to the influence of the same winds from N and NE the fact,
that the Ymer, on her return from the Yenisei the 1st
September, crossed the whole Kara 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 obstruction from
the ice. 1
In the following table are registered all observations
concerning the temperature, saltness and spec, gravity of the
sea-water at various depths, which were made during the traverse
of the Kara Sea from the 1st to the 20th 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 by the author on water-samples from the collections of
the expedition. On the hydrographic maps [plates 24, 25, 26]
the results of the investigation is graphically represented by
means 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 study 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 Kara 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. wTeights observed in
the water at the surface are of far less importance than the
observations from the deeper layers.
1 . . . Nous gouvernâmes alors, comme l’année passée, au Cap
Mid-dendorff. La mer était d’abord entièrement exempte de glace; ce ne fut
qu’en arrivant tout près de la côte orientale de la Nouvelle-Zemble, par
75° 80’ Lat. N. que nous aperçûmes un banc de glace rongée, qui s’étendait
le long de la côte vers le Matotchkin. ... Si en quittant le port Dickson,
nous étions allés directement au Matotchkin en doublant l’île Blanche,
nous n’aurions certainement pas rencontré un seul glaçon. [Expéditions
