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: 1.sodium 2.chloride 3.magnesium 4.calcium 5.potassium

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 1.Wind-driven 2.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

Coral Reefs Found in warm ocean water underwater forests Colorful RELATIONSHIPS: 1.Predator/Prey 2.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) 1.Caribbean 2.Australia 3.Hawaii Great Barrier Reef Coral: soft (alive) have polyps hard (dead) outer skeleton of limestone

200-4,000 feet down Twilight Zone 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 Complete darkness Blind/white animals Faults/trenches Pacific trench is deepest (36,198 ft down) PLATE TECTONICS: create underwater mountains, trenches, vents, volcanoes, plains
Mid-Ocean ridge: 1.Mid-Atlantic Ridge 5,000 ft above sea floor, some through island to make islands 2.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, Ocean Floors VIDEO (9 min) Podcast OCEANS VIDEO (5 min)

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)
