Baltic Sea Anomaly Details: Is it a UFO or Hoax [video] Unidentified Submerged Object

Updated on August 31, 2014

See unreleased Baltic Sea anomaly sonar pictures and video. If the submerged object, (USO), is a hoax, why did the government classify all of the researcher's data? A real unidentified submerged object is found and the pictures show a major operations base.

Baltic Sea UFO is a USO (unidentified submerged object)

*reporting for the Daily Constitutional: Investigative Journalist GA Anderson

January 31, 2012

Is the Baltic Sea "UFO" a hoax, or did they find a real Millennium Falcon? "Is it a UFO, USO, or something else?"

UFO believers are serious, but non-believers are snickering, and a story that first broke in August of 2011 has resurfaced with new details. The major media outlets ran the story as a tongue-in-cheek jab at UFO believers, snidely commenting that a Baltic Sea underwater research vessel has found the real "Millennium Falcon," but no one is mentioning that the Swedish government declared they had maritime authority of the site and seized the researcher's computers and all records of the incident.

So is it really a hoax, an underwater anomaly, or a multinational conspiracy to suppress facts that may indicate an extraterrestrial event?1

Peter Lindberg and Ocean X

The Baltic Sea UFO Finding

In July of 2011 underwater research specialist Peter Lindberg, of the research vessel Ocean Explorer, was returning to port from a month long search for Baltic Sea shipwrecks. Following a typical return-to-port practice, they were towing an underwater sonar sled using side-scanning sonar to map the sea floor as they returned. But 187 miles off the coast of Sweden the trip became anything but typical.

The image on the sonar display screen seemed too well defined to be a natural seabed formation, and its obvious similarity to a disk-type craft too much to ignore. Lindberg quickly called the rest of the research staff down and directed the ship to begin making more lateral passes over the object. The above photo is the image he first saw on the monitor.

Baltic Sea UFO Details

After the initial excitement, the research team began to compile and evaluate the details of what appeared to be a non-natural seabed find. It was the sharp edge delineations of the image that strongly indicated the object was not a natural rock or sea-floor formation.

The object is in almost 300 feet of water, and is approximately 195-200 feet in diameter. There is also what appears to be a 1600 foot "skid-path" behind it. Because of the nature of side-scan sonar, in loose sea-floor silt like in the Baltic Sea, it can sometimes return images that are actually embedded, rather than sitting on the surface. Efforts to determine the height of the object were non-conclusive. According to Lindberg it could be 10 feet tall, or 50, and it was also not possible to determine how much of the object could be embedded below the surface.

The similarity of its shape to the movie starship was not lost on the crew either. It is believed that it was a crew member comment to a dockside reporter that prompted the public comparison. It is also believed that leaked details of ship-to-shore radio communications advising the expedition's sponsors of the find, and the reason for their delay to port, were responsible both for the crush of reporters, and the government officials that awaited the Ocean Explorer when it pulled into port.

The Official Report

It is not unusual for research expeditions such as this one to pledge crew members and research staff to confidentiality agreements, but it is unusual for port authorities to quarantine an arrival as they did this one. Officials boarded the ship, even as the mooring lines were being set, and it was almost 4 hours before Peter Lindberg appeared and gave an impromptu press appearance at the foot of the ship's gangway.

According to Lindberg, due to the unexpectedness of the discovery, and the limited amount of resources available at the time, he would only be able to give the basics of their information. Further study of the sonar data, and possibly even another expedition, would be needed before there could be any conclusive answers as to what the object was.

He then referred all further inquiries to the expedition sponsor, Baltic Finland LC, an investor partnership.

*Note: In a later email to ABC News, Lindberg stated that further study of the image had narrowed the list of possibilities, but it would still take more investigation, possibly using an unmanned underwater sub, before anyone could even make an educated guess as to the identity of the object.

Media Reports on Baltic Sea UFO

The Non-official Story of the Baltic Sea UFO

In what appears to be a "Wikileaks Redoux" event, the Danish website,, has posted interview transcripts, images, and emails that it says prove the Ocean Explorer's find was much more than what the public has been told, and that there was a multinational government effort to keep the real information secret.

The released documents, (supposedly from thumb-drive data a research member concealed from Swedish officials), detail an obvious and concerted effort to suppress the data from public release, but it is the additional sonar images that are most damning. Not only do they show there is much more to the finding site than has been told, but they also show that the publicly released image was only a cropped portion of the real sonar data.

Baltic Sea UFO Image Explanation

According to Leigh Dostra, an imaging data analyst in Lindberg's research group, the original sonar scans actually showed three distinct objects, not just the cropped image that was released. She also stated that it was the Swedish officials that determined which part of the image to release to the public.

