300 Favnes Dyb. Varmegradernes Omraade er meget
indskrænket, men rækker ned til 400 Favne. Mod Vest
indtage Isothermerne en næsten vertical Stilling. De
indeslutte et Maximum af Varme paa over 3°, der ligger under
Overfladen.
Tversnit XXV gaar langs den 80. Breddegrad
udenfor Nordvest-Spidsbergen. Den højeste Varme findes under
Overfladen og naar 3° i 100 Favnes Dyb. Varmegrader
række til 400 Favnes Dyb. Dette er det nordligste Tversnit,
Tversnit XXVI gaar fra Spidsbergens Sydkap over
Beeren-Eiland til Hammerfest. Det viser Temperaturens
Fordeling i den vestlige Del af Østhavet. Den højeste
Temperatur træffes i Overfladen udenfor Nordkap, hvor
den er over 5°. De lavere Isothermer helde mod Norge
paa en meget jevn Maade. Under den norske Kyst er det
saaledes i alle Dybder varmere end söndenfor Beeren-Eiland,
men overalt er der paa denne Strækning Varmegrader.
Mellem Beeren-Eiland og Spidsbergens Sydkap se vi ved Bunden
den iskolde Kile, der kommer fra Storfjorden, og et
Maximum af Temperatur paa over 2° i omkring 60 Fv. Dyb.
Tversnit XXVII gaar fra Vardø mod NE til Novaja
Senilja (74° N. Br.). Det viser Temperaturens Fordeling
i den østlige Del af Østhavet. Alle Isothermer helde mod
Norge. Fra Vardø til den 36. Længdegrad er der
Varmegrader ved Bunden. Østenfor er der Kuldegrader, hvilke indtage
de dybere Lag og blive herskende udenfor Novaja Senilja.
Tversnit XXVIII, PI. XIV, gaar langs Greenwichs
Meridian fra 61° (Shetland) til 78° N. Bredde.
Overfladens Temperatur aftager stadig mod Nord indtil den 77.
Breddegrad. Mellem 70° og 73° N. Br. se vi Overfladen
lidt koldere end Vandet i 100 Favnes Dyb.
Nulgradsiso-thermen naar uncler 64° Bredde kun 280 Favne, men gaar
herfra mod Dybet, indtil den mellem 70° og 71° naar ned
over 600 Favnes Dyb, for videre mod Nord at stige, indtil
den ved 77" naar Overfladen. Et løsrevet Stykke med
svag Varmegrad findes i 100 Favnes Dyb paa 77° til 78°.
Isothermen for — 1°, der ved 63°—64° ligger lidt dybere
end 800 Favne, sænker sig til 1000 Favne ved 65°—66°,
stiger til 870 Favne ved 68°, synker til henimod 1000
Favne lidt nordenfor 70u og stiger derfra op mod
Overfladen under 74° Br. Fra 74° til 73° skyder den i de øvre
Lag en Kile sydover og fra 76° til 77° en lignende
nordover. Nordenfor 76° se vi den i større Dybder danne en
næsten sluttet Curve omkring Varinegradsniaximumet.
Mellem den 70. og 71. Breddegrad er der ved Bunden et
Varmeniaximum, hvor Temperaturen ikke gaar under
— 1°.17. Mellem 66° og 69° er Bundtemperaturen lavere
end — 1°.3. Mellem 73° og 76° indtages de dybere Lag,
under 1000 Favne, af et. Temperaturminimum paa — 1°.6.
of close upon 300 fathoms. The temperatures above 0°
extend over a very contined space, which reaches however
down to 400 fathoms. Towards the west, the isotherms
have an almost vertical position. They inclose a maximum
of heat, upwards of 3°, which lies beneath the surface.
Section XXV extends along the 80th parallel of
latitude, oft’ the north-west coast of Spitzbergen. The
highest temperature occurs beneath the surface, and reaches
3°, at a depth of 100 fathoms. Temperatures above
0° extend down to 400 fathoms. This is the most
northerly transverse section.
Section XXVI extends from the southern extremity
of Spitzbergen across Beeren Eiland to Hammerfest. It
shows the distribution of temperature throughout the western
tract of the Barents Sea. The highest temperature occurs
at the surface, off the North Cape, where it reaches
upwards of 5°. The lower isotherms incline towards Norway,
very gradually. In immediate proximity to the coast of
Norway, the water in all depths is accordingly found to
be warmer than south ot Beeren Eiland. but degrees above
0" we meet with everywhere throughout that tract.
Between Beeren Eiland and the southern extremity of
Spitzbergen, occurs the ice-cold wedge at the bottom that has
its origin in the Storfjord, and also a maximum of
temperature, reaching more than 2°, at a depth of about 60
fathoms.
Section XXVII extends from Vardø towards the
NE as far as Novaja Senilja (lat. 74° N). It shows
the distribution of temperature throughout the eastern
tract of the Barents Sea. All the isotherms incline
towards Norway. From Vardø to the 36th degree of
longitude, the temperature is above 0° at the bottom. To the
east, a temperature below 0° occupies the deeper strata,
and prevails off Novaja Senilja.
Section XXVIII, Pl. XIV, extends along the
meridian of Greenwich, from 61° (Shetland) to 78" N. The
surface-temperature decreases steadily towards the north, up
to the 77th parallel of latitude. Between latitude 70° and
73" N, the water at the surface is somewhat colder than
at a depth of 100 fathoms. The isotherm for 0° reaches
down at the 64th parallel of latitude to only 280 fathoms,
but descends from thence towards the deep, till, between
70° and 71", it is met with at a depth of more than 600
fathoms, after which it rises towards the north, till, at 77°,
it reaches the surface. An isolated patch, with a
temperature a little above 0°, occurs at a depth of 100 fathoms,
in lat. 77"—78°. The isotherm for — 1", which at 63"—64"
lies somewhat deeper than 800 fathoms, sinks to 1000
fathoms at 65"—66°, rises to 870 fathoms at 68", sinks to
close upon 1000 fathoms a little to the north of 70°,
rising up from thence towards the surface at the 74th
parallel of latitude. From 74" to-73", it sends out a wedge
southwards in the upper strata, and from 76° to 77" a
similar one northwards. North of 76°, in greater depths,
it forms a well-nigh closed curve round the maximum of heat,
with a temperature above 0°. Between the 70th and 71st
parallels of latitude occurs at the bottom a maximum
