MEETING — MAY 1918 — 12 — 



Further discussion of this question was then postponed to next meeting. 



Professor Pettersson then drew attention to point 4 of the agenda. 



The Dutch delegates van Everdingen and Redeke reported on a series of 

 Dutch lightships laid out for the duration of the war in a channel in the North 

 Sea which is free from mines (longitude of Utsire). From these lightships regular 

 hydrographical observations were being carried out and these measurements which 

 (as far as known) were the only ones at present replacing the hydrographical work 

 of the North Sea, should be regarded as of high scientific value. The above named 

 delegates further drew attention to the fact that the placing of a Swedish lightship 

 on the said longitude at the entrance of the Skagerack would be of great benefit 

 to hydrographical research and that a resolution in this direction passed to the 

 meeting might further the project of establishing such a station. 



Messrs. van Everdingen and Nordquist were deputed to draw up such a 

 resolution. 



The sitting closed at 1 p. m. 



Second Sitting. 



Friday 24th May 1918; 10.30 a.m. 



Chairman: President Professor Pettersson. 



Present: the same as al the first general meeting in the forenoon of the day before. 



Secretary : Dr. Gehrke. 



Dr. A. C. Johansen and Dr. Redeke gave a report on the results of the plaice 

 investigations carried out in continuation of previous work on the plaice of the 

 North Sea in the years 1916 and 1916 — 17, by Denmark and Holland respectively. 

 As the results of these investigations up till now were not yet sufficient to permit 

 of any decision as to how much the stock of plaice had altered on the Danish and 

 Dutch North Sea coasts since the outbreak of the war, it was recommended for the 

 present to continue these investigations, taking into consideration the relation 

 between size and age. 



Commander Drechsel read the draft of a letter to the delegates of the Inter- 

 national Council, dealing with the necessity of resuming, immediately after the 

 war, international scientific investigations in the North Sea and adjacent waters,
