Referring to Figure 5.40, identify the primary thermal layers of the ocean, and describe their role in the thermohaline circulation. How do ice exclusion and ocean evaporation contribute to the deep ocean circulation system and how far south does this system carry the water it picks up in the North Atlantic? What is the role of deep ocean circulation in the ocean energy system?
