Man ser heraf, at Temperaturen i Dybet under 100 
Favne til Bunden ikke er ganske constant, men varierer 
noget, idet den langsomt aftager ovenfra mod Bunden, hvor 
den stadig er funden omkring 50. I 200 Favnes Dyb va- 
rierer den fra 50.0 til 599 og i 100 Favnes Dyb fra 593 
til 69,0. Temperaturen varierer i samme Aar fra Sted til 
Sted (Pommerania) og paa nærliggende Steder (Hansteen) 
fra det ene Aar til det andet. 
Da Indexthermometrene ikke ere istand til at angive 
Temperaturen i Dybet nøjagtig, naar denne baade aftager 
og stiger med Dybet i samme Vertical, men Vendethermo- 
metret registrerer rigtigt, holder jeg mig i den nærmest 
følgende Beskrivelse til de Temperaturer, der ere maalte 
med det sidste. 
I Aakrefjorden -(59° 50’ N. Br.) maalte vor Expe- 
ditions Chemiker, H. Tornge, Sommeren 1884 12 Rekker 
Dybvandstemperaturer.! Af disse fremgaar det, at Tempe- 
raturen paa Dybet fra 100 Fayne til Bunden (storste Dybde 
333 Fy. = 610 Meter) er temmelig constant, 6°.5 til 69,7. 
I Sognefjorden (61° 10° N. Br.) maaltes fra *Han- 
steen” den 9. Juni 1879 mellem Ladvik og Oppegaard 
følgende Temperaturrække.

Fra 100 Favne til 400 Favne aftager Temperaturen 
kun 092, og fra 400 Favne til Bunden i 680 Fayne er 
den absolut constant 69.5. 
I 1872 fandt jeg, noget længere inde i Fjorden, i 400 
til henimod 700 Fayne 692. Nordhavs-Expeditionen fandt 
i 1876 60.6. 
I Throndhjemsfjorden (63° 35’ N. Br.) toges fra 
*Hansteen” følgende Temperaturrækker:

This shows, that the temperature in the deep 
below 100 fathoms to the bottom is not strictly constant, 
but varies somewhat, diminishing’ slowly towards the 
bottom, where it invariably has been found about 5°. At 
a depth of 200 fathoms, it varies from 5°.0 to 5°.9, and at 
a depth of 100 fathoms, from 50.8 to 6°.0. The tempera- 
tures differ in one and the same year from place to place 
(“Pommerania”), and in localities lying comparatively close 
together (*Hansteen”) from year to year. 
The index-thermometers not being able to register the 
temperature in the deep with strict.accuracy when such 
temperature both diminishes and increases with the depth 
in the same vertical, whereas the inverting-thermometer in- 
dicates correctly, I shall confine myself in the following de- 
scription to temperatures measured with the latter instrument. 
In the Aakrefjord (lat. 59° 50’ N) the chemist to 
our Expedition, Mr. H. Tornge, registered during the 
summer of 1884, 12 serial deep-sea temperatures. From 
these it is manifest that the temperature in the deep from 
100 fathoms to the bottom (greatest depth 333 fms. = 610 
metres) is comparatively constant, viz., as 695 to 6°.7. 
In the Sognefjord (lat. 61° 10’ N), the following 
serial temperatures were taken on board the “Hansteen,” 
9 June 1879, between Ladvik and Oppegaard. 
» = 
Meter. Temp. Favne, Meter. Temp. 
(F'ms.) 
7":5 309 565 67.6 
6.8 412 753 6.5 
6.7 515 942 645 
6.7 618 1130 6.5 
B. 680 1244 6.5 
From 100 to 400 fathoms, the temperature diminishes 
only 09,2, and from 400 fathoms to the bottom, at a depth 
of 680 fathoms, it is absolutely constant, viz., 60.5. 
In 1872, I registered, somewhat farther up the fjord, 
at a depth of 400 to close upon 700 fathoms, 69.2. The 
North-Atlantic Expedition found in 1876 a temperature 
of 60.6. 
In the Throndhjemsfjord (lat. 63° 35’ N), the follow- 
ing serial temperatures were taken on board the “Hansteen:”
