84 EIGHTH PACIFIC SCIENCE CONGRESS 



Pilgrim has begun a revision of New Zealand Nudibranchia, and Pro- 

 fessor E. Percival is working out the life history of Tegulorhynchia ni- 

 gricans as part of his general interest in brachiopoda in New Zealand 

 tidal waters. 



NEW ZEALAND GEOLOGICAL SURVEY. 



Mr. N. de B. Hornibrook continues study of marine Ostracoda and 

 Foraminifera, particularly Globigerinidae, which may be useful paleo- 

 temperature indicators. Mr. P. Vella has completed a survey of the 

 Foraminifera of Cook Straits. 



SUMMARY OF OCEANOGRAPHIC WORK CONDUCTED BY 



THE PACIFIC OCEANIC FISHERY INVESTIGATIONS 



SINCE 1949 



Objectives: 



To survey the distribution of physical, chemical and biological pro- 

 perties of the waters of the central equatorial Pacific and to combine 

 the resultant oceanographic data with those from the experimental 

 fishing operations in an effort to better understand the particular eco- 

 logical situations in which the fish are present or absent. 



Facilities: 



The major portion of the oceanographic survey program has been 

 carried out aboard the Hugh M. Smith, a former Navy YP of the 600 

 class. The Smith is 128 feet long with a beam of 29 feet; is powered 

 with a 560 H.P. Union Diesel and has a cruising range of 8,500 miles. 

 The present oceanographic equipment includes two winches for raising 

 and lowering Nansen bottles and for towing plankton nets; a bathy- 

 thermograph installation; and automatic surface temperature recorder, 

 and a GEK (Geomagnetic Electrokinetograph) for recording velocities 

 of surface currents. 



An oceanographic and biological laboratory is located on the main 

 deck where chemical analysis are made and where biological specimens 

 studied and preserved. 



The John R. Manning, west coast purse seiner, and the Charles 

 H. Gilbert, a combination tuna boat and longline vessel, are both 

 equipped with recording thermographs and with bathytheraiograph in- 

 stallations. Plans for a biological-oceanographic laboratory aboard the 

 Gilbert are presently nearing completion. 



Laboratory and office space are available in the POFI building 

 located on the campus of the University of Hawaii. A calibration tank 

 for reversing thermometers and limited shop facilities are also provided.
