C Sequestration

• what is carbon sequestration?


  a natural or artificial process by which carbon dioxide is removed from the atmosphere and held in a solid or liquid form
• what do the oceans play an important role in?

  Regulating the amount of carbon dioxide in the atmosphere
• Why do the oceans play an important role in regulating the amount of carbon dioxide in the atmosphere?

  CO2 can move quickly into and out of the oceans
• What does CO2 once IN the oceans?

  No longer traps heat
• How does CO2 move between the atmosphere and the ocean?

  By molecular diffusion when there is a difference between CO2 gas pressure (pCO2) between the atmosphere and oceans
• What does CO2 do when the atmospheric pCO2 is higher than the surface ocean?

  CO2 diffuses across the air-sea boundary into the sea water
