12 Nike Shoe Investigation ANALYSIS OF DATA:1- Define these terms: (a) gyre:a large system of rotating ocean currents (b) current: a continuous, directed movement of ocean water generated by the forces acting upon it, (ie: gravity, salinity, etc.) (c) eddy: the swirling of a fluid and the reverse current created when the fluid flows past an obstacle.2- By looking at the data you plotted on your map, write a sentence or two describing the general shape of the route or pathway taken by the drifting shoes. The path of the shoes was in a circular, rotating motion such as a current.3- Write a few sentences EXPLAINING this pathway using appropriate terms from #1 above. The shoes followed the North Pacific Current, which is part of a gyre. The path of the shoes went in a circle because the current rotated in a circle, starting off the coast of Asia, going to Alaska, halfway down the coast of American West Coast, and circling through the ocean and Hawaii, and back to Asia.
13 Nike Shoe Investigation (contd.) 4- Using an atlas or other reference showing the major surface currents in the Pacific Ocean, (a) List the names for each of the currents that affected the distribution of the shoes, and: The North Pacific Current, California Current, North Equatoral Current, and Kurishio Current. (b) write them on you map showing their correct location.
14 Extra Credit5- Using a more detailed map or an atlas showing the Pacific Ocean with a distance scale, calculate approximately how far the shoes traveled between the point where they spilled and their first landfall. The shoes likely went about a thousand miles before they reached landfall.6- Considering the distance you figured in #5, and the time it took for the shoes to make their first landfall, (a) What was the speed of the current moving those shoes in kilometers per day? (b) miles per day? (c) kilometers per hour? (d) miles per hour?7- Calculate approximately how far the shoes traveled between California and Hawaii.
15 Extra Credit (contd.)8- Considering the distance you figured in #6, and the time it took for the shoes to move from California to Hawaii (a) Whatwas the speed of the current moving those shoes in kilometers per day? (b) miles per day? (c) kilometers per hour? (d) milesper hour?9- Name the two surface currents you have been studying in the above questions.10- Based on your calculations, rank the two surface currents according to their speed.11- Based on the average speed of the two currents, how long would it take for plankton drifting off the coast of San Francisco reach Santa Monica Bay
