equipment, and a long list of other essentials. For experimental work at sea, fully 

 equipped floating laboratories are needed to study live specimens at the source. And 

 perhaps most important of all is the need for an increasing number of well-trained 

 marine biologists and technicians. 



The Sears Foundation extends its gratitude to Henry Bigelow and Giles Mead for 

 their various contributions in bringing these three volumes to fruition, particularly for 

 harvesting the manuscripts. To those authors who have given their generous cooper- 

 ation in achieving uniformity in the presentation of the material and in supplying ad- 

 ditional information, I extend special thanks. Many of the authors have acknowledged 

 the help and cooperation of individuals and institutions ; to them, and particularly to 

 the many who have been omitted, I add the gratitude of the Sears Foundation. It is also 

 a special privilege to note the continued interest and confidence of Henry Sears, who 

 has generously aided in the financing of these volumes, and to acknowledge financial 

 support of various author investigations by the National Science Foundation. In the past 

 two or three years, the Editorial Board has been expanded by the addition of Daniel 

 Cohen, Giles Mead, and Daniel Merriman to its roster; to them and to the older mem- 

 bers of the Editorial Board, the Sears Foundation is grateful for many and varied 

 services. 



Finally, it is with no small regret that I note the discontinuance of Albert Parr's 

 active participation in the functions of the Sears Foundation and in the publication of 

 these Memoirs and the Journal of Marine Research., both of which were conceived and 

 brought into being as a result of his sincere and deep interest in all things marine and of 

 his keen perception of the need for vehicles to distribute the thoughts and scientific 

 observations of an expanding oceanographic community. The results seen in the publi- 

 cations themselves speak for his contribution far more significantly than mere words
