   1.Sensitive satellite instruments can detect different colors in the ocean which can
       reveal the presence and concentration of what?
   2.Why do phytoplankton appear as different colors to the sensitive satellite
       instruments?
   3.What does SeaWiFS stand for?
   4.Why are phytoplankton so important?
   5.Why would a fisherman be interested areas of high phytoplankton concentrations?
   6.How can ocean currents effect phytoplankton?
   7.Explain the role that phytoplankton play in the "Carbon Cycle".

Questions: (Lesson 8 - SeaWiFS Data Directions and Questions)

SeaWiFS Browser:
Choose your current month from the selection below the global picture.  This will give you
averaged results for an entire month's data.  **If you are at the beginning of a month, you
may choose the previous month's data for a better image.

Click on the color bar on the right-hand side of the global picture.
        1.What are the units that chlorophyll is measured?
        2.What color designates the highest concentration of chlorophyll?
        3.What color designates the lowest concentration of chlorophyll?

        1.Generally speaking, what regions show the highest concentration of chlorophyll?
        2.Generally speaking what regions show the lowest concentration of chlorophyll?
        3.In the North Atlantic Ocean, do concentrations of chlorophyll increase or diminish
           as you go from the equator to the North Pole?
        4.Therefore, in general, do colder or warmer waters contain higher concentrations of
          chlorophyll?
        5.Explain how the Gulf Stream will affect concentrations of chlorophyll.
        6.What are the chorophyll concentration in the middle of the North Atlantic Ocean?

Questions: (Lesson 8 - SeaWiFS Data Directions and Questions)

        1.In the Gulf Stream Region, how does Sea Surface Temperatures compare to
           chlorophyll concentrations?
        2.Can you hypothesize why higher chlorophyll concentrations occur in coastal
            regions regardless of sea surface temperature?
