GEOMAGNETIC INVESTIGATIONS 



245 



cally possible to measure the magnetic force of the Earth sufficiently accu- 

 rately down to at least 3,000 — 4,000 metres, and probably deeper, we 

 had achieved the first geomagnetic objective of the expedition, in spite 

 of many difficulties and the race against time. We now had the experience 

 and the technical basis for attempting the second objective, which was 

 the systematic three-dimensional surveying of terrestrial magnetism in the 

 sea. 



As stated earlier, the expedition had to be cut short owing to rapidly 

 mounting costs. We were thus prevented from following up our initial suc- 

 cess on this occasion. However, on the basis of the experiments described 

 and the experience thereby gained it is our hope that before long a new 

 deep-sea expedition, either from Scandinavia or from some other country, 

 will continue the work from the point at which we had to leave off.
