COUNCIL — APRIL 1912 — APPENDIX C — 56 — 



B. When using Ekmans current meter, observations should be taken at a 

 depth of 10 m below surface and 10 m above bottom, and also, if desirable, at an 

 intermediate depth. When using the Libelle current meter, observations should be 

 taken at the usual depths, and also as near to the bottom as possible. 



When using the Libelle meter, measurements should be taken every two 

 hours ; oftener if possible, commencing the series as nearly as possible at complete 

 hours or half hours. 



A complete series of observations as to temperature and salinity to be taken 

 at noon each day, at the usual station-depths; besides these, similar series to be 

 taken as often as possible during a period of 24 hours. 



50 bottom-trailers to be put out at each station at noon on the 1st 

 August. 



Greenwich time to be used. 



With regard to the working up of the current-measurements, it was pointed 

 out that it would be advisable to have this carried out in a uniform manner in 

 the Hydrographical Department of the Bureau, and the redaction of a resolution to 

 this effect (No. 4) was agreed upon. 



The question of an organisation of continued hydrographical observations 

 from fixed stations (lightships and lighthouses) in the Baltic and the Gattegat, 

 was also discussed. The further consideration of this question was placed in the 

 hands of a sub-committee appointed ad hoc; consisting of Messrs: Jacobsen, 

 Schultze and Witting.
