There are two questions. Choose ONE to answer (I will accept the second as extra credit). Each essay should be 350 words.
Question 1: Why is the ocean layered? Explain the PHYSICAL CAUSES of layering, and describe the major layers in the ocean. Feel free to include figures. (Hint: Start with Section 4.6) Here is a figure to get you started – http://www.scienceinschool.org/sites/default/files/articleContentImages/25/ocean/issue25ocean13_l.jpg
Question 2: You are diving in a Belize sink hole (about 20-30 meters down). You cut yourself on a coral or rock and your blood appears greenish-black. Are you an alien? No … you remember your oceanography knowledge and explain to your dive buddy the reasoning to your scary blood color.
Your buddy also notices that the fish deeper in the water column are not as vibrant in color as when you started your dive in the shallow (5 meter deep) coral reef.
What explanation do you give to your buddy? (Hint: Start with Section 4.7 and following website – http://marinebio.org/oceans/light-and-color.asp)
