Deep ocean water

Deep ocean water is water that is found way down in the ocean, near the bottom. It's really cold and really dark because it's so deep and there isn't much light down there. The ocean is also really deep, much deeper than land and much deeper than swimming pools. Lots of creatures live in deep ocean water, like fish and whales and turtles, and some of them are really amazing and weird-looking! Scientists also go down deep in the ocean to study different things.
