Længdesnit i Profil XXI, PI. XLI. og som sees i sin hele
rdstrækning langs Bunden paa Pl. XXV.
Pl. XIX viser Temperaturens Fordeling i 300
Favnes Dyb. Vestenfor Island støder endnu 5° til Banken.
1 Sydost for Island findes 7" og paa Sydvestsiden of
Wy-ville-Thoinson-Ryggen r<" til 9". 1 Fan-o-Shot land-Rendens
sydligste Del have vi et Toniperatur-Maximuui paa over 5°,
omgivet paa Nord- og Sydsiden af koldere Vand. Langs
Norges Kystbanker optræde lignende Maxima paa over 5°
udenfor Romsdalskysten (03° X. Br.) og udenfor Røst
(G7°.5 X. Br.). Varme Tunger strække sig mod Vest
mellem Lofoten og .Tan Mayen og mod Xord langs Banken
udenfor Vest-Spidsbergen (1° ved 80° N. Br.). Koldere
Vand ved Banken sees under 7°—8° E. Lgd., G0°.5 N. Br.
og Vest for Beeren-Eiland, udenfor hvilket der er et
Maximum paa 2°. Strax nordenfor dette sees den kolde Straale
fra Spidsbergens Storfjord. Østhavets Bund ligger højere
end 301) Favne.
De kolde Tunger fra Grønlandshavet gjenfindes.
Nulgrads Tungen fra Jan Ma,yen-Renden udstrækker sit
Omraade helt til den nordvestre Side af Fan’ø-Shetland-Renden
og henimod Nordsøbanken (62"..") X. Br.) og de norske
Kystbanker (3° 4° E. Lgd.).
Under 60° N. Br., udenfor Vesteraalen, ligger en
Tunge med over 4°. der, som anført, fortsættes mod Vest.
Isothermen for 3° rækker, under 70" N. Br., helt Vest til
1" \V. Lgd. Isothermen for 2" udskyder, som Fortsettelse,
en Tunge mod Syd, parallel med den iskolde Tunge i
.Ian Maven-Renden. Vestsiden af Jan Maven-Banken har
endnu Varmegrader.
Pl. XX viser Temperaturens Fordeling i 400 Favnes
Dyb. Nordhavet er i dette Dyb ganske adskilt fra
Atlanterhavet. I dette sidste tindes 7°—8" opunder
Islands-banken og Wyville-Tliomson-Ryggeii. Paa don anden Side
af denne sees i Midten af Færø-Shetland-Rendeh en liden
Tunge med Varmegrader, ellers er hele Renden og Havet
nordenfor til c. Gl0 N. Br. fyldt med iskoldt Vand.
Enkelte Steder optræder under Banken endog — 1°.
Det er, i dette Dyb, paa højere Bredder, at man
har Varmegradernes Region. Fra et Maximum paa over
3°. der ligger klos udenfor Vesteraalen, skyde sig
Varmetunger med Vest og mod Nord. De første bøje østenfor
.Tan Mayen mod Syd og, som det synes, mod Sydost,
cul-minerende i et Maximum paa 1°.G i Station 9G. Lidt
hengere Nord have vi en Tunge mod Syd i Retning af det
Parti, hvor Banken løber tvers paa Meridianen (Snit 8"E.
PI. XXVI). Fra Vesteraalen af forfølge vi Varmetunger
nordover udenfor Bceren-Eilands og Vestspidsbergens
Banker, med koldere Vand inde ved Banken, lige til 0° ved
80" Bredde. Strax Nord for 75° N. Br. spores den iskolde
Tunge fra Storfjorden. De kolde Tunger fra Grønlands-

Pl. XIX shows the distribution ol’ temperature at a
depth of 301) fins. West of Iceland. f>" is still found close to
the bank. South-east ol’ Iceland, we have 7", and on the
south-west side of the Wyvilie-Thomson Ridge 8°—9°. In
the most southerly part of the Færoe-Shetland Channel,
there is a teiuperature-maximum of more than f>°,
surrounded on the north and south by colder water. Along
the Norwegian coastal banks occur similar maxima,
reaching more than 5°, viz., off the Romsdal coast (lat. 03° X) and
off Røst (lat, G7°.5 N). Warm isothermal tongues extend
westward between Lofoten and Jan Mayen, and
northward along the baille off West Spitzbergen (1° in lat. HO»
N). Colder water is met with on the bank in long 7" lo
8" E, lat. 66°.5 X, and west of Beeren Eiland, off which
occurs a maximum of 2". Immediately to the north of
this maximum, flows the cold stream from Spitzbergen’s
Storfjord. The bottom of the Barents Sea lies higher
than 300 fathoms.
The cold isothermal tongues sent off from the Greenland
Sea are again met with. The zero-tongue from the
.Jan-Mayen Channel extends its limits to the north-western
side of the Færoe-Shetland Channel, and almost as far as
the North-Sea Bank (lat. 62°.5 N) and the Norway coastal
banks (long. 3»—4" E).
In lat, 69° N, off Vesteraalen. lies an isothermal tongue,
with upwards: of 4° of heat, which, as previously stated, extends
farther towards the west. The isotherm for 3° reaches, in lat.
70°, as far as long. 1° W. The isotherm for 2° sends off. in
continuation, a tongue southward, parallel to the ice-cold
tongue in the Jan-Mayen Channel. The western slope of
the Jan-Mayen Bank still exhibits a temperature above 0".
Pl. XX shows the distribution of temperature at a
depth of 400 fathoms. At this depth, the North Ocean is
entirely cut off from the Atlantic. The latter has 7" 8"
in close proximity to the Iceland Bank and the Wyvi
lie-Thomson Ridge. On the opposite side of the latter, a
small isothermal tongue, with a temperature a little above
0" occurs in the middle of the Færoe-Shetland Channel,
but with this exception the whole channel and the sea
without to well-nigh lat. (51° .X. is tilled with ice-cold water.
In a few places, we have off the bank even 1".
It is throughout this deep, in higher latitudes, that
the region with temperatures above 0" is mot with.
From a maximum of more than 3°, lying close off
Vesteraalen, the isothermal tongues of heat strike out west ami
north. The former bend off east of Jan Mayen towards
the south, and also, it would seem, towards the south-east,
culminating in a maximum of 1".G, at Station 9G.
Somewhat farthei north, there is a tongue stretching southward,
in the direction of the tract where the bank extends
perpendicular to the meridian (Section 8° E. Pl. XXVI).
From Vesteraalen. we can trace isothermal tongues of
heat northwards, off the Beeren-Eiland and the
West-Spitzbergen Banks, with colder water in immediate proximity
