The estimated numbers of instruments and instrument systems contain- 
ed in the descriptions have been based upon the following considerations: 
(1) That, from the TENOC Report, NASCO Report, and personal communications, 
the following oceanographic ships exist and/or are proposed for future 
construction, and (2) that some of the proposed ships will replace some 
of the older, existing ships.
