Note: "Deep sea water" as a single mode describes shipments moving only on the
open waters of the oceans or the Gulf of Mexico.  Most shipments moving
primarily on the open ocean are tabulated under "Inland water and deep sea".

1.  Average miles and ton-miles are based on the estimated distance traveled,
not on Great Circle Distance.  Calculation of average miles per shipment
excludes shipments of STCC 27, Printed Matter. See the "About the Mileages"
section of the Technical Documentation for further explanation. 

2.  CFS data for pipelines exclude most shipments of crude oil.  See the
"Shipment Coverage" section of the Technical Documentation for details of CFS
