the solution of some meteorological and biological problems is closely 
connected with a more accurate knowledge of the watertransport 
through the ocean to our shores. 
GEELMUYDEN found that along the Norwegian coast the behaviour 
of the waterlevel was the same as along the more southern shores 
in question; from the constants he gave for the partial tide Sa, it 
was however not possible to conclude anything about the existence 
of a November-secondary-minimum. 
In the North of Norway the maximum falls later than in the South ; 
the reason why. may perhaps be found, by comparison of table VI 
with the following table, where we calculated the departures from 
the average (1893—1913) of the water-raising power of the wind 
for Bodo.

4. In the preceding pages we think we have demonstrated that 
— at least for a rather great number of years — monthly fluctuat- 
ions in the waterlevel in the North-Sea and the Baltic and halfyearly 
fluctuations in temperature and salinity in the Barents-Sea are origin- 
ated by monthly fluctuations in the velocity of the Equatorial current 
or strength of the North-Hast trade in the North-Atlantic in connect- 
ion with the water-raising power of the wind in the neighbourhood. 
The question arises — and with this we come to the direct appli- 
cation of the preceding theory — is it possible now, to say something 
definite about future fluctuations in meteorological or oceanographieal 
elements in one of the Northern Seas. 
We told already, why we had — by way of introduction at least — 
to make use of fluctuations in the North-East trade and that the 
effect of these fluctuations was felt after about two or three months 
in the northern European Seas. 
We give the following examples. 
Purrersson has found that between Thorshavn and Iceland from 
August 1902—August 1903 the water of Atlantic origin lost 131 
Kilogram-calories daily, from August 1908—August 1904 the daily 
gain was 230 calories. 
_ We have to calculate the mean strength of the trade from June 
1902— 1903 and 1903—1904 and find N 78° E., 2.07 and N 69° E.
