The Station of April 5, 1882, was about 22 kilometres west of Dr. 
Hjorts Station 64 of Sept. 6, 1900 (the Michael Sars). Hjort’s salinities, at 
this place, varied between 35:02 °/oo, at the surface and 20 metres, and 
35‘10 900 at 100 metres. 
His temperatures were the following:

Hjort’s Station 64 was taken near the time of temperature maxi- 
mum for de upper water-strata, and 48 days later in the season than 
Mohn’s Station 304. It is, therefore, natural that there should be a 
greater difference between his summer- and the writer’s winter tem- 
peratures. But the difference is still too great to be explained simply 
by cooling during the winter; there has in addition probably been some 
great displacement of the cold surface waters towards the east during 
the winter and spring of 1882, since the ice was met with much farther 
east than is generally the case. Whether “Bottom-Water” actually was 
being formed at the surface at my Station of April 5, 1882, cannot be 
decided as the salinity is unknown; it is indeed not impossible but it 
seems more probable that the low temperatures down to 94 metres 
belonged to a layer of less saline water, and that higher temperatures 
would have been met with in the water underlying. 
But howsoever this may be the above vertical temperature series 
which are also the only ones existant from this region of the sea for 
winter and early spring, indicate what great amplitudes may occur there 
in the upper water-strata, between summer-maximum and winter-minimum.
