østlige Del af Tverryggen og tilsidst Banken udenfor Spids-

meget jevn. Paa Vesteraalseggen komme Kuldegraderne

Tversnit XXX gaar langs Meridianen 10° W. f. 
Greenwich fra 60° til 759%.N. Br. Det overskjærer Færø- 
Island-Ryggen, Jan Mayen Renden, Vestfoden af Jan Mayen 
og Grønlandshavet. Paa Island-Færø-Ryggen sees Over- 
gangen fra den atlantiske til den nordiske Temperaturfor- 
deling. Her ligge de varmeste Vandlag under Overfladen. 
I Jan Mayen-Renden sees det koldeste Vand at kaste sig 
over paa Sydsiden. Under Jan Mayen er det merkelig 
varmere paa Sydsiden end paa Nordsiden.

Section XXIX, Pl. XIV, extends along the meridian 
10° east of Greenwich, from lat. 64° (Fosen) to lat. 80° 
(Spitzbergen) N. It passes first across the Norwegian 
coastal banks, off Helgeland, then across the Vesteraalseg, 
the Lofoten Deep, the eastern part of the Tranverse Ridge, 
and finally the bank off the west coast of Spitzbergen.

Section XXX extends along the meridian 10° west 
of Greenwich, from lat. 60° to 75° N. It crosses the 
Feroe-Iceland Ridge, the Jan-Mayen Channel, the western 
base of Jan Mayen, and the Greenland Sea. On the 
Teeland-Færoe Ridge is seen the transition from the Atlantic 
to the North Ocean distribution of temperature. Here, 
the warmest strata of water lies beneath the surface. In 
the Jan-Mayen Channel, the coldest water keeps to the 
south side. Off the coast of Jan Mayen, the water is ap- 
preciably warmer on the south than on the north side.

A. Horizontal Distribution of Temperature. 
To show the distribution of thetemperature horizon-

Pl. XVI shows the mean temperature for the year, 
represented by means of isotherms for each degree Celsius. 
The construction of the Map will be explained more 
fully further on.
