A tantalizingly brief item from Divernet:

Archaeologists are reported to have examined a 4th century BC wooden merchantman in the eastern Aegean.

The wreck was discovered in 2004 during a sonar survey near the islands of Chios and Oinoussia. February's two-day survey, a joint exercise by Greek and American experts, was carried out by ROV and sonar to build up detailed photographic and computerised images.

The wreck lies at around the air-diving limit, at 61m.
