Tid som den Dybde, paa hvilken der kau opereres, er be- 

 tydelig, frembyder Sognefjorden, der i sin ydre Del. uden- 

 for Ladvik, er over 660 Favne dyb. 



Til Udforelsen af den Plan. i denne Del af Sogne- 

 fjorden at foretage de Første forløbige Arbejder. knytter 

 sig den Interesse, som Undersøgelsen af Forholdene i Sogne- 

 fjorden har. navnlig i zoologisk Henseende, i hvilken Ret- 

 ning Fjorden endnu er meget lidet undersøgt, Som bekjendt 

 danner Sognefjorden ved sin ringe Dybde i Mundingen et 

 fra Havet temmelig afsluttet Dybbassih. ■ 



Da iler mellen) det paapegede Puukt af Sognefjorden 

 og Utvær kun er liden Afstand, vil man. naar Yejrforhol- 

 dene falde ugunstige for de magnetiske ( )bservationer paa 

 dette Sted. med Lethed kunne benytte Tiden til Øvelserné 

 i Sognefjorden og saaledes kunne gjøre Regning paa at faa 

 begge disse forberedende Arbejder udførte i en rimelig Tid. 



Etterat man saaledes har vundet det [fornødne Kjend- 

 skab til Apparateme og Øvelse i Brugen af dem i smult 

 Vand, kræves. at man vinder Erfaring i deres Anvendelse 

 paa Søen. i mindre roligt Vejr. De hertil fornødne Øvel- 

 ser antages at kunne, paa den mest frugtbringende Maade. 

 forenes med Udførelsen af Expeditionens egentlige 'Øjerued. 

 ved følgende < trdning af Arbejdet. 



Den dybe Rende, der ligger udenfor den norske Kyst 

 fra Skagerak til Stat, fjerner sig her fra Kysten og synes 

 at udmunde i Ishavsdybet. Der foreligger imidlertid Tem- 

 peraturiagttagélser, der tyde hen paa Muligheden af. at 

 Renden grunder op eller lukker sig. Undersøgelsen af 

 dette Punkt vil derfor udgjøre en passende Gjenstand for 

 Expeditionens Begyndelsesarbejder, Ved at følge Rendens 

 Rund fra Sognefjorden af nordover og undersoge dens For- 

 hold udenfor Stat og Romsdalskysten har man Fordelen af 

 at være paa Soen i et Farvand. hvor Naturforholdene til- 

 stede Apparaternes Anvendelse i forskjellige Retninger og 

 hvor Undersøgelsernes Resultater ville blive baade instructive 

 for Iagttagerne og oplysende tor Videnskaben, og hvor man 

 ikke er hengere fra Land. end at man med Lethed vil 

 kunne soge dette, for at iverksætte mulige Udbedringer 

 eller ønskelige Forbedringer af Apparateme, som Erfaring 

 nia åtte vise det hensigtsmæssigt at foretage. førend man til- 

 iræder ELejsen til fjernere Egne. 



Etterat man saaledes bavde vundet Erfaring i Søen 

 og faaet undersøgt det Parti af de norske Kystbanker. 

 hvorpaa Expeditionens videre Undersøgelser maa støtte sig. 

 maatte man. foråt komplettere Udrustningen for et længere 

 Togt, anløbe en støire Havn. t. Ex. Kristiansund. Her 

 skulde Fartøjet blive :it forsyne med, komplet Udrustning 

 af Kul og Vand, Krpnometernes Stand og Gang bestem- 

 mes og mulige Udbedringer ved Apparateme foretages.

at a considerable depth. is the Sognefjord, which in its 

 outer part. off Ladvik. is 660 fathoms deep. 



Moreover. the selection of the Sognefjord as the tract 

 wherein to commence the preliminary work of the Expedi- 

 tion. would afford a desirable opportunity of scientihcally 

 exploring that region, which has hitherto been but little 

 investigated. in paxticular as regards its fauna. The Sogne- 

 fjord constitutes. by reason of remarkable shallowness at 

 its nioutli. a deep basin well nigh cut off from the ocean 

 without. 



The distance between the above-mentioned point of 

 the Sognefjord and Utvær being comparatively short. when 

 the weather did not admit of continuing the magnetic ob- 

 servations in the latter locality. the time might be advan- 

 tageously employed in the Sognefjord, and there would thus 

 be a ■ fair prospect of completing botb parts of the prelimi- 

 nary work within a reasonable period. 



Knowledge of the apparatus, and the requisite fam- 

 iliarity with their ase in smooth water, having been thus 

 attained, the next step will be- to acquire experience of 

 their application at sea in comparatively rough w.eather. 

 The practice necessarv for this purpose may. it is believed. 

 be easily combined with the main object of the Expedition 

 hy oonducting the work as follows : — 



The deep channel extending along the shores of Norway 

 from the Skagerak to Stat. leaves the coast in this local- 

 ity. and would appear to disembogue into the depths of 

 the Arctic ( )cean. Perhaps. however. inferring from cer- 

 tain temperature-observations, the channel gradually shoals 

 or closes. The clearing up of this question will form a 

 titting subject for the opening work of the Expedition. 

 By following the channel from the Sognefjord northwanls. 

 and investigating its conditions off Stat and the coast of 

 Romsdalen, the Expedition .will secure the advantage of 

 cruising in a tract o'f ocean which admits of a manifold 

 use of the apparatus, and where the results of the investiga- 

 tion must prove alike instructive to the observers themselves 

 and specially promotive of the. interests of science:' more- 

 over, the distance from land being comparatively short. it 

 will. if necessarv. be easy to run in.shore. for the purpose 

 of repairing the apparatus, in case of accident, or of effect- 

 ing such alterations in their construction as may he found 

 desirable, before proceeding to more distant regions. 



Having thus acquired ex])erience in the use of the 

 apparatus at sea. and investigated that portion of the Nor- 

 wegian coastal banks on which the Expedition must base 

 •its subsequent operations. it will he necessarv to touch at 

 one of the larger ports, for instance Christiansund. and 

 there complete the equipinent of the vessel. — viz. by taking 

 in a full supply of coal and water, exainining the chronome- 

 ters. repairing. if daniageil. the apparatus, and effecting 

 anv improvements in their construction that experience 

 may suggest. 



Then. — so soon as the vessel shall in such wisehave been 

 fullv equipped for the cruise (about the end of .lune), the work
