NS/IOC/INF -17 (Continued ) 



(k) Biology. Data jn quantity and composition of 

 plankton standard layers, if feasible. 



Other observations 



References should be given for inclusion in VVDC Indexes, 

 of any types of data obtained, e.g., submarine geology, 

 submarine geophysics, special echo soundings and marine 

 biological observations. 



General 



(a) Results slould be presented chronologically for 

 each expedj r.ion beginning with its first day of 

 work . 



(b) Each table heading is to contain the date, time, 

 and the name of the observing ship (or station) and 

 be accompanied by a chart showing the positions of 

 ship stations. An indication is to be given of how 

 positions have been fixed, e,g,, dead reckoning, 

 observation, bearing, etc„ 



(c) The time in use is to be stated, eog., GMT or time 

 zone; and in the case of a serial station the time 

 is that of dropping the messenger for the first cast 



(d) Data should be presented in final processed form 

 after all instrumental corrections have been made^, 

 but, in the cas.^ of serial stations, interpolation 

 to standard depths is to be omitted if this will 

 delay transmission. 



Time Schedules and Transmission 



Cruise data are to be forwarded as expeditiously as 

 possible ands,in any case, not later than 6 months after com- 

 pletion of the cruise. In the case of Antarctic expeditions 

 and similar long cruises during which analysis may be con- 

 ducted on board, three months is the desirable interval after 

 the end of the voyacje. All other data should be forwarded 

 within one year after collection. 



One copy of the data is to be sent to both WDCs whenever 

 feasible. Alternatively, data should be sent in duplicate to 

 one of the l/VDCs. The method used is to be made clear on the 

 Transmittal Note.
