HYDROGRAPHY. 



The ice-water of the Polar Current owes, as we know, its characteristical features to water frozen 

 to ice and to ice converted into water. It is a well known fact that the sea-ice often is driven in a 

 southerly direction along the east-coast of Iceland, and by this circumstance proves in what direction 

 the Polar Current is flowing in these regions of the sea. According to the annual publication 

 from the Meteorological Institute, «Meteorologisk Aarbog for 1896, 3 volume*, it can 

 be seen in the charts, representing the conditions of the ice in the seas east of Greenland and in the 

 Davis Strait, that in May 1896, the ice in the latitude of Cape Langanas has driven as far to the 

 eastward as 7° longitude west of Greenwich, that is to say almost to the very place, where, according 

 to the observations made by the Ingolf expedition, we may expect to find the boundary between Polar- 

 water and North -Ocean-water. Part of the ice is melted in this tract of the sea, but the rest of it 

 has driven away and left the ice-water behind, in which a great deal of the observations of the Ingolf 

 expedition have been made. 



The salinity curves for the stations in the ice-water have, in so far as this layer of water is 

 concerned, been drawn over entirely insufficient data, as it can be seen from the determinations that
