The submarine was found elsewhere, but soon it became clear that there was no O-13. "We measured it and saw it from things like length or where there was a gun that could not be him."
It's also difficult to figure out which submarine is. "Such a war wreck has grown completely after 70 years under water, where you can find a sign or a cup with a name. Some of these boats had their own office or window with a number."
In addition, it is not certain that the ship is at the level of diving. "In Norway, the sea is sometimes 600 meters deep, because there is hardly anything you can find with sonar there." The ship's expedition has unmanned diving boats, but this does not show everything properly.
Free crustaceans and lobsters
It's not about the expedition that brought nothing. The main goal of the Dive North Sea Clean Foundation is to remove seabed nets, for example from shipwrecks. Plastic from the nets is dangerous for marine life. "We betrayed hundreds of crabs and lobsters."
