A Bigger Ice Rink?

29.11.10 – Here’s a little science for you. Water freezes at 0°C (32°F) because at that temperature, the water molecules slow down enough to allow freezing to happen faster then melting. Now if you add salt to the water, like in the Baltic Sea which is just a couple of blocks from where I live, the temperature needs to be lower because salt doesn’t freeze and there are now fewer water molecules to do the freezing. What does this mean? It’s frig’n cold out there!

I pass by the sea pretty regularly and I wanted to get some pictures of when it was starting to freeze. You first see sections with ice where the water is kind of trapped and not open to the sea, so boat docks with closed off sections and the little strip of water which divides Katanajokka from the rest of the harbor. The temperature is dropping steadily, it’s -15°C this morning, and everything seems to be freezing now. I’ve heard from a friend who lives on the other side of town, people are already ice fishing and sledding near Arabia where there is a large inlet from the sea. I’ve also heard that the ice gets so thick, they make roads on them to drive out to the surrounding islands. Crazy.

It’s going to be awhile before I trust the ice is thick enough to walk on but I will have plenty of other pictures coming up soon.
