The annual range exhibits a maximum at the surface, 
a secondary minimum in 5 fathoms, a secondary maximum 
in 20 fathoms, and diminishes from thence gradually to 
the bottom, sinking at a depth of 100 fathoms to 097. 
Botb at Lødingen and in the Altenfjord, the annual 
variation ‘of the sea-temperature proceeds in the singular 
that the temperature, at the outset of the year, 
increasing steadily to a depth of

100 fathoms, 
From April to autumn, 
deeper strata, above 100 fathoms, is still found to rise with 
the depth, whereas in the upper strata it diminishes with 
the depth, the surface becoming warmer and warmer. Hence, 
at a certain depth we get a minimum of temperature, which 
higher up and in summer deeper down. In 
‘autumn, during the months of September October, 
the temperature will possibly be found to fall slowly and 
steadily from the surface to the bottom. Then follows a 
period during which the surface becomes steadily cooled,
