From the press Ocean X Team press release on 16th June 2012:
Treasure hunters confirm they have identified one thing abnormal in the seabed
The Ocean X Team dove down to the circle-shaped object in the Baltic Sea and met something they never ever skilled prior to. First they thought it was just stone or a rock cliff, but after further observations the object appeared more as a massive mushroom, rising 3-4 meters/10-13 feet from the seabed, with rounded sides and rugged edges. The object had an egg shaped hole leading into it from the top, as an opening. On top of the object they also located strange stone circle formations, nearly looking like tiny fireplaces. The stones had been covered in a thing resembling soot.
“During my 20-year diving career, like 6000 dives, I have by no means noticed anything like this. Normally stones don’t burn. I can’t clarify what we saw, and I went down there to answer questions, but I came up with even a lot more questions “, says Stefan Hogeborn, one of the divers at Ocean X Team.
The path to the object itself can be described as a runway or a downhill path that is flattened at the seabed with the object at the finish of it.
“First we thought this was only stone, but this is something else. And since no volcanic activity has ever been reported in the Baltic Sea the find becomes even stranger. As laymen we can only speculate how this is made by nature, but this is the strangest issue I have ever knowledgeable as a skilled diver“, continues Peter Lindberg, one of the founder Ocean X Team.
Proper now, scientists are examining samples from the circle-shaped object, and professionals in sonar imaging are processing information from the ship to hopefully shed more light over the mysterious object ( via oceanexplorer.se ).
