Definition: Sea passenger transport link
Combination of the port of embarkation and the port of disembarkation of the passenger conveyed by sea whatever itinerary is followed.
Note: These ports are maritime ports (except for fluvio-maritime transport for which they may be inland waterway ports), coded with international classification systems such as UN-LOCODE (codification for ports and other places).
Those ports can be grouped according to their geographical location by using international classification systems such as NUTS (Nomenclature for Territorial Units for Statistics - Eurostat).
Where the port of embarkation and disembarkation are the same, no sea transport link is implied.
