the water. Manœuvred S.W. between the ice-fields. There was quite 

 a quantity of drift-wood. Weather ■ fog. Wind : still. 



"/7. Noon position cal.: 77°08'N., 16°06'W. Steered W. some 

 5 miles. The ice became gradually more and more scattered and at 

 ca. 16° W. the course was set due S. Made soundings and trawled. 

 In the course of night the fog cleared now and the course was set 

 due S. E. The ice-fields still lay scattered about, but became heavier 

 and in part more screwed. Weather: fog. Wind: southerly: strength 2. 



28/7. Noon position cal.: 76° 06' N., 13° 26' W. Steered S. E. 

 through very scattered ice. Lay at anchor in the night to repair 

 leaking boiler tubes. Made hydrographical observations and trawled. 

 Weather: fog. Wind: southerly; strength 3. 



29/.. Noon position obs.:" 75° 40' N., 11°10'W\ Steered due S.E. 

 from 9 a.m. till 5 p.m. Passed by a number of a large ice-fields, 

 which lay in N. — S. direction, from 5 to 10 p. m. Taking soundings 

 all the time. 10 p.m. at IQi/g" W. long, a sounding gave 500 m., no 

 bottom. Almost at the same time the water became practically free 

 of ice, whereas in the previous hours we had manœuvred in the fog 

 from the one ice-lock to the other between the large ice-fields. 

 Weather: fog with clear inteгл•als. Wind: S.W.: strength 4. 



30/,. Noon position cal.: 75° 26' N., 9° .34' W. Steered S. E. through 

 a belt of small, broken hummocks with a few larger floes of ice. This 

 small [ice has been packed together fairly closely by the easterly 

 wind. Animal life very rich. Quantities of seals, little auks, gulls 

 etc. Weather: fog with clear intervals. Wind: easterly; strength 1. 



31/7. Noon position: 74°58'N., 8°05'W. Steered S.E. in water 

 almost free of ice. Marked increasing swell from S. E. 3 p. m. came 

 to the outermost edge of the ice. The ice-floes dense. Sailed 

 up and down the ice-edge, but as there were no openings for a pas- 

 sage through the floes, we chose a place where swell appeared 

 strongest. Here, as was to be expected, the ice belt was quite thin 

 and we quickly broke through. The water was quite greenish from 

 small algae. 



i/g — lä/g. Homeward bound under sail and steam. Made observa- 

 tions on the surface-water on the way. I 



^^Ig. Sailed into Bergen. 



Soundings. 



1. Greenland Sea. 

 a. Apparatus and methods. 



These soundings were made from the Expedition's vessel " Dan- 

 mark" partly in 1906 on the way in towards the coast of North- 

 East Greenland, partly in 1908 on the way home.
