Ifølge Planen for Bearbejdelsen af det videnskabelige Ud- 

 bytte. der erhvervedes under den norske Nordhavs-Ex- 

 peditions 3 Togter i Aarene 1876 — 78. har der i forskjellige 

 Brancher i inden- og udenlandske Tidsskrifter været leveret 

 forelobige Oversigter, der kortelig Kave refereret de væsent- 

 ligste Resultater. . enten saaledes. som disse lia ve foreligget 

 etter Slutningen af hvert enkelt Togt. eller som et samlet 

 Resume af dem alle. 



For de under Expeditionen erhvervede Dybvandsfiskes 

 Vedkommende ere to saadanne foreløbige Oversigter ud- 

 komne. begge trykte i ,,Forhandlinger i Yideiiskabs-Selskabet 

 i Christiania Aar 1878-. 1 Af disse Oversigter. der ikke 

 vare ledsagede af Figurer, udgjør denne General-Beret- 

 ning en udførligere, og i flere Henseender suppleret og 

 corrigeret Bearbeidelse. 



Medens Udbyttet a f Evertebraterne allerede under 

 de 2 første Togter, i 1876 og 1877. viste sig at være 

 ganske betydeligt. og frembød Former af den største Inter- 

 esse, vare de samtidig! indsamlede Fiske forholdsvis faa- 

 tallige. Dette havde væsentlig sin Gruud deri. at de 

 Apparater, der i de nævnte Aar anvendtes til Skrabning 

 eller Optagelse af Bundprøver. ikke vare synderlig tjenlige 

 til disse Dyrs Erhvervelse. Især var dette Tilfældet under 

 det første Togt ; Undersøgelserne foregik desuden dette Aar 

 næsten udelukkende paa de store Dybder i den iskolde 

 Area mellem Norge og Island, hvor maaske idethele- 

 taget Fiske-Faunaen er fattigere, end paa flere nordligere 

 Localiteter. hvor Strømningsforholdene bevirke en rigeligere 

 Adgang til Føde. skjønt Bundtemperaturen kan være lige- 

 saa lav. Noget større blev Udbyttet Sommeren 1877. da 

 "Undersøgelserne bleve drevne paa det noget grundere Vand. 

 dels paa Bankerne udenfor de norske Kyster, dels i Trak- 

 terne a f .Tan Mayen.

Pursuant to the resolution for arranging and pub- 

 lishing the fruits of the Norwegian North-Atlantic Ex- 

 pedition, from voyages undertaken in the years 1876. 

 1877, and 1878, preliminary papers, connected with divers 

 branches of scientific research, have appeared in Norse and 

 foreign journals, giving a summary of the chief results 

 attained, either progressively, as set forth at the termination 

 of each separate voyage, or comprehensively, as a brief 

 resume of them all. 



The deep-sea. fishes collected on the Expedition form 

 the subject-matter of two such preliminary memoirs, both of 

 which will be found in ''Forhandlinger i Videnskabs-Selskabet 

 i Christiania Aar 1878. '^ These sj'noptical papers — which 

 were not furnished with figures — have been subjected to a 

 careful revision, and, with the aid of additional data, expanded 

 into the present section of the General Report. 



For the invertebrate animals, the results even of the 

 two first voyages, in 1876 and 1877. proved very considerable. 

 yielding forms of the greatest interest, whereas the number 

 of fishes obtained was comparatively small. The chief reason 

 of this, however, lay in the fact of the dredging-apparatus 

 then employed not having been well adapted for securing 

 specimens of these animals. Such showed itself the case 

 more particularly on the first voyage; the investigations. 

 too, in 1876 were carried on almost exclusively at great depths, 

 in the cold area between Norway and the shores of Iceland, 

 where the marine fauna is less rich perhaps than in some locali- 

 ties further north, which the effect of ocean currents has secured 

 a more abundant influx of food, though the temperature at 

 the bottom may be" equally low. In the summer of 1877 the 

 results were somewhat greater, the Expedition extending its 

 investigations to shallower water, partly on the banks off 

 the Norwegian coast, and partly in the region adjoining 

 Jan Mayen.
