Why are the oceans blue, especially at 50 m and deeper?

What is the thermocline and why does it occur?

Where does the ocean thermocline occur year-round? Occur only in summer? Is there much fluctuation in temperature in general in the oceans?

• What forces result in the major ocean currents (gyres)? What is upwelling? How do currents affect climate?

• How does regional climate affect ocean salinity? Describe the processes. Where are oxygen levels the highest? Where are they the lowest? •

Where does photosynthesis occur in oceans?

What are phytoplankton and zooplankton?

What other life and ecological communities exist within the deep ocean environment? What might be the main food (and energy) sources for these communities?
