OCEANOGRAPHY AND MARINE BIOLOGY 



AN ANNUAL REVIEW 



Edited by н. barnes 



The very considerable increase in oceanographical and marine biological work 

 calls for a publication summarizing the results. The present series has the 

 following objects — to consider annually basic aspects of marine research return- 

 ing to each in future volumes at appropriate intervals, to deal with subjects of 

 special and topical importance, and to add new ones as they arise. Each article 

 endeavours to cover completely the literature. Physical, chemical, and biological 

 aspects of marine science are dealt with by experts still actively engaged in their 

 own field. 



Volume 1 contains sixteen reviews ; the contents of Volume 2 are announced 

 at the same time and Volume 3 is currently being organized. 



The series will become an essential reference text for research workers and 

 students and should find a place not only in the libraries of marine stations, 

 fisheries institutes, and the like, but also in those of universities and other 

 academic institutions.

GALATHEA'S DEEP SEA EXPEDITION 



1950-1952 



Edited by dr. a. f. brunn, s. greve, 



H. MIELCHE and DR. R. SPARCK 



Translated by Reginald spinks 



The sea covers three-quarters of the earth's surface reaching at the deepest 

 known point some 35,000 feet. Yet so far only four marine-biological world 

 expeditions have set out to study systematically oceanic fauna. The last expedi- 

 tion, that of the Danish Galathea, was made during 1950-52, and proved most 

 successful; partly because of the modern equipment, ship's radar and echo- 

 sounder, all well adapted for deep-sea research. 



The very valuable work and results of this expedition are recorded here by 

 the scientists themselves. After a brief account of the background, origin and 

 objects of the expedition, there are chapters on the technique of deep-sea 

 research — the problems of trawling, echo-sounds, measuring the productivity 

 of the sea and animal density. Then follow chapters of absorbing interest, 

 dealing with he animal life found in the oceans. The Galathea sailed right 

 round the world and the editors have included descriptions of some of the 

 places visited — the Seychelles, islands of the giant palms ; the Nicobars ; Rennell, 

 an out-of-the-way coral island; and Campbell Island, home of elephant seals 

 and albatrosses. 



Deep-sea research is a costly science and expeditions rare. The scientists on 

 the Galathea have made a very fine contribution to the study of the Seven Seas 

 and what they contain. The fascinating illustrations add to the interest and 

 value of this excellent account.
