Man gaar først efter Linien Andø — Jan Mayeil ud i 

 [shavsdybet, undersøger dette og dets Skraaninger paa begge 

 Sider. Omkring Nørdøstenden af Jan Mayen som Centrum 

 foretages nogle kortere Rækker Lodskud mod Nordøst, mod 

 Nord og' mod Nordvest. Paa dette Strøg nemlig, der an- 

 tages at danne den islandske Yulkan-Regions yderste For- 

 bjerg mod Nordost, synes Bunden at falde særdeles brat 

 at' mod Dybet til de nævnte Sider. 



Under den sandsynlige F orndsætning, at Adgangen til 

 Jan Mayen ikke er spærret af Is. forsøges det at lande 

 paa (len til Foretagelse af Undersøgelser i geografisk, geo- 

 logisk, hydrografisk, zoologisk, botanisk Retning m. v. 



En Undersøgelse af Naturforholdene i Havet paa 

 Vest- og Sydsiden af Jan Mayen søges udført. Der er 

 nemlig Grund til at antage. at Jan Mayen er forbundet 

 med Island ved en undersøisk Ryg. 



For at undersøge Forholdene paa Grændsen mellem 

 den varme Overfladestrøm tra Atlanterhavet og den kolde 

 Polarstrøm i Grønlandshavet, opsoges Grønlandsisen i Nord- 

 vest for Jan Mayen. Naar Undersøgelserne langs et Stykke 

 af (Grønlandsisen ere afsluttede. styres til et Punkt omtrent 

 midtvejs mellem Island og Jan Mayen, og derfra undersoges 

 Tversnittet over Ishavsdybet i Retning af Rånen. Herved 

 vil man kunne faa rede paa den formodede undersoiske 

 Ryg mellem Island og Jan Mayen. Naar det sidstnævnte 

 Tversnit er oparbejdet indtil dets tidligere undersogte, nor- 

 ske Umhilhiliir/ii-Regiori. sejles til Tromsø, under Forud- 

 sætning af. at Tiden senere tillader, i August, flere Ar- 

 beider nordenfor Tromso. 



Naar Juli Maaned antages medgaaet til Jan Mayen- 

 Turen, vil den første Halvdel af August kunne anvendes 

 til Undersøgelse af Bankerne. Havbroen og endel af Ishavs- 

 dybet mellem Norge og Syd-Spidsbergen. Som Østgrændse 

 sættes Linien Nordkap. Bjorneøen. Sydkap. 



Den sidste Halvdel af August vil tiltrænges til Til- 

 bagerejsen til Bergen og Desarmering. 



Her course west will at first coincide with a line ex- 

 tending from Ando to .lan Mayen, and thence to the Arctic 

 Ocean, the basin and slopes of which the Expedition has 

 to investigate. From the nortb-eastern extremity of Jan 

 Mayen will be tåken a tew short series of soundings in a 

 north-easterly. a northerly. and a north-westerly direction : 

 for off this point. which is supposed to form the north- 

 eastern promontory of the valcanic region of Iceland. the 

 bottom would appear to sink precipitately in those direc- 

 tions. 



( )n the probable assumption tbat Jan Mayen is not 

 inaccessible from ice. the Scientific Staff will land on the 

 island. and prosecute exploratory work in divers hranches 

 — ■ geographical. geological. hydrographical. zoological. bo- 

 tanical, &c. 



The pbysical, and biological conditions of the sea off 

 the western and southern shores of Jan Mayen, should if 

 possible be investigated. there being some reason to infer 

 that a submarine ridge connects that island with Iceland. 



To investigate the conditions where the warm surface- 

 current from the Atlantic meets the glacial Polar flo w in 

 the Greenland sea. the Expedition will stand north-west of 

 Jan Mayen when making for the Greenland ice-barrier. 

 After exploring part of the Greenland ice-barrier. the Ex- 

 pedition will proceed to a point about midway between 

 Iceland and Jan Mayen, and from thence investigate the 

 bed of the Arctic Ocean in the direction of Rånen. The 

 existence or non-existence of a submarine' ridge connect- 

 ing together -lan Mayen and Iceland will tben be defin- 

 itivelv settled. When the last-mentioned section of the 

 Arctic basin has been explored throughout. irrespective of 

 its Norwegian Umbéllularia region, investigated previously. 

 the Expedition will return to Tromso. provided there be 

 time for subsequent exploratory work (in August) north of 

 that port. 



It. as expected. the 'Expedition get back from Jan 

 Mayen by the end of July. the first half of August can be 

 devoted to further investigation of the banks, and part of 

 the Arctic basin between Norway aud the southern ex- 

 tremity of Spitzbergeu. A line tangent to the North Cape. 

 Beeren Eiland. and South Cape marks the eastern limit of 

 the tract to be explored. 



The latter half of August. will be needed for the pas- 

 sage home to Bergen, and for discharging the vessel. 



De videnskabelige Arbejder udfores væsentlig paa 

 samme Maade som i 1876. 



Ved de zoologiske Arbejder lægges ved Siden af 

 Fangst med Skrabe. Trawl og Svabere, særlig Vægt paa 

 Anvendelse af Drivgarn og Net i intermediære Dybder, 

 samt Fiskeri paa Bankerne. Paa Jan Mayen antages 

 Fuglefangst at burde være Gjenstand af Betydning og ved 

 Grønlandsisen muligens Fangst af Sæl og Isbjørn m. m.

Tbe scientific work of the Expedition to be carried 

 out in all essential particulars as in 1876. 



With regard to tbe zoological work. especial stress 

 is laid on the use of the surface-net. and of the drag-net 

 in intermediate depths. apart from that of the dredge. 

 trawl. and swabs, .as also on fisking when exploring the 

 banks. During the stav at Jan Mayen, some time should. 

 it is thought. be devoted to collecting ornithological spec-
