Эпизод 2

There is a sea more mysterious than all others combined. This is where history set sail and never made it to port - and now, centuries later, lies perfectly preserved in poison. The Black Sea is a treasure trove of sunken ships - lying frozen in time -- and marine archaeologists have barely scratched the surface of what might be uncovered beneath its lifeless waters. That is why world-renowned marine geologist Robert Ballard is revisiting this enigmatic sea. How is it possible that a 1,500-year-old shipwreck is in near perfect condition, looking as if it sank just yesterday? And what secrets does it hold?
