Remarks: In the course of the winters 1906 — 07 and 1907 — 08 

 a series of measurements were made of the thickness of the ice, and 

 at the same time samples of surface water were collected for the de- 

 termination of the salinity. 



The measurements of the thickness of the ice were made in the 

 so-called fire-hole (a hole always kept open for access to water in case 

 of fire). 



For measuring, a divided rod with a small projecting angle 

 of iron below was used, the projecting arm being passed under the 

 lower edge of the ice and the distance between this and the surface
