Ships passing in the night
Ships over a certain size and capacity are required to have beacons that transmit the ship identification and position. This is called the AIS (Automated Identification System) and a group from the University of the Aegean in Greece is collecting this data and putting it onto a Google Map with a realtime display (default update frequency is 100 seconds).
