Norwegian waters — live vessel traffic

A live map of vessel traffic in Norwegian waters — the mainland's economic zone, the Svalbard and Jan Mayen zones, and the Barents Sea out to the Russian line.

Status: live. The vessels are BarentsWatch's open AIS feed, fetched once a minute by a Novem job and shown 75 s behind real time. If the feed stops, the map says Feed paused, and as the last update ages, ships that were under way turn into lost-contact rings.

How to read it

• Darts are ships under way, pointed along their course; dots are moored, at anchor or still; hollow rings are ships last heard under way that have been silent for 30 minutes or more. Ships that go quiet while moored or at anchor fade instead.
• Ships move between real position reports: the map runs 75 s behind real time, so it can place each ship between two reports instead of guessing. After its newest report a ship is dead-reckoned for at most 10 minutes, then held.
• Trails show the last hour and fade with age; dotted stretches are silences of 45 minutes or more.
• A ship on an official sanctions list has an outline — white on the dark map, black on the light one — matched by the IMO number it broadcasts against the EU, UK and US lists. Click On a sanctions list in the legend to show only those ships.
• Click a ship for its own view: its last 24 hours (where it stopped, when it was not heard, what it changed in what it broadcasts); for a listed ship, what each list says of it — the name and flag it is listed under, the owner or company the list names, its reason in the list's own words; its last port calls; and what open registers say of it. Zoomed in close, ships are drawn to scale.
• The legend is also a filter: click a vessel type to hide or show it. Cables, pipelines and military areas are under Key and layers. Svalbard is shown in an inset. To zoom with the scroll wheel, click the map first or hold Ctrl/⌘.
• The shaded sea is outside what the open feed covers. Fishing-gear buoys and search-and-rescue aircraft also send AIS; they are left out.

Facts, not verdicts. Everything shown is what a source states, with its date. A listing is never inferred and an absence from a list is never claimed. Port calls are Global Fishing Watch's reading of AIS worldwide, about three days behind: a ship's past, not where it is. Owners are named only when they are companies; private persons are not.
