Danish researchers have found three well-preserved shipwrecks in the Baltic Sea that are estimated to be more than 300 years old. Two of the ships are almost certainly Dutch cargo ships, the Sea War Museum in Thyborøn, Jutland, reported on Wednesday. The third and largest is probably Scandinavian. All three ships were found at a depth of about 150 meters.
"It was fantastic to see the ships on the screen as we sent an underwater robot with a camera down to the seabed," said expedition leader and museum director Gert Normann Andersen, according to the release. "The ships looked like they had just been abandoned."
In contrast to the North Sea, where all wrecks disintegrate in record time, many ships in the Baltic Sea are well preserved. This is due to the fact that neither shipworms nor other wood-boring animals can live in the Baltic Sea at such a depth where the soil environment is acidic and low in oxygen.
