The Baltic Anomaly: UFO…or just a Hot Spring?

As we speak, Ocean Explorer is investigating the ultra-strange Baltic Anomaly, a gigantic underwater formation. Numerous explanations have been put forth, with a crashed UFO being one of the most prominent. But could the Anomaly be nothing more than a hot spring?

Background on the Baltic Anomaly

This is an exciting time for fans of the unexplained. Next month, TIGHAR will launch its latest expedition to Gardner Island in search for answers to Amelia Earhart’s mysterious disappearance. And right now, Ocean Explorer is searching the depths of the Baltic Sea for answers of a different sort.

For those of you who haven’t been following the story, last summer Ocean Explorer used side-scan sonar to “photograph” a strange object deep in the Baltic Sea, approximately 260 feet below surface. The object is about 200 feet in diameter, with a tail stretching over 1,300 feet across the sea floor. Its exact nature is unknown and thus, Ocean Explorer has returned to the site to give it a closer look.

Skepticism over the Baltic Anomaly

Now, I have to admit I’m skeptical of Ocean Explorer. They seem to have no problem fanning the flames of conspiracy theorists, which is far from a good idea for a scientific expedition that wants to be taken seriously. Take this tweet from May 30 to see what I mean.

“Do you know that there is a large military exercise in the Baltic Sea now, with Germany U.S., england. why is it so … what do you think?” ~ Ocean Explorer, May 30, 2012

This military exercise is real…but very easy to explain. Since 1971, United States Naval Forces Europe has participated in BALTOPS, an annual military exercise in the Baltic Sea. So, this looks like nothing more a weak attempt to get ufologists paranoid over military intervention. That’s a pretty big strike against Ocean Explorer’s credibility as far as we’re concerned.

As such, we’re required to take their statements with a grain of salt. That being said, here’s an interesting update from two months ago, which as far as I know hasn’t seen much discussion yet.

“incredible, we have measured the radiative value of the anchors we used. It’s quite intriguing, the normal level of radiation is 0,1 milli Sieverts and we get 0,63 when measuring on the anchors. It’s far from dangorus levels but still; it’s 6 times higher than a normal level of radiation. The anchors have been on the bottom like 2-3 kilometers from the circle, so one can wonder if we will get higher values of radiation the closer we get of the circle?” ~ Ocean Explorer, April 2, 2012

Six times normal radiation levels? Now, that’s a story. The cause of the radiation is unknown but of course, it’s assumed to be associated with the Baltic Anomaly. That begs the question…what could cause such radiation? Well, there’s actually a fairly easy answer…hot springs.

Guerrilla Explorer’s Analysis

Hot springs are created when groundwater in the Earth’s crust is heated by geothermal means. They are found all over the world. Sometimes, they contain radium. In fact, the famous hot springs in Ikaria, Greece, enjoyed by people for thousands of years, are radioactive. Here’s another example of gamma radiation being found in hot (and cold) springs in Jordan.

Now, geothermal heat appears to be quite common in the Baltic Sea. Plus, a large hot spring would explain more than the elevated radiation levels. It would also explain the shape of the Anomaly as well. When hot water is expelled from a hot spring, it causes dissolved minerals and the surrounding soil to be driven outward. These materials eventually cool and harden in the water. All in all, this might account for the vast amount of disturbed seabed as well as an object that looks like a sandbar.

So, is the Baltic Anomaly a hot spring? A natural rock formation? Something else? Well, the last report from Ocean Explorer stated they were “on a roll” as of June 4. So, in all liklihood, we should have answers soon.

The Baltic Anomaly?

Last summer, Ocean Explorer used side-scan sonar to “photograph” something strange deep in the Baltic Sea, approximately 260 feet beneath the surface. Is it a natural rock formation? Or something else entirely?


The object in question is about 200 feet in diameter, with a tail stretching over 1,300 feet across the sea floor. And no one knows for sure what it is. Opinions range from the plausible (a natural rock formation) to the wild (an Unidentified Submerged Object, or a USO).

Yesterday, a team of researchers led by Peter Lindberg and Dennis Asberg converged on the mysterious object. They plan to study it for 6-10 days.

“We’ll be searching the area in a number of ways. We’ll use sonar to make 3D images of the bottom, the clay bottom, of that part of the sea. We’ll send down deep-sea divers too. And a camera robot. We’ll also take samples from the sea bed and measure them for toxicities and radiation.” ~ Peter Lindberg

So, what is this thing? Some of the more realistic suggestions include: crash debris from a meteor, a natural gas well, or a shipwreck. Perhaps the most likely option is that it’s nothing at all.

“Side-scan sonar is not a photograph and it can create false echoes, so it’s not crystal clear what exactly it is that you’re recording. The object that we’re talking about is basically flush with the ocean floor, and side-scan sonar is much less reliable for things like that.” ~ Benjamin Radford, Deputy Editor, Skeptical Inquirer magazine

So, the jury is still out…at least for now. But we should have an answer in a couple of days. Stay tuned!

A Lost Shipwreck…or a Lost UFO?

A few months ago, Ocean Explorer used side-scan sonar to “photograph” something strange deep in the Baltic Sea, approximately 260 feet beneath the surface.


It’s a circular UFO-like object (or to be accurate, I guess a USO), about 200 feet in diameter, with a tail stretching over 1,300 feet across the sea floor. While some experts believe it’s nothing more than a natural rock formation, many others are extremely curious about it. Ocean Explorer hopes to get a closer look at it in 2012 and is seeking funding to do so. Until then, here’s a good update on the story from CNN:

Deep down on the bottom of the Baltic Sea, Swedish treasure hunters think they have made the find of a lifetime.

The problem is, they’re not exactly sure what it is they’ve uncovered.

Out searching for shipwrecks at a secret location between Sweden and Finland, the deep-sea salvage company Ocean Explorer captured an incredible image more than 80 meters below the water’s surface.

At first glance, team leader and commercial diver Peter Lindberg joked that his crew had just discovered an unidentified flying object, or UFO.

“I have been doing this for nearly 20 years so I have a seen a few objects on the bottom, but nothing like this,” said Lindberg.
