Per-port AIS activity proxy folded from NOAA MarineCadastre daily AIS files. Historical analytics, months-lagged - NOT live. Coverage is United States historical analytics. Each port carries an activity-observation count and an AIS ship-type breakdown. This serves the latest computed snapshot - port activity has no by-date dimension. Source: NOAA / BOEM MarineCadastre (public domain, CC0).
