No. 24 og 25 ligge paa den lidt bølgeformede Banke.
No. 26 ligger paa en "Fiskebank", hvis Top ligger i
Længden 11° 26’ E. Paa Vestsiden af denne Bank ere
Bundtemperaturerne over 6°.6, men paa Østsiden gaa de ned til
under 6°. No. 27 ligger i Dønnes-Fjorden vestenfor
Døn-nesøen. Temperaturen har et Minimum i 80 Favnes Dyb
og er constant 6° fra 100 Favne til Bunden i 175 Favne.
Udenfor Mundingen af Vestfjorden har "Hansteen"
følgende 3 Temperaturrækker.
Nos. 24 and 25 lie on the sligthly undulating bank.
No. 26 is located on a "fishing-bank," the summit of which
lies in long. 11° 26’ E. On the west side of this bank, the
bottom-temperatures reach ’upwards of 6°.6, but on the east
side they sink below 6°. No. 27 lies in the Dønnes Fjord,
west of the island of that name. The temperature has a
minimum at a depth of 80 fathoms, and is constant at 6°
from a depth of 100 fathoms to the bottom, in 175 fathoms.
Off the mouth of the Vestljord, the "Hansteen" has
the following 3 serial temperatures: —

Imellem Røst og Bodø strækker sig en Forhøjning i
Havbunden, der paa dens dybeste Parti sænker sig til 120
Favne under Havfladen og begrændser Vestfjordens Bassin.
No. 28 ligger udenfor (söndenfor) denne Ryg. No. 29
ligger i en Fordybning udenfor Mundingen af Saltenfjorden,
ogsaa söndenfor Ryggen. No. 30 ligger paa Ryggen, ved
dens dybeste Parti. Paa alle 3 Steder ere
Bundtempera-turerne forholdsvis høje. Paa et Punkt, noget i Nordost
for No. 30, hvor Dybden er 150 Favne, niaaltes
paaNord-havs-Expeditionen d. 22. Juni 1877 (Station No. 148) i
100 Favne 4°.3, i 140 Favne 5°.0; den 18. August samme
Aar fandtes i 100 Favne 5°. I og i 140 Favne 5°.8 (Station
No. 254). Temperaturen var saaledes i mindre end 2
Maaneder steget 0°.8. Et Temperatur-Minimum fandtes i 60
Favnes Dyb. Forholdene i 1877 ere saaledes temmelig
afvigende fra dem, som paa nærliggende Sted fandtes i 1885.
Den inderste Del af Vestfjorden danner et Dybbassin
paa indtil 350 Favnes Dyb. Her fandt vor Expedition i
Juni 1878 (Station No. 255) i 100 Favnes Dyb 5°.9 og i
300 til 340 Favnes Dyb 6°.5. Udenfor Lødingen (68° 24’
N. Br. 16° 1’ E. Lgd.) har Telegrafinspectør Lie, ved
Foranstaltning af Opsynschefen ved Lofotfisket, Captein i
Marinen N.Juel, maalt i Aarene 1879 og I88O Temperaturen
paa Dybet indtil 100 Favne i Maanederne Maj til
næstfølgende Januar. Disse Observationer skal jeg nedenfor
meddele i større Omstændelighed. I begge Aar fandtes her,
hvor Vestfjorden ender, i 100 Favnes Dyb en Temperatur,
der kun varierer fra 6°.2 til 6.°5 og i Gjennemsnit er 6°.4.
Den svarer saaledes nærmere til det dybeste Lags
Temperatur end til Temperaturen i 100 Favne i Vestfjorden i 1878.
Between Røst and Bodø stretches an elevation of the
sea-bed, which, in its deepest part, sinks to 120 fathoms
beneath the surface, and limits the basin of the
Vest-fjord. No. 28 is located off (south of) this ridge. No.
29 lies in a depression off the mouth of the Saltenfjord,
also south of the ridge. No. 30 lies 011 the ridge — its
deepest part. I11 each of these localities the
bottom-teni-peratures arc comparatively high. At one point, a little
to the north-east of No. 30, where the depth reaches 150
fathoms, was registered 011 the North-Atlantic Expedition,
22 June 1877 (Station No. 148), in 100 fathoms, 4°.3, in
140 fathoms 5°.0. O11 the 18th of August — same year —
was found in 100 fathoms 5°.l, and in 140 fathoms 5°.8
(Station No. 254). The temperature had consequently risen
in less than 2 months as much as 0°.8. A
temperature-minimum was found to occur at a depth of 60 fathoms.
Hence, in 1877, the temperature-relations deviate very
considerably from those observed in an adjacent locality in 1885.
The inner part of the Vestfjord constitutes a deep
basin, reaching clown as low as 350 fathoms. Here the
North-Atlantic Expedition registered in June 1878
(Station No. 255), at a depth of 100 fathoms, 5°.9, and
in 300 to 340 fathoms 6°.5. Off Lødingen (lat. 68° 24’ N,
long. 16° 1’ E), Mr. Lie, Inspector of Telegraphs,
measured, at the requisition of Capt. N. Juel, R. N., Chief
Inspector of the Lofoten Fishery, in the years 1879 and 1880,
the temperature to a depth of 100 fathoms from the month
of May to the month of January in the following year.
These observations I shall communicate below in greater
detail. Both years was found here, at the point where the
Vestfjord terminates, with a depth of 100 fathoms, a
temperature varying only from 6°.2 to 6°.5, and averaging 6°.4.
