Deep Ocean Circulation: Clickable Tank
Click on the question marks to learn the temperature,
salinity, and density of the different colored water.
and salinity affect the density of the water. Cold water is
more dense than warm water. Salty water is more dense than fresh
water. When waters of different density flow in the ocean, they
order themselves from less dense near the surface to more dense
Seawater has salinities of about 35 parts per thousand (ppt)
- that is 35 grams of salt in 1000 grams of seawater, but it
Fresh water has a density of 1 gram per cubic centimeter (g/cc).
Seawater has very slightly higher densities of about 1.02-1.03
grams per cubic centimeter. Even though these are very small
differences, they are enough to drive deep ocean circulation.
