      • 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 Exploration:

    • 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

    • Sunlit Zone
      • Depth: 400-600 ft.
      • Coral reefs
      • Plankton/ photosynthesis
      • Currents (trade winds): underwater rivers
      • Gyres : circular patterns the wind moves the currents.

    • 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
