NOTES: Calls are by oceangoing vessels of 10,000 DWT or greater at U.S. ports, excluding Great Lakes ports. 1998 is
the first year for which data are available. Beginning in 2002, chemical tanker data are no longer reported separately
and are, instead, included in tanker data; historical data were adjusted for consistency. See Glossary for an explanation
of the vessel types.
