The Baltic Sea Anomaly




The Baltic Sea anomaly refers to an object found by the Ocean X diving team in the Northern Baltic Sea at the center of the Bothnian Sea in June 2011.

Ocean X is a treasure hunting company lead by Peter Lindberg and Dennis Asberg and is specialized in the retrieval of objects from sunken ships.

They use sonar and radar equipment and a team of divers to locate and investigate wrecks. The sonar images of the Baltic Sea anomaly showed a circular object with unusual features indicating something that is not created by nature but more likely man-made or as some suggested made by extraterrestrials.

The team suggested their sonar image showed an object with unusual features of seemingly non-natural origin, prompting speculation published in tabloid newspapers that the object was a sunken UFO.

The 3-D sonar scans revealed smooth walls and straight corridors all over the surface of the object. Some of the edges reflected the sonar waves in a more intense way indicating the possible existence of a much harder material under the surface, possibly metal. The walls of the corridors are perfectly straight and have right angles to the floor.

Dennis Åsberg said: "When we went out and saw the walls which were straight and smooth, it was frightening, as in a science-fiction film".

The object has a diameter of 60 meters (196 ft.) and lies about 87 – 90 meters (285 ft. – 295 ft.) under the surface of the sea. There is a second similar piece detected about 200 meters (660 ft.) away, which has a diameter of 40 meters (130 ft.). Judging on the two 1500-meter (5000 ft.) trails leading to each of the objects, they seem to have both crashed at the same place before sliding to their final destination leaving deep trails behind in the seabed. It is quite possible that they were one single object before the crash.

There are many theories on what the Baltic Sea Anomaly could be, but none of these theories are final as there is not enough information for a clear-cut conclusion. The objects are very deep under the surface and difficult to reach. There have been no overview pictures as it is too dark and murky. For now, we can only go by the sonar images made public by Ocean X, which unfortunately are plagued by a number of distortions caused by equipment calibration issues.

This document is my attempt to analyze what the Baltic Sea Anomaly could possibly be and to illustrate my thoughts on what I see in the object. It is not a real open-minded analysis, as I will not go into any of the other possibilities people suggested. In fact, I am not going beyond illustrating my own initial thoughts on what we are dealing with. As a disclaimer, I would like to add that this document is not meant as a fair analysis as it is jumping quite rapidly to a single conclusion.



Many theories

Having a quick search on Google for The Baltic Sea Anomaly results in a large number of explanations with some very far-fetched theories. These theories include Atlantis temples, UFOs (the Millennium Falcon) and volcanic rocks.

The Baltic Sea Anomaly seems to have no purpose in its current location and it would, therefore, be more likely that an accident happened during transport, which caused it to sink and break apart. The 1500-meter trail on the seabed is very puzzling as it is unclear how such a heavy structure could slide for such a long distance. Some researchers reason that glaciers could have dragged it during the ice age, which would definitely explain the trails. However, the problem with that theory is that the structure would have been built on dry land when the Baltic Sea was still dry and it would, therefore, be thousands of years old. It would place the Baltic Sea Anomaly in a time period that humanity did not yet have the ability to create such structures and it would conflict with our current accepted history. This theory, therefore, creates more questions than it answers.

Although it would be very exciting if the Baltic Sea Anomaly would be extraterrestrial or a temple from Atlantis, I fail to shoehorn my observations into such far-fetched ideas. My conclusions on what the Baltic Sea Anomaly could be are much closer to home and indicate a much more recent time period for its construction.


The method used

The method used in this document is to compare the form and patterns found in the features of the Baltic Sea Anomaly to known objects. The idea is to use the similarities to answer the following questions:


  • What is the Baltic Sea Anomaly?
  • How did Baltic Sea Anomaly arrive at its current location?
  • What was the purpose of the Baltic Sea Anomaly?


The method used is simplistic and generally has a limited usefulness, but with this visually striking Baltic Sea Anomaly, we can actually get rather far in our deductions. The main characteristic features of the circular object are the straight lines forming rooms and corridors. These line patterns create features that can be compared and matched up to characteristic features found on other similar, man-made objects and especially with seaside bunkers and fortifications. These similarities we will use to shed light on what the Baltic Sea Anomaly could be.

To start answering any of the above questions we first need to have a better idea of what the Baltic Sea Anomaly looks like. For this, I created a virtual model using the measurements calculated from the sonar images. The tape measurement tool of Google Sketch-up was used to measure each of the corridor walls and features found on the object. The calibration of the Sketch-up tool was based on the initial estimation given by the Ocean X team that the Baltic Sea Anomaly is 60 meters in diameter.

The methods used did not result in creating a perfect copy, as there are many factors causing distortions. The starting challenge was to read and understand the original sonar images. These images were vague and distorted because of calibration issues with the sonar device. Further challenges were related to the modeling process itself. It was an artisanal and manual process and includes many assumptions, trade-offs, and interpretations. As a result, the final virtual model is far from a true representation of the original Baltic Sea Anomaly. Keeping that in mind I do think the model resembles the original object enough to give an idea of its possible purpose.

Modelling process of the Baltic Sea Anomaly

The Baltic Sea Anomaly - the modeling process 


The advantage of working from a virtual 3D object is that it can be manipulated and seen from many angles while it can also be “dressed up” and placed in its natural (virtual) environment making it easier to understand its original role and purpose.

Two of the sonar images released by Ocean X have been used as our basis for creating the virtual model of the Baltic Sea Anomaly. The first image has more details but contains distortions caused by calibration issues with the sonar device, while the second image is very vague. Compared to each other they show significant differences. Therefore the vague image has been used to correct the detailed image before creating the model of the Baltic Sea Anomaly.

Modeling a virtual model of the Baltic Sea Anomaly 


I modeled the virtual object in Blender (version 2.79). Although much attention was given to details there are some small omissions that were not picked up until a later stage when it was not anymore time-effective to go back and update the model. In case of doubt please always refer back to the original sonar images. The resulting virtual model is now used as the basis for the analysis and is compared with historic objects that may help to discover the purpose of the Baltic Sea Anomaly.



"The images has previously shown defined 90 degree angles. Many 90 degree angles and straight lines: .5 – 1.5 meter ( 1.5 to high 5 feet) corridors within object. They appear to be like passages or walls approx. 1.5 meters in height and 3 meters (10 feet) wide, which are cut into the object. The walls are straight and smooth. The walls are made of stone resembling sandstone."

The Baltic Sea Anomaly is 4 meters high and rests on a what looks like a pillar or an additional layer with a different diameter which lifts the object about 9 meters from the seabed.
