A Greek shipwreck photographed.

Sometime in the fourth century B.C., a Greek merchant ship sank off Chios and the Oinoussai islands in the eastern Aegean Sea. The wooden vessel may have succumbed to a storm or a fire, or maybe rough weather caused the cargo of 400 ceramic jars filled with wine and olive oil to shift without warning. The ship went down in 60 meters (about 200 feet) of water, where it remained unnoticed for centuries.

The classical-era ship might never have divulged to archaeologists its clues to ancient Greek culture, except for a research team from MIT, the Woods Hole Oceanographic Institute (WHOI), the Greek Ministry of Culture and the Hellenic Centre for Marine Research (HCMR). They used a novel autonomous underwater vehicle (AUV) to make a high-precision photometric survey of the site last July. Using techniques perfected by MIT and WHOI researchers over the past eight years, the robot accomplished in two days what would have taken divers years of effort.

Sadly, the robot did not answer the most important question: was the wine still any good?
