THUNDER BAY, ON ` March 22, 2008 ~ Lake Superior News today to proud to announced that you are now able to track ships approaching the ports of Thunder Bay and Duluth using our AIS system.  You will be able to see what ships are in port and which one are moving around in the harbour. Shipping is very important to the economic well being of these two western Lake Superior communities.

Commercial vessels over 300 tons and all passenger vessels are required to have installed an AIS (automatic identification system). This equipment transmits the ships name, mmsi number, position, speed, course and heading every few seconds. AIS enables other vessels and port authorities to get an accurate overview of what is happening in their immediate area.
