After completing the lesson, the learner will be able to do the following:
- Describe the observed and projected records of atmospheric CO2, oceanic dissolved CO2, and ocean acidity (pH).
- Describe the chemistry of ocean acidification with respect to calcium carbonate minerals calcite and aragonite
Describe the marine carbon cycle
Describe the impact of increased CO2/acidity on the distribution and abundance of calcifying organisms (e.g., plankton, algae, coral, mollusks, echinoderms)
- Describe ecological impacts independent of calcification, including effects on reproduction and behavior, and ecosystem shift
Describe the impact of increased CO2/acidity on green algae
Describe the prehistoric record of climate and ocean acidity (pH) and its relation to mass extinction events
