The Strange Object in the Baltic Sea
A mysterious circular object sent shockwaves around the marine biology world when it was found at the bottom of the Baltic Sea in 2011. To date, the object has continued to confound researchers because the origin of the object and what it really is, still remains a mystery; it was therefore dubbed the Baltic Sea Anomaly as a result.
The strange 61-meter object was found by a team of Swedish treasure hunters led by Captain Peter Linberg; their side-scan sonar aided the discovery as it picked up the submerged object.
