DEEP-SEA DEPOSITS 87 



"Galathea," have been active since our return. From 

 some of them striking confirmation of our own results 

 has been reported (See Chapters 5 and 7) . 



The unique deep-sea electric winch constructed for 

 the "Albatross" was taken over by the Danish expedi- 

 tion and did excellent service during their record trawl- 

 ings and dredgings. We may claim, I think, that the 

 Swedish Deep-Sea Expedition has acted as a catalyst on 

 active interest in deep-sea research in various countries. 



It is not an easy task to give even a highly condensed 

 summary of the main results so far obtained from the 

 material collected by the "Albatross." The rest of this 

 chapter will be primarily devoted to the finds concerning 

 deep-sea deposits and their stratigraphy, and the results 

 of investigations of the long cores raised from great 

 depths in the Atlantic, Pacific, and Indian Oceans. 



Because of the energy and foresight of Kullenberg, 

 who himself raised the cores from the ocean floor and 

 supervised the packing and storing of long cores, the 

 material suffered very little change and could be sam- 

 pled in a most efficient manner. On an average, samples 

 were taken from each ten-centimeter length of the core, 

 leaving half of the cylindrical core intact as an "archive 

 half" for future supplementary and confirmatory meas- 

 urements. 



The chemical analyses of four of the most important 

 components, calcium carbonate, humus-carbon, phos- 

 phorous, and nitrogen, were carried out in the private 

 laboratory of Olof Arrhenius at Kagghamra, Sweden,
