Chlorophyll & Sea Surface Temperature

Mini Lesson

Virtual Teachers:  Make a copy of the Google Forms LogoGoogle Form of your choice so that you may assign it directly from your Google Drive into your Learning Management System (e.g., Google Classroom, Canvas, Schoology, etc.).  Do you need help incorporating these Google Forms into your Learning Management System?  If so, read this google doc logo Guide to Using Google Forms with My NASA Data.

Directions: 

  1. Analyze the Chlorophyll Concentrations color bar legend provided.  Describe what the color bar legend represents.

  2. Describe where you observe the highest concentrations? Lowest? 
  3. What factors do you think control where phytoplankton are distributed?
  4. Now, analyze the Sea Surface Temperature mapped image, paying specific attention to the color bar provided and answer the following questions.

    1. Where do you observe the highest concentrations? Lowest? 
    2. What do we call the waters that are found here? 
  5. Review following video visualizing Chlorophyll & Sea Surface Temperature from 2002 to 2019.
     
  6. Answer the following questions:
    1. Where are the highest concentrations of chlorophyll generally located? Do the trends that you observed in the Northern Atlantic also occur in the Southern Hemisphere?
    2. How do the values of chlorophyll change over the seasons? 
    3. Why do you think that the polar regions experience these changes during the spring/summer seasons?
