Wild Card
100
This is the sea zone extending up to 200 nautical miles from a nation's coast. The nation holds special sovereign rights to explore, exploit, conserve, and manage natural resources - such as fish, oil, gas, and renewable energy - within this area.
Exclusive Economic Zone

This tool allows you to create a running "notification" when certain criteria is "triggered"
Alerts
100
Toggling this can show a ship's past movements
History Trail
100
Automatic position reporting system that uses transponders on ships and is used by vessel traffic services (VTS). This is the "backbone" of the vessel data available in SeaVision.

Name the two primary methods of AIS data *collection* (meaning, where is the data received)
Terrestrial (on land) and satellite.
