From the ocean south of Iceland there are also measurements 

 to hand carried out on board the "Thor" (Nielsen, 53).

There are moreover some notes, given by Knudsen (44), on 

 the temperature and salinity of the surface-water of the ocean south 

 of Iceland. They are based upon the measurements carried out on
