Pl. XVIII viser Temperaturens Fordeling i 200

Tunger sig mod Nord (69 og 59), ligesaa op mod Islands 
Banker i Sydost for dette Land, paa Vestsiden at Færø- 
Banken og paa Nordvestsiden af Shetlandsbanken. Disse 
fortsætte, med aftagende Varmegrader, langs Norges Kyst- 
banker, til hvilke de læne sig, uden at koldere Vand ligger 
imellem. Videre kunne de forfølges ind 1 den sydlige 
Del af. Østhavet (2°) og langs Vestbanken udenfor Beeren- 
Eiland og Spidsbergen (2° ved 80° Bredde). Sidegrene 
udgaa mod Vest henimod Island, med et Varme-Maximum 
af 4°.3 (Station 52), og omkring 70° Bredde henimod Jan 
Mayen, samt under 78" Bredde fra Spidsbergen mod Vest. 
De kolde Tunger findes i det Hele taget paa samme 
Plads som i 100 Faynes Dyb, fra det nordlige Østhav 
langs Østsiden af Beeren-Eiland-Banken, fra Grønlands- 
havet mod Sydost i Retning af Vesteraalen, østenfor Jan

af Temperatur ved Bunden (4°.8 og 4°.9, Stat. 121 og 
122, 1 192 og 201 Favnes Dyb); østenfor og vestenfor ere 
højere Temperaturer (69.2, Stat. 120, 190 Fv.; 59.6, Stat.

Minimum, der sees paa Kartet Pl. XVIIT og paa Bund- 
temperatur-Kartet Pl. XXV, er en Straale af koldere 
Vand, der nordenfra trænger fra dybere Lag opover Ban-

grees above 0°, north of the Færoe Islands, where it sends 
off an arm towards the east and another arm towards the 
south, the latter filling the north-west side of the Færoe- 
Shetland Channel. In Denmark Strait, an ice-cold isothermal 
tongue extends along the coast of Greenland, towards the 
south-west. 
Pl. XVIII shows the distribution of temperature at 
a depth of 200 fathoms. Along the west coast of Iceland, 
warm isothermal tongues (6° and 5°) strike off towards the 
north, and likewise towards the Iceland banks lying 
east of that island, on the west side of the Faeroe Bank, 
and on the north-west side of the Shetland Bank. These 
tongues continue their course, with diminishing tempera- 
south- 
ture, along the Norway coastal banks, towards which 
they incline without having colder water between. They 
admit, too, of being traced farther, viz., into the 
southern part of the Barents Sea (2°), likewise along 
the western bank off Beeren Hiland, and off Spitzbergen 
(2°, lat. 80°). Lateral branches extend westward towards 
Iceland, with a maximum of heat, 4°.3 (Station 52), 
about the 7Oth parallel of latitude, towards Jan Mayen, and 
on the 78th parallel of latitude, from Spitzbergen towards 
the west. 
The cold have as a rule the 
same position as they are found to occupy at a depth of 100 
fathoms, viz: from the northern tracts of the Barents Sea 
along the eastern side of the Beeren-Eiland Bank; from 
the Greenland Sea towards the south-east, in the direction of 
Vesteraalen; east of Jan Mayen (warm tongue westwards); 
through the Jan-Mayen Channel; east of Iceland, with 
isothermal tongues 
continuation along the northern part of the Iceland-Feroe 
Ridge, north of the Færoe Bank, east of that bank on the 
north-west side of the Færoe-Shetland Channel, and towards 
the Norway coastal bank lying south of lat. 65° N. In 
the north-western part of Denmark Strait, ice-cold water 
occupies the greater area. 
In lat. 66° 35’ N, long. 7° 50’ E, the Norway coastal 
bank extends W—E, whereas south and north it extends 
S—N. Here we have a minimum of temperature at the 
bottom (4°.8 and 4°.9, Stats, 121 and 122, at a depth of 
192 and 201 fathoms); to the east and west occur higher 
temperatures (6°.2, Stat. 120, in 190 fms.; 5°.6, Stat. 202, 
in 246 fms.), also to the north at the same depth. This 
minimum, shown in the map, Pl. XVIII and in the Map 
of Bottom-Temperatures, Pl. XXV, has its origin in a 
stream of colder water that makes its way from the north 
and from the deeper strata up the slope of the bank. The 
relation will be seen by observing the vertical section that 
extends along the meridian 8° EK, given Pl. XXVI, mm 
which the isotherms for 5°, 6°, and 7° ascend towards the 
south, reaching nearly the edge of the bank. 
In lat. 75°.5 N, long. 15° E, a wedge of ice-cold 
water pierces forward south of the southern extremity of
