This is a map that shows the world's shipping lanes and the number of times a route is traveled. The routes are color coded to show how often each route is traveled in a given amount of time. This map clearly shows the amount of shipping traffic on the Atlantic Ocean but I had no idea that it was the busiest shipping lane in the world. One would imagine that the Pacific Ocean would have much more traffic due to the amount of manufactured goods coming from east and southeast Asia to North America but there are clearly more trips between the U.S and Europe. I am also very surprised at the amount of traffic in the North Sea bouncing between Germany, the Scandinavian countries, and the U.K. It is also very curious to see how islands like Hawaii can have an affect on the trajectory of shipping routes because it can be used to refill cargo ships. It is very interesting to see the trade relationships between continents.
