U.S. Vessel Traffic - Automatic Identification System (AIS)

Region(s) of Study: U.S. States and Territories

AIS data are collected by the U.S. Coast Guard through an onboard navigation safety device that transmits and monitors the location and characteristics of large vessels in U.S. waters in real time.​ This Portal allows the user to view that traffic by type of vessel (e.g., cargo, fishing, military, passenger, pleasure, tanker, tow).

Aquaculture application: The user can view patterns of vessel traffic over time to ensure that potential aquaculture development will not conflict with areas of frequent vessel traffic or coastal operations.
