The aggregated figures are derived from the fusion of automatic identification system (AIS) information with port mapping intelligence by MarineTraffic (http://marinetraffic.com), covering ships of 1000 GT. Only arrivals have been considered to measure the total number of port calls. To produce any measurement, there must be at least 10 arrivals on a country level per commercial market made by at least 5 distinct vessels as segmented. Missing data could therefore hide small numbers of arrivals that are then also excluded from aggregates.
