Baltic Sea UFO Anomaly: New shocking evidence deepens mystery

Baltic Sea Anomaly since its discovery has grabbed the attention of the scientific community due to its mysterious origin and nature.

In 2011, Peter Lindberg, Dennis Asberg and their OceanX diving team found the anomaly, while searching the Gulf of Bothnia, in the form of an unusual artificial circular shape characterized by central depression and stair-like ridges, thereby sparking different theories related to UFOs and a sunken city.

Most of the experts attributed this circular symmetry to natural geological formation shaped by glacial processes. The samples retrieved from the site consisted of sandstone, granite, and gneiss, indicating a natural process that occurred during the last Ice Age.

On the contrary, Swedish wreck diver Dennis Åsberg, co-founder of Ocean X, has emphasized on the artificial origin of the shape on the grounds of unprecedented observations.

While talking to Jesse Michels in a podcast, Dennis shed light on new evidence and the oddities of the structure found in the 90 meter depth of the Baltic Sea.

Detached from seafloor

According to the new evidence based on the latest sub-bottom profiling, the circular structure was found to be detached from the seabed, thereby downplaying the theory of natural origin. It is resting on the seafloor, not rising out of it. In 15 years, this is the most important data related to Baltic Sea Anomaly.

Perfect right-angle geometry

According to the Swedish diver, the geometry of the structure is not natural. It consists of straight walls, 90° corridors, and a hard, uniform surface.

Presence of metallic components

The lab tests also revealed organic material and basalt in the samples. The presence of basalt goes against the natural occurrence of the structure.

Tech malfunctions

The expert also reported the tech malfunctions near the site. During the multiple expeditions, the team recorded GPS failures, electromagnetic interference and cameras shutting down over the object. Even Stockholm University research vessels also experienced such kinds of interruptions.

Temperature & biological oddities

Water temperature around the object was recorded nearly to 0°C compared to other parts of the Baltic sea.

A large circular opening appeared to be pulsing sediment in and out, described as “breathing” more like a biological organism. Moreover, the presence of biological debris also deepens mystery about its nature and origin.

Long before the discovery of the anomaly, Dennis also witnessed a 600-700 meter cigar-shaped craft flying over a Swedish plutonium facility. This incident anchored his belief in UFOs and the objects that defy traditional explanations.

Despite the observations from the scientific community, Baltic Sea Anomaly has remained an enigma for the world.
