Many power plants heat sea water (either for steam or cooling), I think the ocean can handle a data center just fine.

Update: I should add that I'm all for environmental study to make sure that they aren't venting it out in a sensitive ecosystem or at a radically different temp. Done correctly this can be an important development towards sustainable data centers.

We're talking about the baltic sea here. Its average depth is 55m.

Besides, it's already quite contaminated so there is a lot of environmental protection going around it.

As you can see, there really isn't places for the water to flow back and forth, so it's not a case of "the ocean is going to handle it"

Always consider the context.

Yes, but it's still a massive body of water. Local heating of the water may be an environmental issue (although a small one, I think), but heating of the entire Baltic Sea is absolutely negligible.
