  •  
    • Ocean Notes
    • Salt water/ salinity
    • 360 million square miles
    • 3.5 billion years old
    • 100,000 + species
    • 28 degrees to 86 degrees F
    • 7 miles down in some places
    • Mineral composition:
      • sodium
      • chloride
      • magnesium
      • calcium
      • potassium

  • Ocean Currents Coriolis Effect http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fw/gifs/coriolis.mpg Video explanation
  • Sunlit Zone www.ngdir.ir/sitelinks/kids/html/en-water.htm
    • Currents (trade winds): underwater rivers
    • Warm water moves up, Cool water sinks down
    • in a circular motion.
            • Gyres : circular patterns the wind moves the currents.
    • Gyres : circular patterns the wind moves the currents.
    N __________ S
    • Wind-driven
    • Thermohaline
    • Influences Climate Summary
    • Summer Ocean stores heat
    • Winter Ocean releases heat
    • Currents carry off excess heat from tropical oceans to polar oceans
    • Warming polar oceans (GLOBAL WARMING)
    • MAJOR source of precipitation
  • Ocean Currents Coriolis Effect http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fw/gifs/coriolis.mpg Video explanation
    • CURRENTS: Highlight on your map:
    • N. Equatorial
    • S. Equatorial
    • California Current
    • Canary Current
    • Gulf Stream
    • Japan Current
    • Labrador Current
    • Peru Current
    • El Nino
    • Antarctic Circumpolar *Strongest
  • http://www.enchantedlearning.com/coloring/oceanlife.shtml
  • Sunlit Zone
    • Depth: 400-600 ft.
    • Coral reefs
    • Plankton/ photosynthesis
    • Currents (trade winds): underwater rivers
    • Gyres : circular patterns the wind moves the currents.
  • Sunlit Zone Plankton pics Zooplankton pics http://ebvgroup4.wikispaces.com/file/view/seagrass_role.jpg/70547843/seagrass_role.jpg http:// i.ehow.com/images/a06/8h/bt/euphotic-zone_-200X200.jpg

  • Scuba Gear
  • Coral Reefs
    • Found in warm ocean water
    • “ underwater forests”
    • Colorful
    • RELATIONSHIPS:
    • Predator/Prey
    • Simbiotic
    • Diversity: 2 nd most productive habitat (following mangroves & rainforests
    • Endangered
  • Coral Reefs
    • Found on EASTERN coasts of Continents (because of the warm, strong currents)
    • Caribbean
    • Australia
    • Hawaii
    • Great Barrier Reef
    • Coral: soft (alive) have polyps
    • hard (dead) outer skeleton of limestone
  • Coral Reefs
  • Twilight Zone Enchanted learning.com
  • Twilight Zone
    • 200-4,000 feet down
    • Sunlight barely gets through the water: Hard to see, not dark, not light (like dawn and dusk above water)
    • Large predators: sharks
    • Below the continental shelf, at the drop-off zone
  • Midnight Zone http://www.pbs.org/saf/1207/images07/life2.gif http://www.itsnature.org/wp-content/uploads/2008/02/giant-clam2.jpg http://www.eyezed.com/wp-content/uploads/2009/09/angler-fish.jpg http://ldtstudio.coe.uga.edu/mod/glossary/view.php?id=2392 http://www.life.com/static/ugc/022/ugc1001022/watermarkcomp.jpg
  • Jimmy Suit http://my.fit.edu/~swood/images/tether10.jpg
  • Midnight Zone
    • Complete darkness
    • Blind/white animals
    • Faults/trenches
    • Pacific trench is deepest (36,198 ft down)
    • PLATE TECHTONICS: create underwater mountains, trenches, vents, volcanoes, plains
    • Mid-Ocean ridge:
    • Mid-Atlantic Ridge 5,000 ft above sea floor, some through island to make islands
    • Through 3 oceans
    • Along ridges are HOT vents (black smokers)
    • -Copper, iron, sulfur, zinc flow out
    • -Strange marine life
    • -Special bacteria use chemicals & heat to make food
    • -1 foot giant clams
    • -giant red tube worms, crabs, blind or glowing fish
    • Abyssal Plains :
    • Ooze, sediment
    • PLATE TECTONICS
    • Trenches:
    • Seamounts: volcanic activity with the mountains,
  • Intertidal Zone http://1.bp.blogspot.com/_I_A_unRXfEw/TQGZ6hODDAI/AAAAAAAAAdE/HAJ0a0C3PU4/s1600/lowtide3.jpg
  • Intertidal Zone
    • On the beaches
    • Unstable, saltier, waves disturb it
    • Tides : cycles of rise and fall of ocean’s surface due to moon’s gravitational pull
    • The tides pull out leaving tidal pools with organisms still in it, awaiting the next high tide.
    • - Low tide : organisms exposed to air
    • - High tide : organisms under ocean water
    • High tide zone: exposed to more air, more low tide
    • (sea anemones, barnacles, crabs, mussels, sea stars, snails, whelks…)
    • Middle tide zone: exposed to equal amounts of air and water with the tides
    • (seaweed, sponges, shrimp, krill, zooplankton…)
    • Low tide zone: exposed to more ocean water
    • (BIODIVERSITY: hydroids, crabs, abalone, surf grass, tubeworms)
  • Ocean Tides: High tide Low tide http://blog.lib.umn.edu/lieb0116/architecture/2006/10/the_changing_tides_phenomenon.html
