A
Biological
Carbonate
Physical
2
Q
How much carbon does the Ocean store?
A
38,000 Gt
3
Q
What is the Biological pump
A
Phytoplankton storing carbon
4
Q
What is the Physical Pump
A
Dissolved carbon being transported across the ocean via the thermohaline circulation
5
Q
What is the carbonate pump
A
Calcium carbonate shells and bones of marine organisms.
6
Q
Why is global warming bad for the ocean
A
Glacier melt
- Sea level rise
Thermal expansion
Releases carbon
- Phytoplankton death
- Altered thermohaline circulation
- Deteriorating calcium carbonate shells and marine life
7
Q
Geological processes releasing carbon
A
Fracking
Outgassing
Chemical weathering
Resource abstraction
