The team took thousands of still photographs of the shipwrecks, and then used photogrammetry, a technique that uses software to calculate the positions of millions of points in space, to build 3D models of the discoveries.

Some of the ships discovered are thousands of years old, dating to the Byzantine empire, while others are from the Ottoman period.
Hulls, masts, tillers, and rudders are all clearly discernible. “Certainly no one has achieved models of this completeness on shipwrecks at these depths,” said Adams.
