A report such as this is necessarily a cooperative enterprise. Information is taken 

 not only from various publications but a great deal of it, perhaps most of it, has been 

 contributed by persons sympathetic with the purpose of the work. On the trip around the 

 world and on other visits to oceanographic institutions, everywhere the attitude was that 

 of sympathetic helpfulness. The governmental officials, the chiefs and the other members 

 of the staffs of oceanographic institutions, and the members of the faculties of the various 

 universities did everything possible to supply desired information. An imperfect list 

 of those from whom assistance was received on the journey around the world contains the 

 names of fully one hundred persons. These are thanked without listing individual names 

 but the names of those who have contributed to the report, either sections or manuscript 

 data, will be recorded. 



Prof. Harald U. Sverdrup, formerly of the Michelsen Institute in Bergen, Norway, 

 and now the Director of the Scripps Institution of Oceanography at La JoUa, California, 

 and Prof. B. Helland-Hansen, Director of the Geophysical Institute in Bergen, Norway, 

 have prepared the section of the report entitled "Oceanographic Data, Vertical Sections 

 of Temperature and Salinity for the Norwegian Sea, the Polar Sea, and Adjacent Areas." 

 Much help was received from Prof. A. Defant, Director, and Prof. Georg Wlist, both of 

 the Institut flir Meereskunde, Berlin, Germany. Professor Defant gave permission to 

 use as base charts the charts published by him in his paper entitled "Systematische 

 Erforschung des Weltmeeres," and he also gave permission to use the text and charts to 

 illustrate the section of this report by Professor Wiist on "Horizontal Distribution of 

 Temperature, Salinity, and Density at Standard Depths in the Atlantic Ocean." Pro- 

 fessor Wiist consented to the use of this material and to the translation of the pages of 

 text that accompany the four charts. Messrs. C. O. Iselin and A. E. Parr compiled on a 

 chart the oceanographic stations occupied in the Caribbean Sea and the Gulf of Mexico 

 by the Mabel Taylor and Atlantis. Manuscript information was supplied by Dr. 

 Stanley Kemp and Dr. N. A. Mackintosh on the stations occupied by Discovery II and 

 Wm. Scoresby. Sir Douglas Mawson supplied information on the stations occupied by 

 the Discovery I. Messrs. Hakon Mosby and J. K. Eggvin of the Geophysical Insti- 

 tute, Bergen, Norway, contributed a list of the stations occupied around Antarctica by the 

 Norwegian ship Norwegia. Mrs. Johannes Schmidt and Mr. Helge Thomsen gave in- 

 formation on the stations occupied by the Dana during its circumnavigation of the globe 

 in 1928-29. Dr. T. G. Thompson supplied lists of stations occupied in the north Pacific 

 by the Catalyst. Many manuscript records were received from the United States 

 Hydrographic Office and the Scripps Institution of Oceanography. Colonel R. B. 

 Seymour Sewell supplied information on the stations occupied by the Mabahiss in the 

 Indian Ocean and Dr. C. Crossland prepared a long manuscript list of stations occupied 

 by the same vessel in the Red Sea.
