Lecture 21: Carbonate chemistry Flashcards
1
Q
What is Gas solubility in the ocean dependent on?
A
Gas solubility is dependent on salinity and temperature
2
Q
What happens to solubility when salinity increases?
A
Solubility decreases with increasing salinity
3
Q
What happens to solubility when temp increases?
A
Solubility decreases with increasing temperature
4
Q
How does CO2 behave in sea water?
A
CO2 in seawater behaves as a weak acid
5
Q
How can the carbonate system be described?
A
The carbonate system can be described by knowing dissolved inorganic carbon (DIC) and total alkalinity (AT)
6
Q
Difference between Ocean acidification / Ocean alkalinisation?
A
Simple
7
Q
How much CO2 emitted by humans since 1800 has been taken in by the ocean?
A
The ocean has taken up ~30% of all the CO2 that has been emitted by humans since the 1800s
