Much of this deep ocean water is between 0-3 degrees Celsius (32-37.5 degrees Fahrenheit)! It's really, really cold down there! There is a neat program that is measuring the temperature and salinity of ocean surface waters around the world.
In the deep sea, the ocean is dark. That is because there is a limit to the depth of ocean that light can enter. At about 656 feet (200 meters), there isn't much light, and the sea is totally dark at about 3,280 feet (2,000 meters). To some extent, the ocean also reflects the color of the sky.
