Notes on the sea-ice along the east coast of Greenland. 913 
Shoal, has more space to spread in than in years when large masses 
of ice can drift down. The obvious conclusion of this is that the ice- 
belt will be more open south of the shoal with the ice adhering to it 
in summers following upon a cold and particularly calm winter, than 
in summers when the contrary has been the case. 
This also corresponds with Amprup’s theory regarding the for- 
mation of the North Bay between 74°—76° N. Lat., and when looking 
over the material at hand regarding this question, i. e. a list of thirty- 
two vessels, which we know to have penetrated the ice-belt, it will be 
seen that by far the greater number have penetrated the ice-belt to the 
coast of Greenland on 74°—75° N. Lat. There are of course many more 
ships, which have reached the coast of Greenland, but these are not on 
record.

This list will probably undergo some changes in years to come, as 
more ships are likely to go through the ice further to the north, where 
it is known that an unbroken mass of ice exists on 76°—77° N. Lat., 
all the more as there is reason to suppose that better ice-conditions 
are to be found close under this body of ice, as the loose ice will drift 
away from it.
