Tversnit X gaar fra Langanes, Islands Nordostpynt, 
tvers over det norske Hav til Foldenfjorden. Den højeste 
Varmegrad i Overfladen, over 8°, findes over de norske 
Kystbanker, den laveste, 2°, østenfor Island. Paa 
norske Side bliver det koldere under Land (6.06), paa Is-

Tversnit XIII (Pl. XI; den vestlige Del af Snittet 1

Renden og Norskedybet til den norske Kyst søndenfor 
Vestfjorden ved Trænan. Den højeste Temperatur, mellem 
7 og 8°, findes over og udenfor de norske Kystbanker. 
Det er koldere under Land, 6°. Varmegradsisothermerne ligge 
i dette Snit, som i de forrige, temmelig tæt og have i det

sig, navnlig under 3°, raskere opad. Isothermen for 0° lig- 
ger 1 den østlige Del af det norske Hav paa omkring 400 
Favne, eller oftest noget dybere. I Syd for Jan Mayen 
bøjer den, ligesom de øvrige Isothermer, raskere op mod 
Overfladen i Jan Mayen-Renden, og skraaner langsomt 
opad paa en længere Strækning, indtil den i Grønlands- 
havet nordenfor Island naar Overfladen. - Største Delen af 
Snittet indtages saaledes af iskoldt Vand, med Kuldegrader.

Throughout the depression formed by the Fro Sea within 
the Fro Islands, the deep part exhibits a temperature of 
7°, whereas near land the water is colder. 
Section X extends from Langanes, the north-eastern 
extremity of Iceland, straight across the Norwegian Sea, 
to the Foldenfjord. The highest temperature at the surface, 
above 8°, occurs over the Norway coastal banks, the low- 
est, 2°, east of Iceland. On the Norwegian side, the 
water gets colder towards land (6.°6), on the Iceland side 
warmer. Over the whole section, the isotherms for the 
higher temperatures crowd together in the upper strata. 
The temperature 0° lies deepest (400 fathoms) in the 
middle of the section, and but little higher throughout its 
eastern part. Towards Iceland, on the other hand, the 
isotherm for 09 rises to 200 fathoms, at Station No. 51, 
and there reaches rapidly a depth of less than 100 fathoms 
(See Section V). Near the Iceland Bank it sinks somewhat 
deeper down, to 200 fathoms. The isotherm for — 1° lies 
deep (1200 fathoms) in the middle of the section, rising up 
on either side to 400 fathoms, A similar course charac- 
terises the isotherm for —1°.1. The lowest temperature 
in the section, — 1°.2 to — 1°.3, keeps principally on the 
eastern slope, where it rises from 1700 up’ to 600 fathoms, 
but is also met with on the western. In the depression 
off Iceland, the Danish explorers observed — 14.2.

Section XIII (Pl. XI; the most westerly part of the 
section in the middlemost row to the left) extends from 
Greenland across the Jan-Mayen Channel and the Norway 
Deep as far as the Norwegian coast, south of the Vestfjord, 
at Trænan. The highest temperature, between 7° and 89, 
occurs above and off the Norway coastal banks. The water 
is colder inshore, 6°. The isotherms for temperatures above 
09 lie in this section, as in the others preceding it, rather
