Subtropical Gyres
Background Information
While the basic principles that lead to the formation of subtropical gyres applies to the circulation seen in each of the 5 Subtropical Gyres, there are differences that can still be seen in each of the major oceans.
Directions
Create a document that addresses the following prompt. For this assignment, you will be doing some writing and some drawing. Complete the two questions below:
- Using the image provided below, complete the following:
- Label the Northern, Western, Eastern and Southern Boundary current for each major subtropical gyre. You do not need to label the subpolar gyres.
- Color (or label) whether each of the currents are warm currents or cold currents.
- If you color them, red=warm and blue=cold
- If you would prefer to print this image and handwrite on it, you can use this document here: surface current map.pdfActions
- For this next question, choose one subtropical gyre from the question above to focus on. (North Pacific, South Pacific, North Atlantic, South Atlantic, or the Indian Ocean). In a paragraph, written in your own words, describe the circulation patterns witnessed in that ocean. Use these questions to help guide your writing:
- Are there any ways circulation differs in this ocean compared to other oceans?
- What are the unique chemical and physical properties of this ocean? Are there any unique processes that occur in this ocean? Explain
