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





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.
