Munari lecture 2 Flashcards
1
Q
What is the current amount of CO2 emissions per year?
A
2
Q
What percentage of the CO2 emissions is aborbed by oceans?
A
25-30%
3
Q
What are the results of increased atmospheric CO2?
A
4
Q
What is the classificiation of trace metals in sea water? How are they classified?
A
- Classified according to dominant inorganic ligand that complexes them
5
Q
Which metal groups will be influenced the most by changes in pH?
A
- Metals that form strong complexes with hydroxide and carbonate
6
Q
Role of free copper on speciation
A
7
Q
What are the effects of ocean acidification in estuarine environments?
A
In these areas, this situation will result in
a even greater speciation changes
8
Q
How does the shift in speciation change the solubility of metals?
A
OA could have potentially harmful effects on primary productivity by
increasing the concentration of free ionic copper,
- but acidification could also increase the concentrations of dissolved iron to stimulate primary productivity
