SOUTHAMPTON, ENGLAND—Quartz.com reports that the Black Sea Maritime Archaeology Project found more than 40 Byzantine and Ottoman shipwrecks during geophysical surveys of the Black Sea seabed along the Bulgarian coast. Many of the hulls, masts, tillers, and other features of the ships are well preserved, due to the low oxygen levels in the deep waters. Principal investigator and University of Southampton marine archaeologist Jon Adams and his team of researchers recorded information about the ships with laser scanners, and they took thousands of high-resolution photographs and videos of the shipwrecks with remotely operated vehicles. The images were then assembled with photogrammetry to build 3-D models of the shipwrecks.
