in great quantities at the south point of Store Koldewey, before they 
escape into the sea. Å few of the south going icebergs continue along 
the shore towards the south, through the water between Hochstetters 
Forland and Shannon. 
The large number of icebergs formed from Storstrømmen in 
reality only take up a little space in Dove Bugt, where the general 
impression is that only here and there does one come across an 
iceberg. From Stormkap, at an altitude of about 40 m I have, with- 
out a telescope, only been able to count about three hundred ice- 
bergs, which also shows their scattered position. 
Ås stated above, it is only possible to reckon with at most one 
month in the year, in which there is so much open water in Dove 
Bugt that the icebergs may go adrift, and as a rule they are not even 
_ able to make use of the short period of liberty granted them by the 
fjord ice, because of their being stranded. 
The immediate impression received from a consideration of the 
difficult conditions under which the icebergs of Storstrømmen must 
work their way, first through the narrow and densely packed sound 
between Edvards Ø and Carl Hegers Ø, and later on through Dove 
Bugt, is that the large icebergs in this part of Greenland must be 
able to attain a very considerable age, before they disintegrate. 
In Medd. om Grønl., ТУ, р. 108, К. ГУ. STEENSTRUP. published 
some experiments on the melting of the glacier ice in sea water, and 
he proved that quite small fragments of calving icebergs only have a 
very small power of resistance in the sea water. A fragment of ice 
of about 11 kg, which was lowered into sea water at a temperature 
of about — 1.3, lost from the very beginning about 1°/o of its own 
weight per hour. 
The absolute melting must be proportionate to the surface of 
the part of the iceberg lowered into the water, and the loss of weight 
in proportion to the weight of the entire iceberg thus becomes 
inversely proportional to the linear measures. The linear measures 
of one of the larger icebergs of Storstrømmen may be estimated at 
about a thousand times the measures of the fragment of ice used 
by STEENSTRUP for the melting experiment, according to which they 
thus ought to reach an age about a thousand times that of the 
fragment of ice used in the STEENSTRUP experiment, i. e. nearly ten 
years. Ås will be shown in the following, it must in reality be sup- 
posed that the icebergs may reach an age many times greater. 
The hydrographic measurings undertaken by TROLLE in Dove 
Bugt at depths which can be taken into consideration here, show a 
temperature considerably lower than + 1.3. In particular I will draw 
attention to the two hydrographical stations LVI from 28/V 1908 and
