som paa disse hoje Bredder endnu ikke er gjennemfaret 
af nogen Expedition. Mod Sydvest grunder det i NNW 
for Jan Mayen op til 1300 Favne, et Parti, jeg efter den 
tyske Nordfart kalder det ,Tyske Dyb*, og som har 
sin Fortsættelse dels mod Danmark-Strædet, dels mod Jan 
Mayen-Renden. 
Østenfor Linien Vestspidsbergen—Vesteraalen løfter 
Bunden sig op til nogle faa hundrede Favnes Dyb mod 
Østhavet. Dette er overalt forholdsvis grundt. En Bugt 
paa over 200 Favnes Dyb gaar ind mellem Norge og 
Beeren Hiland, men østenfor den 30. Længdegrad ere 
Dybderne kun mellem 100 og 200 Favne over store Stræk- 
ninger, kun afbrudt af et Par grundere Banker, indtil ind 
under Kysterne. Fra Murmankysten til Novaja Semlja 
ere Dybderne under 100 Favne. Fra Østspidsbergen stræk- 
ker Beeren-Eiland-Banken med udstrakte grunde Strækninger 
sig sydover til lidt søndenfor denne Ø. 
Bundens Heldning fra Kysterne ud mod Dybet er i 
Regelen ikke jevn. Det første Stykke udenfor Kysten

til 500 Favne og i endnu højere Grad Vesteraalseggen,

Mellem disse Steder skyder 200 Favne- Linien udenfor 
Norges Kyst langt tilhavs og Eggen er ikke meget frem- 
trædende. Paa lignende Maade har Shetland, Færøerne, 
Island, Jan Mayen, Grønland, Vestspidsbergen sine Ban- 
ker med mere eller mindre udprægede Egge som Yder- 
grændser. Kartet viser dette bedst. Ved Finmarkens 
Kyst synker Bunden raskt til 100 Favne, men udenfor er 
Havbunden et udstrakt Flak med svage Bølgeformer.

A bay, more than 200 fathoms deep, occurs between 
Norway and Beeren Eiland; but east of the 30th degree 
of longitude the depths average only between 100 and 
200 fathoms, throughout extensive tracts, broken merely 
by one or two comparatively shallow banks, till near the

off the coast of Romsdal, where the bottom throughout 
a short tract sinks from 100 to 500 fathoms, and more 
especially the “ Vesteraalseg,” where the bottom sinks from 
100 to 1500 fathoms, in the Lofoten-Deep. Between 
these points, extends the 200-fathom line off the coast 
of Norway, far out at sea; and the edge is not there very 
prominent. The banks of Shetland, the Færoes, Iceland, 
Jan Mayen, Greenland, West Spitzbergen exhibit a sim- 
ilar formation, with more or less prominent “edges” as 
their outer boundary. Of these, the chart gives the best 
Along the coast of Finmark, the bottom 
sinks rapidly down to 100 fathoms; but farther out the 
sea-bed assumes the character of a wide-extending flat, with 
gentle undulations. 
Above, it has been stated how steep are the average 
slopes of the sea-bed in the Norwegian and North-Greenland 
Seas. From the chart, the best idea will be obtained of 
the actual distribution of these slopes. The steepest decline
