Oceanography

And related materials

food chain begins with
Food chain begins with:
  • Algae
  • Phytoplankton (plant plankton)
  • Other plants
mid ocean ridges
Mid-ocean ridges
  • They are all divergent boundaries (spreading apart)
sargasso seaweed
Sargasso Seaweed
  • Seaweed that sea turtles live in, in the middle of the Atlantic
primary consumers
Primary Consumers
  • Zooplankton (animal plankton)
  • Krill
salinity
Salinity
  • Salinity = saltiness
  • Ocean water is 96.5 parts pure water, with 3.5 parts (or %) salts.
  • Salt ions= calcium, chlorine, sodium, potassium, etc.
depth
Depth
  • Deeper you go:
    • Saltier it gets (its more dense)
    • Colder it gets (less sunlight)
    • Higher pressure
  • Most plankton and corals close to surface, bc they need sunlight. Why?
upwelling
Upwelling
  • The process that brings nutrient rich water up from the deeps.
  • These nutrients power plankton
  • It can provide more Calcium, which oysters and shellfish use to make their shells

Crest-top of wave
  • Trough-bottom of wave
  • Period-distance between waves
oceans
Oceans
  • Largest:
  • 1. Pacific
  • 2. Atlantic
  • 3. Indian
  • 4. Antarctic
el nino
El Nino
  • This occurs every 4-5 years, when a warm ocean current in the pacific reverses course (for some unknown reason).
  • This affects weather all over the globe.
