Appendix G 



Proposal of the Danish Commission 



to have continuous observations made from an anchored vessel 

 in the North Sea during two months of the summer. 



As it will be of the greatest importance for all present and future investi- 

 gations in the North Sea to have some knowledge of the hydrographie and biolo- 

 gical changes which take place in the deeper layers of water during a short period 

 of time, it is proposed to have a continuous series of investigations made from an 

 anchored ship. With regard to the hydrographie investigations, such an under- 

 taking will probably assume so much importance that it must be carried out 

 sooner or later; only in this way will it be possible to get detailed information 

 about the currents in the deeper layers for a long enough time to display the 

 effects of the different meteorological conditions. 



By such an undertaking it will be possible, in a more complete and more 

 rational way than hitherto, to procure really connected observations of the hydro- 

 graphic and biological conditions, and through the continuity of these observations 

 obtain material which may be expected to be specially well suited to elucidate the 

 question of the connection between the hydrographie, planktological and biological 

 changes. 



Out of regard for these considerations, it is proposed to extend the investi- 

 gations over a period of two months, at a spot which may be indicated by the
