hmm very interesting i like the idea that is some sort of stonehenge like monument or maybe an underwater marker of some sort anyways i really hope they do some more exploration on this

Could be something like a placed sensor package or an underwater drop-box of sorts. Towed into place by some ship, and then anchored with concrete.

What? When it comes to submarine warfare, do you think NATO or Russia tells people about these things?

No matter what it turns out to be, I think it would be interesting to take a closer look. At least that should end the guesses and speculation.

First thought: Underwater Caldera
===========================
A Caldera, as many of you know, is a crater-like hole or cavity caused by a specific type of volcano. This feature is normally associated with volcanoes that have already erupted. These types of volcanoes can be super-volcanoes, which are incredibly massive and destructive.

This type of bubbling up, slowly, then collapsing in on itself could potentially create the formation we're seeing here. The edges would be slightly raised up in relation to the surrounding see floor.

The "skid mark" could easily be the result of this formation causing interference in the normal flow of water through that area.

Circular shapes are not that odd, from a natural perspective
============================================
When you start seeing geometric regularity, like right angles, boxes, and repetitious geometric patterns then red flags go up and you think this thing may be artificial. But a circular shape, or a cauldron like depression, or crater are very normal and natural occurrences.

I think trying to attribute this to a UFO is a very weak logical leap: It's a disc shape when looking at it from the top down, therefore it might be a giant disc-shaped ship. There is a skid mark, maybe like one you'd see scraped over someone's lawn if a smaller disc shaped craft crashed there? I'm going to say no on this one. Seem like too weak of a connection.

The observer
============
I don't think the discovery can be immediately dismissed as unimportant natural phenomenon. You have to consider that this experienced diver is claiming to have "never seen anything like it" in almost two decades worth of diving experience.

It is certainly possible that he has never seen an underwater caldera in person. This type of finding would certainly be incredible!

The observer made the claim that it was concrete, rock, or steel, or something like that. I would like to hear more about that. Did he touch it? Did they get a better picture? How close did they get in person? Did they recover a sample?

TL;DR
It's interesting, but I think we can rule out artificial unless some pretty remarkable evidence is produced. An underwater caldera seems more likely.

Cool, obviously a fossilized mk II medium recon ship from civilization 1



Cosmic...

I noticed in the Yahoo article they said this was discovered in August...has been a thread on here since February 2011...

Calderas are far larger than this, so that explanation doesn't fit. Volcanos tend to create mountains, so that does fit either, unless someone knows of a caldera or volcano that fits this description.

From the links provided, the Russians only made 3 of these round ships, and all three are accounted for, so unless there is some record of a fourth ship that somehow wound up near Sweden, than this explanation that it is one of these Russian ships is extremely unlikely.

While 300M is not an impossible depth, it is certainly very deep, and a challenging costly dive. I hope someone gets the chance to explore this further. It sure makes one think crashed UFO.

Unreported sunken oil rig maybe?

so could this be the start of project bluebeam??
( meaning they pull the ship out = Alien Invasion? )

Exactly. If it is true there are track/skid marks, it's not likely to be some underwater Stonehenge now is it?
Something was moving and came to rest. I'm guessing there is a more mundane explanation than folks would like. Otherwise - don't you think the authorities would be all over this like a rash?

From one of the threads that was closed (because you all beat them) sounds like a return trip may happen in May when the Baltic calms enough to increase safety.

could it have something to do with that phenomenon that happened in Norway a while back? On the map it is close. Could it be?
