  1. Introduction to the Marine Environment 3/18/12

  2. What is water? • H2O • Cohesion properties • Surface tension due to hydrogen boding

  3. What are the factors that affect currents and tides? • 1) Heat (solar) • 2) Salinity • 2) Wind (atmospheric interaction) • 3) Gravity (moon alters tides) • 4) Coriolis effect

  4. What is salinity? • The dissolved particles in water (i.e. Salt)

  5. What is temperature?

  6. What are ocean currents and waves?

  7. What is upwelling? • Cold, nutrient rich water brought to the surface, as warmer waters move away from the land.

  8. How do temperature and salinity affect ocean currents? • Increased Temperature = increased volume • Decreased temperature = holds more solutes (more dense)

  9. What are thermohaline circulation patterns? • Currents dependent on temperature and salinity transporting enormous volumes of cold, salty water from the North Atlantic to the Northern Pacific, and bringing warmer, fresher water in return.

  10. What is the current along California? • Cool current, flowing south

  11. What is the Coriolis effect? • Earth’s rotation on its axis causes winds not to travel straight http://www.youtube.com/watch?v=mcPs_OdQOYU

  12. How does the gravity of the moon affect the tides?

  13. What is El Nino?
