entrance with a depth of less than 100 m., whereas in Store Belt the 

 depth on the bar is over 300 m. and the deep water extends south 

 round the southern Koldewey Island, continuing as a submarine fjord, 

 which transects the Continental Bank at ca. 75'/4° N. lat. 



From Dove Bugt the Hellefjord and Mørkefjord cut right into 

 the inland ice. 



In the fjords and sounds more to the south (Hellefjord and sounds 

 between Edwards Isl. and Carl Hegers Isl.) no soundings were taken. 

 They seem to be deep in the westernmost part as here there were 

 floating icebergs from Brede Glacier and L. Bistrups Glacier ; the height 

 of these above the sea was 30 — 40 m. and their depth must con- 

 sequently have been ca. 300 m. — At the mouth of the fjords (to- 

 wards east) most of the icebergs were grounded. 



Deep water, which permitted passage of the icebergs, was found 

 through A. Stillings Sound south of Teufelkap and was here prob- 

 ably in connection with the already mentioned deep water in Store 

 Belt. 



Temperature and salinity observations. 



1. Apparatus. 



2 Pettersson-Nansen water-bottles Nos. 86 and 89. 



2 Ekman water-bottles. 



4 thermometers for the Pettersson-Nansen water-bottles. 2 pro- 

 tected (23505, 23507), 2 unprotected (25207, 25208). 



2 Richter reversible thermometers, Nos. 769 and 803. 



2 cases of areometers. 



2 meter-wheels (1 large and 1 small). 



500 half-litre bottles for water-samples (in 10 boxes). 



3 burettes. 



3 pipettes (15m., Knudsen). 

 25 tubes normal water 



All the instruments were delivered and controlled by the Central 

 Laboratory of Christiania. 



The Pettersson-Nansen water-bottles were of the ordinary, well- 

 known construction with thermometer attached. 



I may assume, that the construction of these is so well-known, 

 that a detailed description here is superfluous. 



The water-bottles were without propeller, so that we always had 

 to use a sinker, which meant a considerable loss of time at the 

 greater depths, but on the other hand ensured a greater certainty in 

 the working.
