Will sharks freeze to death in the Arctic Ocean?

Generally sharks don't freeze to death because they are in the deep sea. If the sea is shallow, it will freeze quickly. What about the deep sea? It only freezes on the top layer of ice, so the ice is more than a foot thick, at most two feet. This shark is in the North Sea. Although it was too cold and the weather was cold, the air dropped, so I didn't see him move, because he would live under the deep sea. I think it is impossible for sharks to freeze to death in the North Sea.
