Data & citation
Transit counts are gate-line crossings computed hourly from ChartNav's own live AIS network (terrestrial receivers; coverage varies by zone — the coverage figure above says how complete the picture is, and reporting gaps are only flagged for vessels that were underway and stopped reporting globally). Baselines are rolling medians of complete days. Numbers may differ from weekly satellite-AIS datasets such as IMF PortWatch, which lag by several days but see areas terrestrial receivers cannot.
