1. Properties of Ocean Water

2. What’s in ocean water? Minerals left behind by gases, rivers & streams
leaves elements & gases

3. What’s in ocean water?
Elements found in ocean water include:

4. What’s in ocean water? Dissolved gases are:
Nitrogen (N2) Oxygen (O2) Carbon Dioxide (CO2)
Same gases found in atmosphere

5. What’s in ocean water?
Temperature plays vital role to amount of dissolved gases in water
Cold regions have a larger amount of gases than warm regions

6. What’s Salinity?
Amount of dissolved salts present in a sample of ocean water
Described in parts per thousand

7. What’s Salinity? Salinity in various regions all differ
Range from 33 0/00 to /00
Average Salinity = /00
or rounded to 35 0/00

8. Ocean Temperature
Surface Temperature due to ocean mixing water can be heated to a depth of approx. 300m

9. Ocean Temperature
Ocean is Earth’s greatest storehouse of heat

10. Thermocline
Due to lack of sunlight at certain depths temperature can drop dramatically

11. The zone of water where temperature drops is the thermocline

12. Thermocline

13. Color of Ocean Determined by the way light is reflected or absorbed.
All colors of the rainbow are absorbed with blue being last color absorbed
Because it is the last absorbed our eyes see blue

14. If 1 kg of ocean water evaporates and 35g of salt remain the salinity is written as 35 0/00
Equator = 30oC (86oF)
Poles = -2oC (28.4oF)
