A “UFO-shaped” object, found at the bottom of the Baltic Sea last year, has puzzled many. And a Swedish expedition that plunged into the deep eventually surfaced with more questions than answers.
Covered in soot, with little “fireplace”-like structures and lying at the end of a 300-meter “runway” – this is not something you would expect to find sitting on the sea floor. And whatever you think about extraterrestrial life, “the thing” is still there and there has to be an explanation. So what could it be?
On June 19, 2011, a team of Swedish treasure hunters was exploring the bottom of the Baltic Sea with their sonars when they noticed a bizarre, disc-like structure at a depth of 90 meters. Back then, international experts failed to explain the sonar images. In 2012, after months of preparation, the Ocean X Team, as they call themselves, went back in order to unveil the mystery.
“Since no volcanic activity has ever been reported in the Baltic Sea, the find becomes even stranger,” said Lindberg in a press release at OceanExplorer.se. “As laymen, we can only speculate how this [could be] made by nature, but this is the strangest thing I have ever experienced as a professional diver.”
Another observation that the crew made in person was the 300-meter-long “trail” that they described as a “runway or a downhill path that is flattened at the seabed with the object at the end of it.”
The group says that they passed samples from the object to scientists for further examination. Other experts are studying the sonar images and processing the rest of the data from the ship. It is worth mentioning though, that sonar-based imagery has been known to become a source of confusion, when natural rock formations have been taken for foreign objects.
