In the Gulf of Botnia between Sweden and Finland, Swedish divers have discovered this:

The "object" is at about 90 meters, and according to the discoverers, the treasure hunt organization Ocean Explorers, it is about 60 meters in diameter.

There is supposedly a 300 meters long "glide track" next to the object, leading UFO nuts to "know" that it's a crashed space craft.

A marine archaeologist said to Swedish press that he can't know what it is, but that it is most likely a natural formation.

I open the floor to wild speculations.
 
Indeed it is. Just heard about it. Was beaten to the post with half a year. :o

Wasn't divers, or there wouldn't be speculation about what it is. The picture is sonar taken from the surface. At 90 meters, it would be easy to send an camera down there to take some pictures and end the speculation. The fact that this wasn't done tells me that the people operating the boat don't really believe it's anything that amazing.
 
The funny thing is that the "object" is not an object at all, it's a hole. A quote from one of the articles about it:

Lindberg explained to local media that his crew discovered, on the 300-foot-deep ocean floor between Finland and Sweden, "a large circle, about 60 feet in diameter. You see a lot of weird stuff in this job, but during my 18 years as a professional I have never seen anything like this. The shape is completely round."

This guy is not very good at his job if he's never heard of a round sinkhole before, and doesn't know that the dark area in his sonar represents a depression, not an object sitting on the ocean floor. Google "blue hole" for a much more impressive one.

Listened to them interviewed on the radio yesterday. They said with some reservation that it most likely isn't anything spectacular. They also insisted that they haven't made any money from this and in fact have lost money because of being taken in by frauds posing as investors. Oh, and they have a tv-show coming out soon. :D
 
Baltic seafloor geology, especially in the north, is to a great extent Precambrian basement - gneiss, mostly. I have no idea where this find is, but I'd note that basement this old has had lots of time to be hit by meteors...
Which often results in circular depressions.

The critical factor would be the nature of the sea bed in the immediate vicinity, but if there is solid rock at surface- if the area was recently scoured by glaciers for instance, which is not impossible- it might be a crater. I can't get the vid to play, don't read any Scandinavian language and have zero expertise in sonar interpretation, so I may be missing clues here, but if I see a circular depression on a seabed, my first thought is crater- volcanic or meteoritic- and I think we can rule out volcanic.

ETA- If a crater, it's probably very old, so the edge is not the original impact rim. But if the material inside erodes differentially from that outside , and it has been subject to ice related erosion in the last 10,000 years, it might appear quite fresh.

Make sure they know to keep the troops away from the door of the USO; best tactic is to position them at range in an arc around the area, with good cover, and use particle dsiturbance grenades two spaces in front of the door (if you put them one space in front of the door, they blow when the alien gets to the door, thus the door shields them from blast).
 
it's an excellent preservation agent, the water's not too salty and whatever's downthere will be in an excellent shape when they pull it out

Only there's nothing for them to pull out... If there was, they would have done it last year when they found it.

x-com?
 
There are many many strange looking "things" on the ocean floor. None that I have ever checked out (dive) were alien in nature. Boats, planes, even cars but no star ships.
