mental conditions in the transition zone crossed., although not specifically 

 in reference to this cruise. Standard Hawaii technique was employed except 

 for a circular tank incubator, (King, Austin and Dot>, 1957). 



7043 , Cruise 43 of the CHARLES H. GI LBERT in which observations vere 

 made in the Marquesas- Tuamotu and Society Archipelagos by H, R. Jitts of the 

 CSIRO on a cooperative project with the Botany Department of the University of 

 Hawaii and the Honolulu Biological Laboratories of the Bureau cf Commercial 

 Fisheries. The scientific crew party chief for thi^ ccuise of the U. S. Fish 

 and Wildlife Service for January through March- 1959, was Robert C. Wllsono 

 Howard 0. Yoshida (1960) has published a resume cf the other types of data 

 gathered, including a description of the cruise. 



A lengthy series of experimental productivity studies was carried out, 



but otherwise standard Hawaii techniques for pigment and carbon-1 productivity 



measurement were employed. The types of special experimental gathering cf 



productivity data are given below. The numerical ymbcls indicating the 



different types of measurements or experiments appearing in technique column 



39 are as follows^ 



* - To the right of column 39 indicates CSIRO standard method 



employed for comparison with the Hawaii standard method. This 

 technique has been described elsewhere (litts, 1957). 



1 - Water samples held in plastic bottles from the time cf sampling 



at 19:00 until incubated at 09:00 the following day. These 

 results can be compared with the standard technique results for 

 * the corresponding 19:00 period;, for the water used was from the 



same sea sample. 



2 - Sample bottles of water collected at 09:00 were incubatel by- 



towing them astern from 11:00 one day until 11:00 the next day, 



6 - In situ incubations by the CSIRO method whereby the samplers were 

 re-suspended in the sea from noon to sunset after inoculation, 

 see Jitts (1957) for the technique.
