Reports of the Committee appointed to investigate the values 
of Cl, SO; and o, in a series of water-samples 
This Committee was appointed by the Hydrographical Section on July 18th, 
1905 and consists of the following members: Kriimmen, Nansen, PETTERSSON and 
KNUDSEN. 1 
It was decided to obtain water-samples as far as possible from the following 
regions: 
Sample No. 1: Gulf of Bothnia, surface layer, ca. 3—4°/oo salinity ; 
9: Gulf of Bothnia, bottom layer, ca. 60/00 salinity; 
3a: Skager Rak (Station SS), ca. 60 m. deep; 
3b: Skager Rak (Station SS), bottom-waler, ca. 650 m.; 
4: Norwegian Sea, east side, bottom-layer of less than — 1° C; 
5: Norwegian Sea, west side, bottom-layer of less than — 1° C; 
6: Gulf Stream water from ca. 200 m., S > 35:2 %/oo; 
7: East Greenland Stream in ca. 50 m., S > 34 %o; 
8: East Greenland Stream, upper layers, melted ice water, S < 33 %o; 
9: Atlantic Ocean, deep water from the northeastern part (from about 
the region of Rockall); 
10: Atlantic Ocean, surface water from the region of the Azores, 
S > 36/00; 
11: Bottom water from the same region, t< 3° C; 
12: Mediterranean, deep layers, 1000—2000 m. 
The Central Laboratory undertook to procure the necessary bottles, filters 
etc. and to give instructions for the collection and preservation. According to 
information received from the Central Laboratory the preparation of the bottles 
etc. and the elaboration of the instructions are now completed. Further, the 
Central Laboratory will distribute the samples to the various laboratories for 
investigation. 
The investigations will be made in the Central Laboratory as also in the 
Hydrographical Laboratories of Kiel and Helsingfors. 
The collection of the samples is to begin in May 1906. Prof. Homsn has 
promised to take the samples No. 1 and 2; Prof. Perrersson the samples No. 3a 
and 3b. The two last will be taken in double quantity in order to send the 
material also to the Oceanographical Museum in Monaco and to Professor THoULET
