Fra det Punkt 1 Østhavets Stromaxe, hvor h, = 0.05

Punkt setter jeg hastigheden w, = 0.04 m. p. S. (Middel af

Punkt setter jeg Hastigheden lig 0.13 m.p.S. Kartet, PI.

Men Nærheden af Land og den Omstændighed, at den 
nævnte Værdi er en Maximumshastighed, tillader ikke at 
sætte den virkelige Hastighed saa stor.

Such a section has been drawn in the direction of 
the North Cape from the point in the current-axis at which 
h, =0.1 metre. We have here a= 280 kilometres, H=0.8 
metre, h, = 0.1 metre, and get X, = 433 kilometres, with 
the corresponding velocity U, = 0.26 metre per second. 
A similar transverse section was drawn from the point 
where h, = 0.3 m. to the Murman coast, east of the Rybatschi 
Peninsula. With a=325km., H=0.8m., and h, =0.3 m., 
we get X, = 838 kilometres, and U, = 0.137 metre per second. 
In like manner towards Novaja Semlja from the point 
where h, = 0.2 metre. Here a is = 750 kilometres, H= 0.8 
metre, X = 1500 kilometres, and U, =0.075 metre per second. 
From the point in the current-axis of the Barents 
Sea at which h, = 0.05 metre, a normal line has been 
drawn to South Cape, Spitzbergen. At the former point, I 
put the velocity, «, =0.04 m. per sec. (mean of 0.013, in 
the current-axis, and 0.07, from Pl. XXXII). At the 
latter point, I take the velocity equal to 0.13 metre per 
second. The map, Pl. XXXII, gives here a velocity of 
more than 0.14 metre per second. But the close proximity 
of land and the circumstance that the said value is a 
maximum-velocity, will not allow of putting the true velocity 
so high. 
The distance, a, between the points is 860 km. With

hence X,= 534 km., and, with U,=0.13, the height at 
South Cape, H=0.498 metre. 
According to this result, the height of the wind-surface 
at the coasts. of Spitzbergen must be put at 0.5 metre 
above the surface of level through B or A. 
From B a normal line has been drawn along the 
current-axis west of Spitzbergen. Judging from the course 
of the current-lines, the point of section between this norma
