Lindberg explained to local media that his crew discovered, on the 300-foot-deep ocean floor between Finland and Sweden, “a large circle, about 60 feet in diameter. You see a lot of weird stuff in this job, but during my 18 years as a professional I have never seen anything like this. The shape is completely round.”

Adding to the mystery at the bottom of the Gulf of Bothnia, Lindberg said he saw evidence of scars or marks disturbing the environment nearby, suggesting the object somehow moved across the ocean floor to where his team found it.
