World record on ice "Finland's four-time world rally champion Juha Kankkunen drove a Bentley Continental Supersports convertible on the hazardous frozen waters of the Baltic Sea, off the coast of Finland, at a breathtaking 205.48 mph (330.695 km/h) to set a new world speed record on ice."

Baltic Sea ice extent just passed last year´s maximum. Current extent is about 250 000 km2 and we have to go back to the season -86/87 to find higher values. The deep lake "Vättern" in Sweden is now totally covered with ice for the second year in a row which is something that statistically happens every 7th year but is more frequent around solar minimums. www.smhi.se/oceanografi/istjanst/produkter/sstcolor.pdf

"I think I found the missing arctic ice." At least the Baltic ice will be totally gone by June. I can see there are quit a few Baltic fans out here. There's an educational way to enhance your Baltic-related experience. The Stormwind boating simulator stormwind.fi/sv/component/kunena/ The current beta version is free, but you'll need to register at the forum, where the download resides. Endorsed by the Finnish Boating Association, among others. If you're running XP, chances are you'll need to download Managed DirectX 9 from Microsoft (free) for the sound to work. This version will give you a large portion of the Baltic to crash your boat on rocks on around the island of Jurmo.

"http://www.marinetraffic.com/ais/se/default.aspx
Look for baltic. Square are ship not moving, stuck in ice. Yesterday was 60 ship stuck in ice."
Northspinx, are you referring to the blue diamonds? They are typically moored vessels. For instance, you would see the Oili 2, which is a moored anti-pollution ship, and other such vessels. Where traffic typically gets constained on high winds in the winter is the area between Vaasa (Vasa) and Umeå, but there seems to be no good AIS coverage there.

Naturally, Northsphinx, ships don't moor in the middle of the sea. Therefore, you'll see no blue diamonds (not "squares" btw) in the middle of the Baltic in AIS.
In the AIS system the moored vessel sets her status accordingly. When the vessel actually sails, and if the crew is awake, the status will be changed to signal the destination and estimated time of arrival. That info in accessible in marinetraffic.com by clicking on the vessel icon.
Furthermore, there's no way to tell whether a ship is "stuck" or just waiting for her turn to be assisted, or waiting for a berth to be freed.
Perhaps you'll tell the first 10 IMO codes of those 60 vessels you saw "stuck" in AIS in the Baltic so we could followup? They would not have sailed away in a single day would they?

This news have been on all Swedish news channels for some days now. The issuer of this news was "The Swedish Maritime administration" Responsible for Swedish ice breaking assistance. www.sjofartsverket.se/en/Our-Activities/Winter-Navigation/"The strong winds that we have had the last couple of days has resulted in a severe ice situation, mainly in the northern part of Sea of Bothnia. This makes it hard to predict how long time each individual assistance will take." Yesterday they claimed 60 ship. Worst ice winter for 30 years. And this week did the wind pick up. Most written in Swedish but here are an article in English: www.thelocal.se/32262/20110225/These ships need ice breaking assistance. When they got assistance they are able to get away, with help. OK? More info at baltice.org

Yes, there are always ships needing assistance when there's ice in the Baltic. More so when the wind blows in the bad direction packing ice. However, what you said is plain wrong: the blue "squares" in the AIS readout are NOT ships stuck in ice. They are MOORED ships that are not planning movements at the moment. From the AIS, we will NOT know who's stuck and who's not, especially when the known congestion areas up north are not covered by AIS at all. The traffic control center will know the situation, but that's not public data. Read the relevant Wikipedia on AIS first, ok? And, news from Sweden say only "a small number" (ett fåtal) ships remained locked by ice on Sunday the 27th, so this really is a small part of the routine in the Baltic. www.sydsvenskan.se/sverige/article1397083/Is-stoppade-fartyg.html

Same article say 60 on Saturday. And on Sunday I initially wrote: "Yesterday was 60 ship stuck in ice." It is usually Saturday the day before Sunday. How it is today is another thing
I am sorry I cant see into the future.

Well the ship traffic problem was resolved in a day, in fact it appears to have been solved already before you posted.
The other problem you were having was how to read AIS correctly. Hopefully I've convinced you as to the correct nature of the various symbols?

Ice cover on Baltic Sea at widest extent since 1987 Link: www.baltic-course.com/eng/transport/?doc=37726The ice cover on the Baltic Sea is now at it widest extent since 1987, and it is expected to freeze over even more, according to Finnish meteorologists. Furthermore, warmer temperatures and high winds in coming weeks are likely to create pack ice and further problems for shipping. According to the meteorologist from Finnish news portal YLE, Toni Hellinen, the extent of the ice cover now being seen on the Baltic Sea is relatively rare, writes LETA. "It was actually last in 1987 that there was such extensive ice cover, only about once every quarter of a century is there such widespread ice. In terms of statistics we could say that the situation is rare," says Hellinen. "There is quite a lot of ice, from a few centimeters to 20 meters. The thickest ice cover is in places where ice shelves have piled up on each other and formed walls of pack ice..."
