The method used followed the standard Hawaii technique except that the 

 incubator used was of the circular type. It gives light exposures very much 

 comparable to those of the flat type currently in use at the University of 

 Hawaii. A description of the techniques used in this expedition appeared 

 with preliminary calculations of the productivity, phytoplankton pigments and 

 other data (King, Austin & Doty, 1957) . The data appearing under SOOl were 

 also gathered as a part of this "EASTROPIC" enterprise. 



4032 . Cruise 32 of the U. S. Fish and Wildlife Service vessel HUGH M^ 

 SMITH that occurred during February, 1956. The cruise consisted of a 1 day 

 trial of miscellaneous gear and a five day cruise southwest of the island of 

 Oahu. K. D. Waldron of the Honolulu Biological Laboratory was field party 

 chief and Mikihiko Oguri and Maxwell S. Doty of the University of Hawaii 

 Department of Botany were responsible for the productivity work. Waldron 



et al., (Bulletin U. S. Bureau of Commercial Fisheries in mss.) described other 

 aspects of this cruise. Standard Hawaii techniques were employed, some 

 experimental work was done in addition. An "*" to the right of technique 

 column 39 indicated an in situ value. 



4033 . Cruise 33 of the HUGH M. SMITH , April - May 1956 that went from 

 Honolulu to the equatorial region at about 140° West Longitude and back. 

 Productivity work was the responsibility of Mikihiko Oguri. Department of 

 Botany, University of Hawaii^ and James W. McGary^ Fish and Wildlife Service 

 was party chief. 



Standard Hawaii techniques were used, but in addition, various experiments 

 were carried out. Results of these experiments are indicated in technique 

 column 39 by the following symbols t 



* - To the right of column 39 indicates sample probably 

 contaminated with water from the shallower depths, 



1 - Some of the water in the sample bottles was discarded for 

 it was taking an inordinate length of time to filter. The 

 values have been corrected for this by proportion.
