Inorganic phosphates Two phosphate sections were drawn 

 and appear as figures 9 and 31 „ In figure 9, there are large variations 

 in the concentration of inorganic phosphate below the thermocline. 

 "Pools" of high or low concentration appear almost at alternate sta- 

 tions in the deeper water and often are found at stations where the 

 concentrations in the surface layer are correspondingly high or low„ 

 This suggests that these variations are not in the ocean, but arise 

 fictitiously in the determinations 



Surface water with a relatively high inorganic phosphate 

 concentration appears near the Equator on both cross sections,, This 

 prevalent feature of the central Pacific is associated with the equa- 

 torial upwellingo 



Oxygen; Oxygen sections appear as figures 10, 19 s 25, 

 and 32„

I wish to express my appreciation to Mary Lynne Godfrey, 

 Richard V. Mead, and to those persons who worked with them in pro- 

 cessing the physical data and plotting the sections,, Winifred Tseu 

 carried out the chlorinity titrations and processed the chemical data, 

 Tamotsu Nakata drafted the figures,, Thomas S a Austin made helpful 

 suggestions and assisted generously in the later stages of the work 



The scientific field party during cruise 5 was: Joseph 

 E King (field party chief), Townsend Cromwell, Kenji Ego, Herbert 

 Mann, Vernon Brock (Territorial Division of Fish and Game) and 

 William Gosline (University of Hawaii),, During cruise 8 the field 

 party was: Joseph E s King (field party chief), Herbert Mann, Richard 

 Mead, Stanley Peterson, Isaac Ikehara and Walter Kawano 



There were many other persons who assisted in this work 

 at sea and ashore and I gratefully acknowledge cheir contributions .
