A student of mine watched an episode of "The Blue Planet" on Animal Planet that concerned the deep ocean. The next day he asked me how the ocean water could be so cold and not freeze. I assumed he meant a few degrees below celsius and began talking about freezing point depression. He asserts that the program said that the coldest ocean temperatures are -40 degrees Celsius. I cannot find any information on the web or in books to support this, but he insists that the program said -40. I think he means -4. How cold is the coldest ocean water?
