Ocean X Team, who first discovered the anomaly in 2011, have found another huge object in the Bothnia region of the Baltic Sea. The team, who discovered the anomaly while hunting for shipwrecks, returned to the site on June 8 with a remotely-operated vehicle (ROV). They lowered the ROV at ‘Anomaly 2’, a huge “monolith” and a “slab” – and were stunned when their compass “went berserk” – an inexplicable machine failure that has previously occurred while investigating the site.
Moments later, the team were again shocked when the their vehicle discovered another unexpected item at the site, which alien-hunters believe could be a crashed UFO.
A statement from the group, led by Swedish explorer Peter Lindberg, said: “It was very difficult to understand where the ROV were because of the terrible visibility and because of the compass that went berserk.
“The compass was living its own life and the tether was snagged all the time.”
Finally the image cleared and the group could begin investigating what they assumed was the “monolith” or “slab” identified in earlier operations.
The team then had to return to shore due to fuel issues.
However, when analysing the footage later they realised they had not been investigating the “monolith” or the “slab” and had instead discovered a collection of inexplicable stone “walls” buried in the ocean floor.
The statement said: “The surface between the ‘walls’ are buried beneath 200mm of sediment but it seem to be hard, straight and smooth.
“The ‘walls’ are sticking up maybe about 200mm above the sediment.
“We did not really realise that it was neither the slab or monolith we actually were investigating.
“The rectangle is actually located between the two objects that are visible on the side scan sonar image but we did not realise that when we were still at site.”
They said, like the other discoveries at the site, the objects could be man-made.
The statement concluded: “Is the rectangle made by the nature or by someone!? That is something we need to find out!”
The site has intrigued conspiracy-hunters since it was discovered – with inexplicable technical problems plaguing anyone who tries to investigate.
Stefan Hogerborn, a professional diver with Ocean X, said previously: “Anything electric out there, and the satellite phone as well, stopped working when we were above the object, then when we got away about 200 metres, it turned on again.”
Mr Lindberg previously said: “Mr Lindberg said: “I have been the biggest sceptic, I was kind if prepared for finding just stone. For me it has been an amazing experience.
“I think it is very odd in its shape. It is tough to give an explanation as to what it might be exactly, since different scientists have many different theories.
“Whatever it is, it is something we do not usually find in nature sitting in the dark cold depths of the Baltic Sea.”
It is thought the object could be at least 140,000 years old after a university professor linked the mysterious disc to the Ice Age.
Volker Bruchert, an associate professor of geology at Stockholm University, said: “My hypothesis is that this object, this structure was formed during the Ice Age many thousands of years ago.”
