Udenfor Norges Vestkyst, mellem den 59. og 63.
Breddegrad, lober Strømmen nordover med betydelig Fart,
indtil 20 Kv.mil i Døgnet (n.44 ni. p. S.). Her mødes
Strømmen fra Østersøen, fra Atlanterhavet og fra Islands
Østkyst.
Henimod Midten af Havet aftager Strømmens
Hastighed raskt. I en Afstand af 300 Kilometer fra Norges
Kyst er den ikke mere end 5—6 Kvmil.
Nordenfor Stad løber Strømmen langs Norges Kyst
Og fortsætter, følgende Continentet, langs Russekysten og
Novaja Seinlja. Udenfor Nordland er Hastigheden 8 Kvmil
(0.17 m) til 11 Kvmil (0.23 m). Udenfor Finmarkskysten
gaar den op til 16 Kvm. (0.35 m), men længere øst i
Østhavet bliver den igjen ringere (8 Kvm. =0.17 ni). At
den ved Novaja Semlja er saavidt høj, skyldes de ferske
Vandmasser fra Hvidehavet (Dwina) og Petschora.
Langs Spidsbergens Østkyst løber Strømmen mod
Syd. Mellem Spidsbergen og Beeren Eiland tager den
vestgaaende Strøm fra Østhavet en mere nordlig Retning.
Hastigheden er her 6 Kvm. (0.13 m). Paa Strøget ved
15° W Lgd. fandt Capt. Otto1 i Slutningen af November
og Begyndelsen af December med 14 Dages midlere
Vindretning E 8° S, Hastighed 15 m. p. S. (6 Beaufort Skala)
en Strøm, der satte mod N 26° W med en Fart af 11
Kvm. i 24 Timer. Den normale Vindretning og Hastighed
er her (Pl. XXXI) E. lidt nordlig, 4 ni. p. S.
Langs Spidsbergens Vestkyst løber Strømmen med
stor Fart nordover. Efter Kartet gaar Hastigheden op til
17 Kvm. (0.36 m). Strømmen hidrører aabenbart for en
stor Del fra Ferskvandet fra Spidsbergens. Bræer. Da
"Vøringen" dampede nordover paa disse Kanter, viste
det sig, at vi avancerede med en Fart, der var 1 Knob
(24 Kvm. i Døgnet) større end den, som Loggen angav.
Spidsbergstrømmen gaar, under de herskende østlige
Vindes Indflydelse, efterhaanden paa sin venstre Bred over
i den grønlandske Polarstrøni. Større eller mindre Partier
løsrives og flyttes vestover, saaledes som vi have seet i
Profilerne XXIII, PI. XIII og XXVIII, Pl. XIV. Station
No. 351 (77° 49’ N, 0° 9’ AV). I Station No. 303 (75°
12’ N. 3° 2’ E. Tversnit XIX. Pl. XII), der ligger i
Polarstrømnien, fandt Professor Sars, at Overfladens Fauna
var atlantisk.
Den indre, Grønland nærmeste, Del af Polarstrømmen
har sit Udspring i den indre Del af det arktiske Ishav.

Off the West Coast of Norway, between the 59th
and 63rd parallels of latitude, the current sets northward,
with considerable velocity, reaching 20 nautical miles in
24 hours (0.44 m. per see.). Here the currents meet
from the Baltic, from the Atlantic Ocean, and from the
east coast of Iceland.
Towards the middle of the Norwegian Sea, the velocity
of the current diminishes rapidly. At a distance of 300
kilometres from the coast of Norway, it is not more than
5—6 nautical miles.
North of Stad, the current sets along the coast of
Norway, and flows on, following the line of the continent,
along the shores of Russia and Novaja Semlja. Off the
coast of Nordland, the velocity is from 8 to 11 nautical
miles (0.17 m. to 0.23 m.) Off the coast of Finmark, it
rises to 16 nautical miles (0.35 m.); but farther east, in
the Barents Sea, it again diminishes (8 naut. miles = 0.17 m.).
The relatively high rate at Novaja Semlja must be ascribed
to the masses of fresh water from the White Sea (the
Dwina) and the Peschora river.
Along the east coast of Spitzbergen, the current flows
towards the south. Between Spitzbergen and Beeren
Eiland, the current from the Barents Sea, setting west, takes a.
more northerly direction. The velocity is here 6 nautical miles
(0.13 in.). Ill the tract about long. 15° W, Capt. Otto1 found
at the close of November and the beginning of December, with
a forthnight’s mean direction of the wind, E 8° S, and a
mean velocity of 15 m. per see. (6 Beaufort Scale), a current
setting N 26° W, at the rate of 11 nautical miles in 24 hours.
The normal direction and velocity of the wind are here
(Pl. XXXI) east, a little northerly, and 4 m. per see.
Along the west coast of Spitzbergen, the current sets
with great. velocity northward. According to the map, its
velocity reaches 17 nautical miles (0.36 in). This current
obviously originates, to a great extent, in the fresh water
from Spitzbergen’s glaciers. As the "Vøringen" was
steaming northward in these regions, we found her speed
to be greater by 1 knot (24 naut. miles in 24 hours) than
the log indicated.
The Spitzbergen current, acted on by the prevailing
easterly winds, passes gradually with its left border into
the Greenland Polar current. Larger and smaller patches
are disengaged and carried oft’ westward, as seen in
the profiles XXIII, Pl. XIII, and XXVIII, Pl. XIV.
Station 351 (lat. 77° 49’ N, long. 0° 9’ W). At
Station 303 (lat. 75° 12’ N, long. 3° 2’ E, transverse section
XIX, Pl. XII), located in the Polar current, Professor
Sars found the fauna of the surface quite Atlantic.
The inner part of the Polar current, nearest
Greenland, has its origin in the inner basin of the Arctic Ocean.
Parry’s well-known voyage clearly showed that the ice
north of Spitzbergen was drifting southward. On the east
