  1. Oceans and Seas Oceans: a belt of water circling Antarctica with 3 huge northward extensions- Pacific, Atlantic, and Indian

  2. Climate and Continents Plate tectonics drive the geographic regions of a continent such as river mouths and the size of the continental shelves Waters stores and transport heat

  3. Challenger Expedition1872 - 1875 Origin of Modern Oceanography Collected data on: • Temperatures • Ocean chemistry • Currents • Marine life • Geology of the sea floor Research vessel

  4. 3 Classes of Organisms Plankton: drifters • autotrophs 2. heterotrophs Nekton: swimmers Benthos: bottom dwellers

  5. Marginal Seas Separate coastal zones from open waters.

  6. Arctic Ocean Smallest shallowest

  7. Best Known Oceans

  8. Inland Seas, Historic Shores Strait- a narrow passage that connect two larger bodies of water. Strait of Gibralter

  9. Tethys Sea • Caspian and Aral sea are the stranded remnants of the tethys sea. • They are called endorheic because they lack a drainage outlet • They are very salty

  10. Famous Shores- Atlantic Ocean Georges Bank- broad, shallow submarine plateau. • Habitat for over 100 different species of fish. • Lucrative fishing industry for the East coast.

  11. Pacific Ocean- Western Seas Pugent Sound- Washington- a large inlet from the Pacific Ocean- usually parallel with the coast.

  12. Warm Ocean Deserts Sargasso Sea Underneath the sargassum- barren as a desert!

  13. Northern Waters of the Indian Ocean Mangrove forests support a large diversity of life.

  14. Semi-Enclosed Marginal Seas Cariaco Basin

  15. Giant Squid Data: 43 ft. long, may weigh as much as a ton. The inhabit the dark, deep regions of the oceans.

  16. Line of Life The Indonesian Archipelago has 1,700 islands. (W) Galapagos Islands (E)

  17. Galapagos Islands

  18. Eastern Pacific Barrier

  19. Southern Oscillation “ENSO” A regularly occurring climate feature that affects weather around the world= changes in the temperature of the pacific waters.

  20. Coral Reefs

  21. Coral Reefs

  22. Central Oceans: Pelagic realm

  23. Living Relics

  24. Unknown Oceans

  25. Great Southern Ocean Weddell Sea

  26. Adaptations Glycoprotein in the blood of certain fish protect them from freezing in these frigid waters. Blood antifreeze
