Presentation Transcript

  1. Oceanography And related materials

  2. Food chain begins with: • Algae • Phytoplankton (plant plankton) • Other plants

  3. Porifera

  4. Mid-ocean ridges • They are all divergent boundaries (spreading apart)

  5. Sargasso Seaweed • Seaweed that sea turtles live in, in the middle of the Atlantic

  6. Primary Consumers • Zooplankton (animal plankton) • Krill

  7. @ Top of the Food Chain: • jaws.mp4

  8. Narwhal

  9. Salinity • Salinity = saltiness • Ocean water is 96.5 parts pure water, with 3.5 parts (or %) salts. • Salt ions= calcium, chlorine, sodium, potassium, etc.

  10. Depth • Deeper you go: • Saltier it gets (its more dense) • Colder it gets (less sunlight) • Higher pressure • Most plankton and corals close to surface, bc they need sunlight. Why?

  11. Upwelling • The process that brings nutrient rich water up from the deeps. • These nutrients power plankton • It can provide more Calcium, which oysters and shellfish use to make their shells

  12. Ocean currents

  13. Crest-top of wave • Trough-bottom of wave • Period-distance between waves

  14. Ocean floor

  15. Oceans • Largest: • 1. Pacific • 2. Atlantic • 3. Indian • 4. Antarctic

  16. Why does ice float?

  17. El Nino • This occurs every 4-5 years, when a warm ocean current in the pacific reverses course (for some unknown reason). • This affects weather all over the globe.
