  1. Question of the Day Question: If you heat up a liquid, like water in a fish tank, can it hold more oxygen or less? How do you know? Answer: … … … • Turn In: • - Solubility Worksheet • p. 198 CYU 2, 3, 4, 5 • Lab: Solubility Activities

  2. Ocean Currents

  3. Two Types of Currents • Density Driven (deep water) Currents • Wind Driven (surface) Currents

  4. Density Driven Currents • Move water vertically through the ocean • Density differences cause deep water currents • Dense water sinks at the poles • Less dense water rises at the equator • This process creates circulation throughout the oceans of the world

  5. Artic Ocean Atlantic Ocean Pacific Ocean Indian Ocean

  6. Surface Currents Winds are primary energy source for surface currents. Winds blow across the ocean surface friction between the wind and the ocean surface drags the water along

  7. Which way does the water flow? Rotation of the earth changes path of air and water (Coriolis Effect) Water flows to the right (clockwise) in Northern Hemisphere

  8. Northern Pacific Surface Currents California Current Kuroshio Current North Equatorial Current Equator South Equatorial Current East Australian Current

  9. The EAC is Real

  10. Global Surface Currents

  11. Surface Currents in the US The California Current is cold and comes from Alaska The Gulf Stream is warm and comes from the equator/ Gulf of Mexico San Francisco Washington, DC

  12. What is a gyre? A roughly circular pattern of ocean surface currents Caused by the Coriolis Effect

  13. North Pacific Gyre Equator

  14. Why are gyres/ currents important? • Warm currents move heat from the equator to middle and high latitudes • Gyres influence air temperature, weather and climate of every continent
