1- In terms of sunlight and commercial fisheries, what isthe difference between the Surface Ocean (Euphotic Zone),Twilight Zone (Mesopelagic Zone), and Deep Ocean (AphoticZone)?

2. (2 pts) Which general areas of the ocean are acting as
CO2 sources (carbon dioxide is moving from the ocean to the atmosphere)?

3. (2 pts) Which general areas of the oceans are CO2 sinks (carbon
dioxide is moving from the atmosphere to the ocean)?
4. (1 pt) Are areas where Deep Water forms sources or sinks of
CO2 ?
5. (1 pt) Based on what you see on the Map, does more CO2
dissolve in colder surface waters or warmer surface waters?
6. (1 pt) Sea surface waters have become warmer as the climate
warms. If this continues, would you expect concentrations of
CO2 in the atmosphere to decrease or increase?7. (1 pt) What do diatoms build their ‘houses’ out of?
8. (2 pts) How are carbonate ions from the Ocean Carbonate
Chemistry system connected to the Biological Carbon Pump?
9. (4 pts) Take a breath and exhale. Describe how carbon atoms
from the CO2 you exhaled could end up in the shell of an organism
such as a lobster or clam.
10. (2 pts) When shell–builders die and sink in the ocean what are
two possibilities for what will happen to their shells?
11. (2 pts) Considering what you learned in the Deep Sea Sediments
Lab, what are two things that the shells of microscopic plants and
animals (phytoplankton and zooplankton) can tell scientists about
past climate?
12. (2 pts) Considering the Ocean Carbonate System and what you
learned in the Ocean Acidification Lab, an increase in atmospheric
carbon dioxide is causing an increase in what ion in the world’s
oceans? How is this affecting organisms that build shells?
