I was watching a documentary about a team that was planning to go down to the lowest point on the ocean floor somewhere in the arctic.
While the gentleman in the sub was going down, the narrator stated “at this depth, the water outside the submarine is below freezing”.
Soo… why is it not frozen? Does it have to do with the salt content in the water?
ELI5, thanks!

Salt lower the freezing point of water. In the same way that salt is used as an ice melter for sidewalks in winter.
