Snow temperature +0.3°. The snow wet. Below the 

 snow a crust of ice and then water on the ice. 



A hole cut at a spot which looks to be solid ice, 

 provesthis tobe compressed snow. Below the snow 

 there is water on the ice with a temperature of +0.1° 

 and salinity of 9 6 %„ at a depth of 50 cm. 



The thickness of ice measured in '.i natural holes 

 and 1 hole cut in the ice. 



Hole cut through porous and rotten ice. Bubbles of air 

 rising up in pools of water. When the current is 

 strong, particles of ice are carried away from the 

 under side of the ice so that the water becomes turbid. 

 When the current is slack, the water is clear. 



Ice porous and soft. 



A quantity of melting ice and snow has run off the 

 ice, which has risen. 



Water and "mush" on the ice 24 cm. 



Ice becomes more and more rotten. Many vertical 



channels, which gradually increase in extent. 

 Air-bubbles rising in the thawing openings. 



Water and "mush" on the ice 10 cm. deep. 



Water and "mush" on the ice 12 cm. deep. 



In a pool on the ice a spring of water observed coming 

 up from a small hole in the ice and caused by air- 

 bubbles rising in such large numbers and so rapidly, 

 that the water was carried up with them and rose 

 5 — ti cm. above the surface of the water in the pool.
