Short sea shipping

The modern terms short sea shipping, marine highway and motorways of the sea refer to the historical terms coastal trade, coastal shipping, coasting trade and coastwise trade, which encompass the movement of cargo and passengers mainly by sea along a coast, without crossing an ocean. 'Deep-sea shipping', 'intercontinental shipping' or 'ocean shipping' refers to maritime traffic that crosses oceans. While 'short-sea shipping' is the term used in Europe, the United States also has used the term, 'marine highway'.
