Probably natural feature of some description - be interesting to see what exactly.
Original report on this seems to CNN back in January :
Shipwreck hunters stumble across mysterious find.
(CNN) -- Deep down on the bottom of the Baltic Sea, Swedish treasure hunters think they have made the find of a lifetime.
The problem is, they're not exactly sure what it is they've uncovered.
Out searching for shipwrecks at a secret location between Sweden and Finland, the deep-sea salvage company Ocean Explorer captured an incredible image more than 80 meters below the water's surface.
At first glance, team leader and commercial diver Peter Lindberg joked that his crew had just discovered an unidentified flying object, or UFO.
