  1. ATMOSPHERE REVIEW

  2. Ted Talks Physical Oceanography

  3. Major Oceans • The three major oceans are : 1._______-largest, deepest, coldest, least salty. 2.__________- second largest, shallow, warm, salty. 3. _________- intermediate in depth, temperature, and salinity. • The _______Ocean near the north pole, and the ____________ Ocean near the south pole contain vast expanses of sea ice. Pacific Atlantic Indian Arctic Antarctic

  4. Methods of Studying the Ocean The Topex/Poseidon _____________ orbits 1331 km above the Earth, gathering information about the oceans. satellite Sonar _____________ maps ocean floor topography by timing how long it takes sound waves to bounce off the ocean floor. submersibles Underwater vessels called _________________ investigate the deepest ocean trenches.

  5. Sonar (also called echo-sounding) • Sound waves travel how fast in seawater? • How deep is the water if it takes ten seconds for the sound wave to go from ship to ocean floor and back to ship? 1,454 m/s 7,270 m Calculation: (10 s times 1,454 m/s divided by 2 )

  6. Bathymetric Maps: Map the topography of the ocean floor

  7. submersible • The picture below is of a _____________.

  8. Salinity The amount of salt per unit water is known as salinity. NaCl The most abundant salt in seawater is ________, but there are many other salts present in the form of ions. The average salinity of seawater is _____ ppt. Therefore, for every 1,000 ml water, there are ___ grams of dissolved salts. 35 35 Near the equator salinity is __________ than average due to ___________________. lower greater precipitation lower Near the poles salinity is __________ than average due to _______________. melting sea ice higher In the Mediterranean the salinity is __________than average due to __________. evaporation

  9. 10 Extraordinary Plants

  10. The salinity here would likely be: • 35 ppt • 34 ppt • 36 ppt

  11. Colorful Seawater • What makes the ocean water in the picture to the left different colors? • Why would a shrimp that appears bright red at the surface appear black at greater depths, and why might this be beneficial? differences in depth Longer (red) wavelengths are absorbed before reaching deep water. Shrimp can hide and not become a meal.

  12. Label the three ocean layers in the diagram below. Surface layer Thermocline Bottom layer

  13. Tides: due to the MOON Label the key with the correct tide cycle names: semidiurnal mixed diurnal

  14. Seafloor Topography H A Match the following terms to their correct letter in the diagram: B H. Island Continental shelf Continental slope Abyssal plain Seamount Continental rise Trench Guyot F A. B. E D. C F. C. D G. D E. G

  15. Surface currents: due to wind Deep ocean currents: due to differences in density (salinity) Upwelling : current that brings food (algae and plankton from the bottom of the ocean to the top of the ocean)

  16. Ocean Movements: from wind Label the wave diagram below with the following terms: wavelength, waveheight, trough, crest crest waveheight trough wavelength

  17. Listed below are some of the major surface currents. The force which generates these currents is ____________. wind

  18. El NINO: warming of the pacific ocean LA NINA: Cooling of the pacific ocean
