What is Carbon Dioxide?
2
3What is Carbon Dioxide?
CO2Compound gas In its natural state
OdorlessColorless
Non-flammableFaintly acidic
4The Ocean as a Carbon Sink
How does Carbon Dioxide get in the oceans?
• Air-Sea Exchange• Natural cycle where
atmosphere-ocean give/take CO2
• Carbon Sequestration• Stop CO2 from going into
the atmosphere by injection of CO2 in the ocean
5Carbon Sequestration
6Carbon Dioxide and El Nino?
El Nino• Warming of water in the Pacific Ocean• Occurs every 3-7 years• Happens during winter
Less CO2 is being releasedThus oceans hold more of the CO2 than normal
7
8
Why?Lack of upwelling• Colder water holds
more CO2 • Warm water takes
over.• Less CO2 released to
atmosphere.
9
Why?Wildfires• Droughts in Tropics• Brush Fires• Vast amounts of CO2
released from fires
10
Does CO2 affect Ocean Currents?
• What is the Thermohaline Circulation?• Can the rise of CO2 disrupt the THC?• Effects of no Thermohaline?
Thermohaline Circulation• Largest Global Ocean Circulation• Transport heat around the world• How it works• Surface, Deep, Bottom• Affects CO2 Levels
11
12THC Affected by CO2
•Surface warming• Rising Temperatures
•Surface Freshening• Melting Ice
•“Low probability-high impact” risks•Cooling in most places in the world
Ocean Acidification
