers of this sea, the process of decomposition is negligibly slow, hence, the persistence of remains of the dead inside the sea's water.
