These control what is shown on screen, both in the ‘Map view’ and ‘List of vessels’ screens.
This area displays the result of the filters. If a vessel is selected its details are shown in this area.
These move the map in and out. The zoom shortcut is a double click on the map to zoom in, and hold shift + double click to zoom out.
This allows you to find vessels by unique vessel details (MMSI, name, call sign). The latest location of that vessel is shown by default.
These are shown as icons with their past tracks on the map. Select a vessel to view its details. To view the details of multiple vessels, hold shift + click on them.
This is signified by a grey hexagon with a download arrow. This occurs in areas where there are many vessels, like a port. We do this to make Starboard faster. To see vessels in this area, click on the hexagon and vessel information will load.
The grey lines are the exclusive economic zones (EEZ) of all nations. The grey lines around Aotearoa New Zealand are the 12 and 24 nautical mile lines. The shaded grey areas near Aotearoa New Zealand are marine protected areas.
This shows the range selected in the ‘Time’ filter. Drag the time slider back and forth to move the vessels through time. Tap your arrow keys to move the time slider in 10 minutes increments, and hold shift + tap to move it 1 hour.
Clicking ‘Track history’ at the bottom of the vessel details panel displays an annotated track history. Each noteworthy event is recorded against a vessel. Click on any event to jump to it.
Shown as a pink line. This signifies when Starboard believes a vessel is fishing. This activity is detected by an algorithm, as opposed to being reported by the vessel.
Shown as a dashed line. Missing AIS data means a vessel has not been transmitting its AIS locations for more than 4 hours.
Shown as a dark blue line. Loitering means a vessel has travelled at less than 2 knots for at least 4 hours. This slow movement is consistent with the behaviour observed when two vessels meet at sea, or a vessel is waiting to enter port.
Shown as a dark red line and double red line icon on selected vessels. Encounters mean two vessels (or sometimes a vessel and a buoy) have met with the following criteria: either they’re less than 50 meters from each other for at least 10 minutes, or less than 200 meters from each other for at least 30 minutes. This movement is consistent with the behaviour observed when two vessels meet at sea to exchange goods—fuel, fish, people or cargo, for example.
Shown as a dotted circle. Similar to encounters, a rule applies (less than 2 knots for more than 4 hours) except here the vessel is not transmitting AIS locations. As such we don’t know what it was doing during this period of time, but it was likely travelling very slowly.
Everything on the screen responds to the filters you have set. These are set at the top of the screen.
The above view shows the analysis of vessels heading towards Aotearoa New Zealand for their relative Covid-19 risk, with these filters:
Filters can be changed to study a small area over a long timeframe. The above view is an example of this and shows analysing vessels in North Minerva Reef over 9 months. To recreate this view:
A list can be generated for all of the vessels you can see on the map, at any given time. (Sometimes vessels just outside your monitor’s viewport are included). From here you can:
In the ‘Covid-19 risk’ analysis type vessels are coloured yellow, orange, and red in relation to their relative risk profile. More about Covid-19 risk assessment.
In the ‘Hitchhiker pest risk (BMSB)’ analysis type vessels are coloured dark blue and red in relation to their relative risk profile. More about BMSB risk assessment.
In the ‘All activity’ analysis type fishing vessels are pink, all others are white. Fishing activity is always pink.
Click on any vessel to bring up its details. Clicking on ‘Track history’ shows its past movements and the ‘Vessel report’ displays time at sea vs in port, past movements, and further vessel details.
