OBJECTS OF THE EXPEDITION 2"] 



waters. Particular attention will be paid to the sorting and studying of the 

 material on board. The following objects and departments will be the 

 subject of special concern: 



a. Benthic fauna at depths beyond 4,000 metres will be explored, both 

 by the use of dredging or trawling gear and by grab. 



b. Fishing for large fish and cephalopods with long line, trap, trawl, etc. 

 will be attempted at all depths beyond 1,000 metres. 



c. Quantitative examinations of the bottom fauna in tropical, subtro- 

 pical, and south temperate waters will be attempted, such examinations 

 to take the form of sectional examinations using quantitative grabs, work- 

 ing from the coast outwards, and down to as great depths as possible. 

 They will concentrate on particular areas off coasts of various types (river 

 estuaries, sandy shores, etc.). Comparative studies will be attempted of 

 continental east and west coasts, etc. 



d. Bathypelagic collections, supplemented by plankton collections in the 

 surface layers, will be made in association with production-biological 

 research. Collections of neritic plankton will be made in certain selected, 

 tropical areas, and near isolated islands. 



e. Every effort will be exerted to elucidate the ecolog)^ of deep-sea 

 organisms by studying the contents of stomachs, possibly also by physiologi- 

 cal examinations, preservation of sexual organs (by special methods), etc. 



f. Hydrographical investigations will be undertaken as required by 

 biological research. 



g. Geomagnetic surveys will be carried out in the abyss. Variation 

 tests will be made to the maximum possible extent. 



h. When in port, collections will be made in the littoral zone, though 

 chiefly in less well-studied regions, off isolated islands, etc. 



i. Only occasional land collections will be made, and these must not 

 interfere with the primary object of the expedition. In south boreal re- 

 gions, however, and off isolated islands, more attention will be paid to 

 land collecting, especially of soil microfauna. 



j. In so far as is possible without detriment to its primary purpose, the 

 expedition will place itself at the disposal of such scientists as may wish, 

 in association with the expedition, to make special studies of a biological, 

 oceanographical, or ethnographical nature. 



In so far as is possible without detriment to its primary purpose, the 

 expedition will endeavour to procure ethnological, historical, and similar 

 material, possibly in exchange for similar Danish material. 



2. In addition to its scientific objects, the expedition will endeavour 

 to spread a knowledge of Danish culture and economic life by means of
