  1. Final Review Oceanography

  2. Scientific Method • Techniques to investigate phenomena • Steps: • Ask a question • Research • Hypothesis • Analyze data • Conclude

  3. Scientific Method • Independent variable • Dependent variable • Control • Constant

  4. History of oceanography • What did ancient people have knowledge of? • What limited them? • What was the Challenger Expedition? • Why was it so important to the field of marine biology? • When did scientific inquiry come to a stand still

  5. What are the 4 major oceans • Atlantic, Pacific, Indian, Arctic • What are characteristics of each

  6. Ocean floor • Ridge vs. Trech • Subduction vs. Sea Floor spreading • Continental margin • Magnetic banding patterns

  7. Continental drift theory • What is it? • What evidence is there that it happened.

  8. Surface Area • Large organisms vs. small organisms surface area to volume ratio • Advantages of having a large SA/V ratio

  9. Reproduction • Sexual vs. Asexual reproduction • Mitosis vs. Meiosis

  10. Gyres • Wind patterns- Trade winds • Pacific Garbage Patch

  11. Tides • What is the difference between spring tides and neap tides?

  12. Macromolecules • Protein • Nucleic Acid • Lipids • Carbohydrates • Monomers of them are…

  13. ATP • What is ATP ? • Why is it important?

  14. Photosynthesis • What goes in? • CO2 + H2O  C6H12O6 + O2

  15. Respiration • C6H12O6 + O2  H2O + CO2 • Anaerobic vs. Aerobic

  16. Marine fish vs. freshwater fish • Osmosis how does it affect these fishes?

  17. Osmosis • Hypotonic • Hypertonic • Isotonic

  18. Passive Transport vs. Active transport • What is the difference? • What is an example?

  19. Levels of organization • Cell • Tissue • Organ • Organ system • Organism • Population • Community • Ecosystem

  20. Phylums and classes MATCHING MATCHING Class of echinodermata “sea lillies” Stinging animals Sponges Valvled animals well represented throughout geologic time Comb jellies Spoon worms Segmented worms Feed with a lochophore and burrow in sediment Sponges Peanut worms Moss like animals • Cnidarians • Ctenophores • Annelida • Phoronids • Proifera • Sipuncluans • Echiurans • Bachiopods • Bryozoans • Echinodermata • Crinoids

  21. Anatomy

  22. Anatomy

  23. Whales • Toothed walesvs baleen whales • ID methods

  24. Zones of the ocean • Intertidal • Subtidal • Pelagic • Mesopelagic

  25. Estuary • What are the 4 types of estuaries • What is NC?

  26. El Nino • Trade winds become weaker • Warm water spreads across to Eastern side of Pacific Ocean basin • Upwelling decreases

  27.  The little things  • Diatoms • Dinoflagellate • Radiolarians • Cilliates • Foraminifera
