The Swedish team of treasure hunters "Ocean Explorer" found by sonar on the bottom of the Gulf of Bothnia the strange round object, about several dozen meters in diameter, at a depth of nearly 100 meters, on which grooves run along the bottom. It looks as if the object at high speed entered into the water and traced along the bottom of these grooves. (see a photo of sonar). Peter Lindberg, the team leader says, that he at first time sees like object on the seabed, although he spent thousands of hours behind the screen of sonar. The Swedish team "Ocean Explorer" for many years engaged in search of treasure from sunken ships. Now Peter Lindberg is looking for sponsors, which will help him explore the details of the UFO at the bottom of Gulf of Bothnia. Official webite of Ocean Explorer: http://www.oceanexplorer.se
