Since early November, the number of vessels sending the Automatic Identification System (AIS) signal from seas around China plunged by 85 percent. On Oct. 28, more than 100,000 ships were broadcasting but, according to global shipping data provider VesselsValue, by Nov. 17, only 15,000 were broadcasting the signal.
The Automatic Identification System (AIS) is an international standard for ship-to-ship, ship-to-shore, and shore-to-ship data communication approved by the International Maritime Organization (IMO).
