Marine Vessel Traffic

About Marine Vessel Traffic

To provide users with accurate and actionable data, MarineVesselTraffic.com uses real-time filtering and analysis combined with post-processing. The chaotic raw data flow is filtered down to 30 million positions each day, one position per ship, per minute. As a rule of thumb, in-range vessels will be updated on a 60-second basis (1 position report per MMSI per minute). The Live Map (and the other website pages) update accordingly. You can pan and zoom in the usual ways, and skip back and forward in time using the timeline at the bottom of the screen. The controls at the top right let you show and hide different map layers, port names, the background map, routes (a plot of all recorded vessel positions), and the animated ships view. There are also controls for filtering and colouring by vessel type. The merchant fleet is divided into five categories, each of which has a filter and a CO2 and freight counter for the hour shown on the clock.
