1809] Some HydrogTaphical Results. IS 



The periocl from Janiiary to April is also characterizcd by a sinking 

 of the snrface temperature. On May 5th was founcl the spring 

 minimum at about 20 m. (1°,9 C). 



In order to get a qiiantitative idea of the infliience of the Gulf 

 Stream on the temperature of the deep layers of the fjords, I have 

 untertaken some messurements in closed basins. One of the fjords 

 that from the Vestfjord penetrate into the island of Hinnø, is the 

 Øgsfjord. By a submersed plateau from which arise a number of 

 small islands and holmes, this fjord is separated from the deep 

 channel of the Vestfjord. On March lOth 1899 I thus found at. 

 the mouth of the Øgsfjord at 220 m., t. = l^,? C. and s. = 33,40. 

 On March 14th the conditions in the Øgsfjord were again examined. 

 At the depth of 200 m. I then found t. = 1,4, s. = 33,33. Another 

 fjords that penetrates into the Hinnø is the Kanstadfjord. Here 

 the bottom conditions are of a somewhat different character, not 

 the whole fjord being shut up, but only the inn er part, which by 

 a submersed sill, called the Riff, is seperated from the rest. Inside 

 this sill was messured on March Uth 1899 at 90 m., t. = P,6,. 

 s. = 33,48, and on the same day outside the sill, at 90 m., t. = 

 4,4, s. = 34,06.— The continuation of the Vestfjord is called the 

 Ofoten fjord, which again has several branch-fjords. At the mouth 

 of. the Ofotenfjord, Febr. 9th 1899 showed at 550 m. (bottom) 

 t. = 6,3, s. =^ 35,14. That Atlantic conditions were prevailing 

 here is obvious enough, and the strong influence of the Gulf stream 

 water could be perceived as far as the Rombak fjord, where 

 temperature (Febr. 8th 1899) was 6^0 from 120—310 m. (bottom), 

 while salinity in that layer varied between 34,45 and 34,82 7oo. 

 At the depth of 100 m. t. was = 4^,8 and s. = 34,01, while at 

 the same time, inside the channel connecting Rombaksbotten with 

 the Rombakfjord, at 110 m. (bottom) temp. was 0^,6 and salinity 

 33,37. Fven as far up as in the Rombak fjord we can, in the high 

 temperature and great salinity of the bottom water, trace the strong 

 pulsation of the Gulfstream. The same cannot, however, be said 

 of another branch-fjord, lying nearer to the Ocean, the one called 

 Skjomen.