Original round object:

The research group determined that images a. and c. were two broken pieces of one object. Indicating the original shape would have been suacer-like, not the "Millennium Falcon" shape that the media has ridiculed. Computer-matching of the two pieces show they could fit together, and their combined area would be almost 325 feet in diameter. They also determined that the "skid-path" was approximately 600 feet, not the 1600 feet original mentioned to the media.

Long tubular object:

The longer and larger image b., is the most mysterious part. It appears to be approximately 920 feet long, and 205 feet wide. And hollow.

Compartments and Passageways?

Deep-sea acoustic imaging

According to Dostra, the Ocean Explorer was equipped with several other types of imaging equipment. The above image is from an acoustical scan taken from above. The density results show the object to possibly be honey-combed with compartments and passageways.

The large circular center portion may to be one large open area, while the "wings" on each side appear to be compartmentalized with darker "veins" that could be passageways. Dostra cautioned that this is only speculation at this point. Better equipment, and closer scans are needed before any interior details could be confirmed. She did comment that the uniformity of the segment's "grayness" indicated open volume, not solid material.

More imaging Results

Using computer simulation software, the Ocean Explorer researchers were also able to combine thermal and acoustic density imaging on the original "starship" object.

The top image is the result of the side-scan sonar data, although much of the edging seems very distinct, Dostra cautioned that sea-bottom silt refraction could be responsible for the apparaent delineations.

The middle image is a combined thermal and acoustic density image. The red colorations were explained to be caused by oxygen output of seabed vegetation, and the lighter blue/teal colors represented non-living organics. It is the darkest black and gray lines that were most interesting. Dostra explained that these represented verticals, and in this image, the verticals were much too uniform to be natural formations, they almost certainly had to be man-made, or perhaps, alien-made.

The bottom image is an artistic rendering created from the therm/density image by an animation studio based in Finland. Understanding that it is a speculative rendering, it is still based on real data points that are just rendered in a different format. Similar to the way current animation software uses real-time motion data points to simulate human body movements.

Do you believe in UFO's?

Natural, UFO, or Hoax

Is it a natural formation - misinterpreted by the sonar readings, or a real UFO? There is enough of both ambiguity and detail to form an opinion either way, it just depends on how you interpret the data, but what is clear is that the government quickly jumped in and quashed a full release of all the data. The real question is why?

Author's note: two days after posted this data, the site went dark. The site owners said they were hacked, and their servers wiped clean, but so far they have been unable to trace the source of the hack. They have also been unable to recover any of their server data - or locate the original thumb-drive that was stored in an office safe. - GAA

      While I agree the "Top Secret image" does seen photoshopped, I do find the original one highly interesting. Features that smooth and clean don't appear in nature, at least not often (meteor impact craters are the only thing I can think of that would have anything near that symmetry).

      I want to point out that I do believe in UFOs, and even though I find myself being skeptical of some sightings at times, the sheer weight of what has been reported over the years begins I take on a believability factor of its own after a while

      Entire civilizations and continents have been found under the sea. Why would this be any different. The idea of 'UFO' can't be any less bizarre than the lost continent of Atlantis. We come from somewhere, and the day will come when our present land masses will be discovered and similar questions will be asked..What are they? Where did they come from..A lot of scientific time and expense is wasted looking for something really 'new'.

      Are you sure?

      Can you be sure it is not just the common structuring of sonar imaging of the Baltic Sea UFO anomaly?

      You can see those pictures are badly fabricated.

      You have to admit there's something not right about all of this. My warning to everyone is to keep quiet, because you could end up looking a bit stupid if this all turns out to be a big hoax. I can understand that people love a mystery but don't get carried away. Anyway, there are far more curious events to look into if you like a bit of open minded speculation.

      The" complete sonar side scan image" seems to be a hoax created by applying the copy and past as well as the rotate and zoom functions of a bitmap painting software.

      Interesting..Either you way you look at it, what the hell is it? If you look closely, both sides of the objects are identical to one another. Mother nature nore the depths of the sea didn't create that...something did and it wasn't man..

      @KM1 - thanks for reading "Baltic Sea UFO, Unidentified Submerged Object, or Hoax," and yes, I do enjoy writing these type of articles.

      They are often misunderstood - as some of the comments show.

      Wow, people need to COMPLETELY read the article before commenting. Of course, comments from the likes of "Davy Jones" are what make these tongue-in-cheek readings amusing.

      My 10 year old could make a better fake side scan sonar image then that "top secret" copy and she doesn't even know what sonar is. This dagged and multi copied image will only fool the tin foil hat crowd. Be skeptical but have an open mind, those Swedish divers have been both.

      Stop faking that original picture.

      The one that's supposedly top secret and wasn't shown, is one of the lamest windows paint fakes I've ever seen ever!

      There's only one real picture and that's the one floating on the net everywhere.
