som nordenfor findes betydelig større Dyb paa indtil over 
2000 Favne (3658 Meter). Østliavet, det vil sige Havet 
østenfor en Linie fra Spitsbergen til det nordlige Norge, 
er overalt meget grundt. da Dybden der paa faa Steder 
overskrider 200 Favne (366 Meter). 
De talrige udførte Temperaturobservationer vise. at 
Våndet i den af Expeditionen undersogte Del af Østliavet 
med 1 ndtagelse af den østligste og nordligste Strækning 
bolder Varmegrader ligefra Overfladen til Bunden, saaledes 
som dette ogsaa er Tilfælde med Våndet paa de norske 
Banker, som paa enkelte Steder strækker sig ml til en 
ikke ubetydelig Afstand fra Kysten. Helt anderledes er 
Forholdet i det vestenfor liggende dybere Hav, som med 
Hensyn paa Temperaturforholdene naturlig kan inddeles i 
2 Hovedstrøg, den i den østlige Del nordover gaaende saa- 
kaldte Golfstrøm og den i den vestlige Del sydover gaaende 
østgrønlandske Polarstrøm. Grændsen mel lem disse gaar 
nordenom Island op til Jan Mayen, bøier i en Bue sønden- 
om og østenom denne og overskrider paa omkring 3° vestlig 
Længde med nordostlig Betning den 71de Breddegrad. 
Herfra gam* den mod Øst til lienimod 7 "østlig Længde og 
fortsætter derfra i nordlig og lidt vestlig Betning til nor- 
denom den 80de Breddegrad. 
I den. østenfor denne Grændse beliggende Del af 
Havet besidder Overfladevandet en forholdsvis hoi Tempe- 
ratur. der endog overskrider Luftens midt om Sommeren, 
hvorhos ogsaa Våndet i de nærmest under Overfladen be- 
liggende Lag holder Varmegrader, saaledes at 0" først fore- 
findes i et Dyb af omkring 500 Favne (914 Meter), hvor- 
fra Temperaturen jevnt og langsomt synker til omkring 
— 1.°3 ved Havbunden. 
I den østgrønlandske Koldvandsstrom er derimod Tem- 
peraturen i selve Overfladen meget lav men om Sommeren 
i isfri t Vand dog overalt over 0 U , medens den allerede fra 
faa Favnes Dyb og nedover lige til Bunden holder sig 
under 0°. 
Med Hensyn paa Saltgehalten i Overfladevandet hen- 
vises til Kartet No. I, hvori Andes indtegnet en større 
Del af do Tal. der fremgaa som Middel af de efter Chlor- 
og Egenvægtsbestemmelserne beregnede Værdier for Salt- 
mængden. Efter disse Observationer findes ogsaa optruk- 
ket Grændserne for 3.55, 3.50, 3.45 og 3.40 "/« Salt, saar 
ledes som deres Form maa antages at være i Sommermaar 
nederne. Kartet viser, at den i Syd ind i det norske Hav 
strømmende Varmvandsstrøm fører Vand af temmelig stor 
Saltgehalt, som* i de sydligste Egne paa begge Sider af 
Færøerne gaar op til 3.55 % eller endog derover. Herfra 
gaar Strømmen videre i nordostlig Retning med noget 
lavere Saltgehalt (omkring 3.525 °/ 0 ) indtil lienimod Be eren 
Eiland, hvor den deler sig og sender en Arm mod Øst ind 
i Østliavet og en anden i nordlig og noget vestlig Betning 
land and Jan Mayen there is a vast ridge, and here the 
depth does not reach 1500 fathoms (2743 metres); but 
south and north of that ridge it is much greater, in some 
localities more than 2000 fathoms (3658 metres). Barents' 
Sea, or. the tract of ocean stretching between Novaja 
Zemlja and an imaginary line drawn from Spitsbergen 
to the northern extremity of Norway, is everywhere exceed- 
ingly shallow, the depth in but few places reaching above 
200 fathoms (366 metres). 
The extensive series of observations shows that the 
temperature of the water throughout the part of Barents' 
Sea investigated by the Expedition, saving the most easterly 
and northerly tracts, exhibits everywhere a. temperature above 
zero, from the surface to the bottom, as is also the case 
with the water on- the great Norwegian banks, which, in 
certain localities, extend to a considerable distance from the 
coast. A very different relation rules in the deep western 
section, which, as regards temperature, may be divided into 
two principal tracts, an eastern, with the Gulf Stream, as 
it is called, flowing north, and a western, with the Arctic 
current, -flowing south, along the shores of East Greenland. 
The boundary -line between these two currents extends 
north of Iceland to the island of Jan Mayen, where it 
makes a bend southward and eastward, crossing, in long- 
itude about 3°W., with a north-easterly direction, the 71st 
parallel of latitude. From thence it runs east, and, when 
in longitude about 7° E.. takes a northerly and somewhat 
westerly direction, continuing on past the 80th parallel of 
latitude. 
In the tract of ocean stretching to the east of this 
boundary, the temperature of the surface-water is compara- 
tively high, exceeding even that of the atmosphere in the 
middle of summer; the water, too. some distance below the 
surface exhibits a temperature above zero, the depth at 
which 0° is reached being about 500 fathoms (914 metres), 
from which the. temperature sinks slowly and gradually to 
about — 1.°3, at the bottom. 
In the cold East Greenland current, the temperature 
at the surface is on the other hand exceedingly low. though 
in summer above zero where the water is free from ice; 
0° however is reached at the depth of a few fathoms. 
As regards the amount of salt in the surface-water, 
the reader is referred to Plate I, in which will be found 
most ol the figures representing the mean values, deduced 
from the chlorine and specific gravity-determinations, for 
the proportion ol salt. In Pl. I. too, are laid down curves 
constructed lrom these results, to show the limits of dis- 
tribution lor the following percentages of salt: 3.55, 3.50, 
3.45, and 3.40, ås they may be assumed to extend in the 
summer months. The warm current, flowing from the south 
into the Norwegian Sea, brings with it, as shown by the 
Plate, an indraught of water containing a comparatively large 
amount ol salt, the maximum percentage, upwards of 3.55. 
being reached in the most southerly tracts, along the eastern 
and western shores ol the Feroe Islands. From thence, 
with a slightly reduced amount of salt (about 3.525), the
