Ancient Greek shipwreck in Black Sea

An ROV was used in the discovery and survey of a Greek trading ship, dated 400BC, making it the oldest intact shipwreck known to man. The shipwreck is incredibly well-preserved due to the anoxic (lacking oxygen) conditions at depths below 60m in the Black Sea.

The vessel, 75-foot-long Greek trading ship designed with both sail and oar-power, is very similar to the one Odysseus sailed during his encounter with the Sirens, returning from the Trojan War.
