Across
  1. 5. The study and exploration of the world's oceans
  2. 8. Animal-like component of plankton that feed on plankton and other zooplankton (primary consumers) (think ANIMALS belong in a ZOO)
  3. 9. The amount of dissolved salts in seawater
  4. 14. filter Living organisms (plants & animals) that "clean" water through natural processes [ex. oysters filter out water as they eat collecting contaminants in their bodies]
  5. 16. factor Non-living factors of the environment that an organism lives in (ex. sun, water, air, soil)
  6. 17. The farming of saltwater and freshwater organisms (i.e. shrimp farms)
  7. 19. a process used by some bacteria in the ocean to generate energy with methane and hydrogen sulfide
  8. 22. A ring-shaped coral reef that surrounds a shallow lagoon
  9. 23. The production of non-thermal light by creatures converting chemical energy to light energy to lure prey, attract a mate, or assist in keeping a species together. ~75% of creatures glow.
  10. 27. slope The steep incline between the continental shelf and the abyssal plain; also thought of as the "true" edge of the continent
  11. 28. zone 1000 to 4000m; higher pressure, dense water, cold, fewer animals, no light
  12. 31. National Oceanic and Atmospheric Administration
  13. 32. Not having light; darkness
  14. 33. vent An opening in the sea floor where super-heated water, gases, and other nutrients are released into the surrounding seawater
Down
  1. 1. Having light
  2. 2. Sound NAvigation Ranging - used to measure ocean depth by sending sound to bounce off the ocean floor
  3. 3. (deep) zone Extends from 6000m deep to the bottom of the ocean; very few animals; temperature near freezing; high pressure
  4. 4. spreading A process by which new rock is added to the ocean floor along the boundary of diverging plates
  5. 6. Extends past the sunlight zone
  6. 7. zone 4000 to 6000 m; no light; crushing pressure, very cold and salty; few animals; sea cucumber and tube worms
  7. 10. Free-swimming organisms move all through the water column and are independent of the tides, currents and waves
  8. 11. zone 200 to 1000m; dim light, denser water, more pressure
  9. 12. A volcanic peak that rises at least 3280 ft (1000 m) from ocean floor
  10. 13. factor The living organisms of the environment
  11. 15. zone The area that lies between the low-tide and the high-tide line
  12. 18. Body of water where fresh water meets saltwater
  13. 20. The deepest parts of the ocean. The deepest one is the Marianas Trench (located in the S. Pacific Ocean - almost 5 miles deep)
  14. 21. The movement of cold water upward from the deep ocean that is caused by wind. This brings up tiny organisms, minerals & nutrients to come from deepest parts of ocean
  15. 24. zone The first 200m of ocean water that extends outward from shore and covers most of the continental shelf; warm, much light, diverse with plants and animals
  16. 25. ridge A chain of undersea mountains that circles the Earth through every ocean
  17. 26. shelf Extends from the edge of the continent outward to where the bottom sharply drops off into a steep slope
  18. 29. Tiny algae and plants that float in water and are carried by waves and currents. They MAKE their own food. Phyto (think PHOTOSYNTHESIS)
  19. 30. Organisms that live on, near or in the ocean floor
  20. 34. Microscopic algae with plate-like structures composed of silica
