Exploring the Black Sea with robotic submersibles. The Black Sea is the largest body of anoxic water in the world. A remarkable thing happens in such waters: wood, cloth, food, and other organic materials do not decay and disappear — ships that went to the bottom hundreds or thousands of years ago still rest on the seafloor in almost the same condition as when they sailed the surface. The trick is getting down into the depths to find them.
