42 THE OCEAN FLOOR 



cruises concernintr the seothermal gradient existing in 

 deep-sea sediments." This subject was also on the pro- 

 gram of the "Albatross" cruise but for technical reasons 

 only three trustworthy measurements could be ob- 

 tained. Scripps Institution enjoys the unique position of 

 being on the verge of the most interesting part of the 

 deep ocean floor, that of the eastern and central Pacific. 

 I am sure its future work will be of the very first impor- 

 tance to the new science of submarine geology, in which 

 an eminent representative of Scripps, Francis Shepard, 

 has for years been active. Another member of that staff 

 and one of the world's foremost authorities on the 

 Foraminifera in sea sediments, Fred Phleger, accom- 

 panied the "Albatross" from Martinique to Cristobal, 

 making investigations on the planktonic forams and 

 sampling one of our longest cores, taken from the 

 Caribbean Sea. The results of this analysis Phleger 

 published while the expedition was still under way.^^ 

 Together with Frances Parker and Jean Peirson, he 

 has generously shouldered the heavy burden of studying 

 the Foraminifera in our cores from the North Atlantic 

 Ocean. Also, through his visit on board the "Albatross" 

 and through a later visit to Sweden he has done much to 

 clear up certain misunderstandings regarding the extent 

 and quality of the work we were carrying out. The

 cation in the new journal Deep-Sea Research (Pergamon 

 Press, London).
