9. Describe the general pattern of sea surface temperatures in the ocean.
9. Describe the general pattern of sea surface temperatures in the ocean.
10. Examine the zone of warm water along the equator. Why does this zone widen to the west in each ocean (for example, the Pacific Ocean). (Hint: look at the Atmospheric Circulation Diagram and the Surface Currents Map).
The image named Kuroshio.jpg (or Kuroshio.png) shows SST measurements that illustrate the location of the Kuroshio current. The Kuroshio current is a western boundary current (it moves along the west side of an ocean).
11. What is the geographical location of the Kuroshio Current?
12. Is the Kuroshio Current a warm-water or a cold-water current?Provide a temperature range.
13. Do you see any evidence for the influence of another current? If so, what is its name and its temperature (you may refer to the Surface Currents Map).
The image named Gulf Stream.pdf uses SST to illustrate the Gulf Stream and the Labrador Currents. The two images were collected six days apart. Major currents, such as the Gulf Stream, can be compared to rivers in the ocean, and therefore transport huge amounts of water from place to place. For example, the Gulf Stream transports more than 150 million cubic meters of water per second, compared to a flow of 0.6 meters per second for all of the rivers that flow into the Atlantic Ocean.
14. What is the temperature range of the Gulf Stream Current?
15. What is the temperature range of the Labrador Current?
16. Describe what changes occur in the currents during the 6-day period between the two images. For example, notice what happens with the ring of Gulf Stream water enclosed in the colder water.
17. Describe the boundaries of the Gulf Stream. For example, are they sharp or diffuse; straight or meandering?
