Marine Traffic Google Mashup

MarineTraffic.com have produced a Google Map showing real-time information about ship movements throughout the world.

The system is based on AIS (Automatic Identification System). The International Maritime Organization (IMO) requires all vessels over 299GT to carry an AIS transponder on board, which transmits data on position, speed and course, among some other static information, such as the vessel’s name, dimensions and voyage details.
