vl PREFACE 



ing me free use of unpublished data from the last cruise of the Carnegie. 

 I am also greatly obliged to Mr. W. C. Jacobs for allowing me to use 

 several figures from his as yet unpublished paper on the exchange of heat 

 and water vapor between the oceans and the atmosphere. 



Valuable assistance has been received from Mr. L. Lek, who has 

 carried out a large number of calculations of transport by ocean currents 

 and of net heat received by the oceans in the Northern Hemisphere. 

 Most of the illustrations have been prepared especially for either the 

 larger book or for this one, and credit for them is due Mr. E. C. La Fond. 

 The manuscript has been critically examined by Mr. R. H. Fleming, and 

 parts have been read by Messrs. J. Holmboe, of the University of Cali- 

 fornia at Los Angeles, C.-G. Rossby, of the University of Chicago, and 

 C. L. Utterback, of the University of Washington, all of whom have 

 made helpful suggestions. To all these I extend my sincere thanks. 

 Last, but not least, I wish to acknowledge the help received from my 

 secretary. Miss Ruth Ragan, in correcting the manuscript, in reading 

 proof, and in preparing indices.
