Wired Science has posted an article showing a map of global shipping routes based on GPS data. The article is based on a study that will be published in Journal of the Royal Society: Interface. The top port in the world turns out to be the Panama Canal. The top port in the U.S. turns out to be Houston, which was a surprise to me. From the article:
The team pieced together a year’s worth of travel itineraries from 16,693 cargo ships using data from LLoyd’s Register Fairplay and the Automatic Identification System, which tracks vessels using a VHF receiver and GPS.
