352 FETTEBSSOX, SIBERIAN SEA. 



to the influence of the same wiiids from N and NE tlie fact, 

 that the Ymer, on her return from the Yenisei the 1*' Sep- 

 tember, crossed the whole Kära Sea from Port Dickson to the 

 Matotchkin Shar and even made a long detour to the North 

 up to 75° 30' Lat. without meeting with any obstriiction from 

 the ice. ^ 



In the following table are registered all observations con- 

 cerning the temperature, saltness and spec. gravity of the sea- 

 water at various depths, which were made during the traverse 

 of the Kära Sea from the V to the 20*^ of August, 1878. Of 

 the chlorine titrations one part is made on board the Vega 

 by various members of the expedition. The numbers thus 

 obtained are signed »V». Another part (denoted by »P») is 

 made b}^ the author on water-samples from the collections of 

 the expedition. On the hydrographic raaps [plates 24, 25, 26] 

 the results of the investigation is graphically represented by 

 raeans of the sections I — XI. These sections, which show the 

 depth of the sea and the conformation of its deeper water- 

 strata, correspond exactly to the track of the Vega represented 

 by the black line on the map. Neither the tables nor the 

 maps need any further explanation. Every date, which is 

 necessary in order to initiate the reader into the hydrographic 

 state of the sea, can easily be found either in the tables I, II, 

 III & IV or by a comparison of the map and the sections. 

 My sole object has been to arrange the matter in a manner 

 adapted to stud}'' and inspection. The graphic illustrations 

 as well as the description on the foregoing pages apply strictly 

 to the actual state of things at the time of observation i. e. 

 August & September, 1878. I am well aware, that the conditions 

 of all parts of the Siberian ocean and the Kära Sea most of all 

 are liable to great variations from one year to another. This 

 is especially the case with the conformation of the upper 

 strata, therefore the temperatures and sp. weights observed in 

 the water at the surface are of far less importance than the 

 observations from the deeper layers. 



"... Nous gouvernämes alors, comme Tannée passée, au Cap Mid- 

 dendorff. La mer était d'abord entiérement exempte de glace; ce ne fut 

 qu'en arrivant tout prés de la cöte orientale de la Nouvelle-Zemble, par 

 7.5° 30' Lat. N. que nous aperQiimes un banc de glace rongée, qui s'étendait 

 le long de la cöte vers le Matotchkin. ... Si en quittant le port Dickson, 

 nous étions allés directement au Matotchkin en doublant Tile Blanche, 

 nous n'aurions certainement pas rencontré un seul gla^on. [Expeditions
