Daily Study Questions distributed during lecture are designed as test study-guides.
Other Questions to Consider: 1. Why are the seas salty? 2. Why are some ions present in sea water in high concentrations, while others are present only in low concentrations? 3. Explain the vertical distributions of phosphate and nitrate. What is a limiting nutrient? 4. What processes affect seawater density? Explain the formation of deep water around Iceland and Antarctica. 5. Describe (and be able to diagram) atmospheric circulation patterns during a normal year, an El Niño year, and a La Niña year. 6. What happens to Sea Surface Height, the Thermocline and the Water Temperature during an El Nino & La Nina. 7. Explain the formation of the oceanic gyres. Why do currents on the eastern and western boundaries of these gyres have different characteristics? What are the currents in the North Atlantic and North Pacific Gyres? 8. What causes the extensive upwelling off the coast of Peru? (Refer to surface current patterns, coriolis force, and Ekman transport.) What is the effect of this upwelling on local fisheries? 9. Why is the ocean blue? 10. At what depth does a wave begin to “feel the bottom?” 11. How would you determine the speed of a wave in deep water? In shallow water? 12. Draw the 4 major ocean currents that compose the gyres in the North Pacific. Now draw the 4 major ocean currents that compose the gyres in the North Atlantic.
