1. Properties of Ocean Water

2. Chemical Properties of Ocean Water
Determines composition
Enables it to dissolve other substances

3. Physical Properties of Ocean Water
Temperature
Density
Color

4. Elements in the Ocean Chlorine Sodium Magnesium Sulfur Calcium
Potassium

5. How do these elements get into the ocean
Rivers deposits are carried to the ocean
Evaporation of ocean water leaves minerals behind

6. Dissolved Gases
Nitrogen
Oxygen
Carbon Dioxide- most easily dissolved

7. Temperature Influences how substances dissolve in water
Solids dissolve better in warm water
Gases dissolve better in cold water

8. Temperature
How does temperature of water influence the composition of ocean water?

10. Surface Temperature Infrared rays heat the water
Mixing of water distributes the heat down to about 300 meters
Depends on the latitude

11. Thermocline
The point at which the temperature of ocean water drops dramatically
Less dense warm water can not mix with dense, cold water

12. Density Factors Salinity Temperature
More dissolved solids = More dense
Temperature
More dense = cold
Less dense = warm
