NOTES: Calls are by oceangoing vessels of 10,000
dwt or greater at U.S. ports, excluding Great Lakes ports. Beginning in 2002, chemical tanker data are
no longer reported separately and are, instead, included in tanker data. Historical data were adjusted for
consistency. Other includes general
cargo and combination vessels. Roll-on, roll-off vessels are especially designed to carry wheeled container trailers
or other wheeled cargo and use the roll-on, roll-off method for loading and
unloading.
