WebStability in the ocean is based on the density of the water. Density must increase with depth in order for the ocean to be stable. Density is a function of both temperature and salinity, with cold salty water having a higher density than warm fresh water. Temperature and salinity in the ocean can be affected by the atmosphere. WebDensity refers to the amount of mass per unit volume, such as grams per cubic centimeter (g/cm 3 ). The density of fresh water is 1 g/cm 3 at 4 o C (see section 5.1 ), but the addition of salts and other dissolved substances increases surface seawater density to between 1.02 and 1.03 g/cm 3.

Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
