Port calls

Two kinds of evidence, kept apart: calls Voydar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.

Behaviour at sea Voydar-derived

Patterns Voydar derived from this ship's AIS broadcasts. They are inferences, not reports: each one shows how it was computed and how confident we are, and none of them says why a ship behaved this way.
