II ADMINISTRATION-REPORT 1918—1920 



A paper on the influence of cold winters upon the salt bottom-water of 

 the Kattegat is under preparation (Gehrke). An abstract was laid before the 

 meeting in London 1920. 



Attention was paid to the distribution of standard water and the testing and 

 distribution of instruments as in previous years. Experiments on a new method 

 for the determination of light-absorption in sea-water were carried out, and for 

 the consideration of the Bureau a Memorandum on the Hydrographical Depart- 

 ment of the Bureau and the Laboratoire Hydrographique was prepared. 



Plankton Department. 



1. The head of the Department has continued the elaboration of the mate- 

 rial for the concluding "General Part" of the Résumé planktonique. 



The extracts of the different special reports are now finished and their 

 arrangement into general groups is nearly fulfilled, but the final writing of the 

 manuscript is not yet ready. At present an Introduction is ready for print, and 

 the general Alphabetical Index to the three already published special parts has 

 been arranged. It is expected that the whole manuscript will be finished in 

 course of the present year. 



2. The Department has finished the printing of the paper by H. H. Gran 

 and Thorbjorn Gaarder: "Über den Einfluss der atmosphärischen Veränderungen 

 Nordeuropas auf die hydrographischen Verhältnisse des Kristianiafjords bei Drö- 

 bak im März 1916", which appeared in August 1918 as "Publication de Circon- 

 stance" No. 71. 



Biological Department. 



As mentioned in the report of work carried out by the Biological Depart- 

 ment for the years 1916 — 18, the statistics for the year 1913 were sent to Professor 

 D'Arcy Thompson for perusal. The statistics were returned to the Department 

 in the spring 1919 with Professor D'Arcy Thompson's "Introduction" and have 

 been published and distributed. It is expected that the statistics for the year 1914 

 will be edited before the end of the present year ; it has taken a very long time 

 to collect the material for these statistics. The work on the statistics for th,e year 



1915 has been started and is nearly finished, only waiting for some material. For 



1916 several of the participating countries have not yet the material worked 

 out. For certain countries, like Russia and Belgium, we have received no stati- 

 stics since 1912. 



For 1918 — 19 the usual contributions have been paid by Denmark, Great Contributions 

 Britain, the Netherlands, Norway and Sweden. Statement of 



From the Statement of Accounts for the financial year 1918 — 19 (see below) 

 it will be seen that the balance at the end of the year was Kr. 61137.66.
