The Black Sea has long been important to the powerful empires which have occupied the region.

The researchers are studying changes in water levels and the effects on ancient humans in the area.

Discovering the wrecked vessels was incidental to their main mission.

However, the archeologists have fully embraced what the sunken ships can tell us.

Using remote-operated vehicles (ROVs), the team has explored the wrecks.

The detail captured is remarkable and shows things like masts, bows, and engraved decorative wood.

The teams have surveyed about 60 wrecks and discovered vessels that are Roman, Byzantine, and Ottoman.

How have these wrecks survived in such good condition?

The answer to their incredible preservation lies in the chemistry of the Black Sea.

At about 500 feet deep, the water becomes anoxic or deficient in oxygen.

It is also very low light.

This is not conducive to the sort of sea life which would normally feed on sunken wood ships.

Black Sea MAP is bringing its amazing discoveries to the wider world.

Involving advisory schoolchildren in the research, the team has created educational resources for children and teens.
