COUNCIL ^ SEPT. 1910 - APPENDIX A — 24 — 



Resolution No. 4. 



The international Council having discussed the proposals of the Danish Com- 

 mission to anchor a ship for 2 months in the North Sea for hydrographical and 

 other observations, agrees that the time has now come to investigate in greater detail 

 the fluctuations of the different hydrographical and biological elements in the North Sea. 



To this end, having regard also to the questions put forvrard by the Dutch 

 and British Governments (comp. Proc.-Verb. VI 24, VII 30), it is resolved that ob- 

 servations of temperature, salinity and currents, and of plankton and other biological 

 conditions be taken at 7 selected positions at several depths from anchored ships at 

 short intervals during a period of 14 days as early as possible in June 1911. At 

 the same time similar observations at lightships should be carried out. 



These observations of temperature, salinity and currents are to be published 

 together in the Hydrographical Bulletin; and the Assistant for Hydrography is in- 

 structed to prepare a digest correlating the results obtained. 



Note: The following suitable positions for these observations , 'are recommended: 



for the Swedish ship: nearly at Station Dil (57° 17' N— 7° 47' E; 54 m). 



- - German — : Station D6 (57° 55' N— 4° 45' E; 103 m). 



- - Norwegian — : between 58° and 59° N, at 2° E Long. 



- - Scotch — : — 57° and 58° N, 0° and 1° M^ Long. 



- - English — : near at 55V4° N— 0,3° W. 



- - Dutch — : between 54° and 55° N, 4° and 5° E Long. 



- - Danish — : — 56° and 57° N, 5° and 6° E Long. 



As suitable lightships the following are in the first place to be pointed out: 

 Horns Reef, Smith's Knoll, Varne, North Hinder. 



Fisheries and In accordance with the resolution passed at the last Meeting of the Council 



Statistical (-Vol. XII, p. 34, U) the Bureau lay the following proposals before the Council, viz : 



(a) That the Reporters for the problems 2, 4, 5 and 7 on p. 56 of Procès-Verbaux 

 Vol. XI be continued; and those on problems 1, 3 and 6 for the present dis- 

 continued. 



(b) That new Reporterships should be instituted in the current year to deal with 

 the following problems, viz: — 



(1) The present state of our knowledge regarding the races of the chief food 

 fishes. 



(2) The migrations &c. of certain "Clupeoids" other than the Herring, especially 

 the Anchovy and the Sardine. 



(3) The biology and migrations of the Mackerel. 



(4) The salmon fisheries of the Baltic with special reference to the preparation af a detailed
