Unformatted text preview: after you return to your ship, you notice that there are bubbles forming in you bottle. Bubbles form because the gas in the seawater is now: A. In equilibrium with the seawater B. Undersaturated with respect to the seawater C. Overstaturated with respect to the seawater Biological Pump 6 CO 2 + 6H 2 O C 6 H 12 O 6 + 6 O C 6 H 12 O 6 + 6 O 2 6 CO O CO Surface 1500m water depth Ocean Dissolved Oxygen Draw a depth profile of the dissolved oxygen content of the North Atlantic and the North Pacific. Why are the two profiles different? If sea water has 1x10-8 H+ ions and 1x10-6 OH- ion, it has a pH of: Add Lysocline CCD Dissolution Production Amount of carbonate 1 4 3 2 5 CO 2 CO 2 Lysocline CCD Amount of carbonate 1 4 3 2 5...
