Modern oceanography is growing increasingly dependent upon large data-gathering capability. In particular is the use of satellites to collect data. The images are of sea-surface temperatures off the east coast of North America. We will obtain these images from the world wide web homepage for the School of Oceanography at the University of Rhode Island. This is a composite image from a number of individual images.
Warmer temperatures are in greens and yellows, cool temperatures are in other purples and blues.
Sketch the current. The yellow denotes warmer temperature, greens are immediate temperatures, blues are cool temperatures. Draw a sketch of temperature contours. From the two images, can you suggest a mechanism for the formation of warm rings and cool rings.
