ATHENS (Reuters) - Hidden and protected for millennia, an ancient shipwreck in Greece opens to the public for the first time on Aug. 3, fusing archaeological wonders in the depths of the sea with the marvels of modern-day artificial intelligence.

Access to underwater sites is typically restricted in Greece to preserve their integrity. But authorities have been able to allow recreational diving at the shipwreck at Peristera, thanks to computer surveillance technology.
