The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships. Information provided by AIS equipment, such as unique identification, position, course, and speed, can be displayed on a screen or an electronic chart display and information system (ECDIS). AIS is intended to assist a vessel's watchstanding officers and allow maritime authorities to track and monitor vessel movements.
The European maritime traffic data (AIS) published by EMODnet comprises 12 categories. This vessel density analysis groups the information into 5 classes:

Dredging
Fishing
Sailing
Service
Transport

and produces the following outputs:

Yearly Vessel densities by activity type
Classification of vessel densities by activity type
Overall classification of maritime activities seen by AIS
Boxplot of the maritime activities by clusters
(hours.km-2 per month)
Yearly average vessel density 2019 by vessel types
