PREFACE 



In the present work. I liavc collected tiic results of the hydro graphical and biological investigations made by ine in some ul' 

 the liords in the nortii of Norway, in the winter of 1899 and 1900, when at the cost of the Norwegian government and the Bergen 

 Museum I maile investigations in the lishing waters of Lofoten. For this purpose, I hired a little steamer „Gunnar Berg" from Januaiy 

 to the beginning of May, 1899. During these months, observations were made in the Vest Fiord and in the sea beyond Lofoten, 

 Vesteraalen, Senjen and Finmarken. Several fiords were also visited, as for instance, the Kirk, the 0gs, the Kanstad, the Sag-, the 

 'i\s and the Ofoten Fiords, Skjomen, Rombaken, Malangen, Lyngen, Kvænangen (including the Jøkel Fiord), the Porsanger Fiord etc. 



In the winter of 1900, S/S „ Asbjørn Selsbane" was hired for one month, so that investigations might be made in the fishinir 

 hanlcs wliich would fninish material with which to compare the results obtained the previous year. We weix' also aliic to visit tiic 

 IMorsdai, Salten. Skjerstad and Folden Fiords. Of these, the Skjerstad Fiord proved to he especially interesting. 



The following apparatus were used: — 



1. Dr. Pettekson's water bottle and meter wheel, 



2. A crab with 1000 meters af bronze-line. 



3. German nets for plankton gatherings, 



4. Dr. Petersen's closing net, 



5. Dredges and a small ti-aAvl for zoological gatherings, 

 (i. Lines and ropes. 



The dredges and trawl were drawn up liy the steam winch, but we took in the watei' bottle and the plankton nets witii 

 one worked by hand. 



I had a veiy capable assistant, Mr. Niels Haac;ensen', both winters, he rendered very gi'eat service m many ways. For 

 tile sake of uniformity, I took all the temperatures personally. Li determining the zoological material, I have had many helpers, Nor- 

 wegians and foreigners. But, unless otherwise stated, I am personally responsible for the arrangement of the species, and for the remarks, 

 wliich, in some cases, are added. I am especially indebted to my friend, Mr. E. Jpkgensen, for his exceedingly careful treatment of 

 the Protistplankton and the Diatoms in the Bottom samples. 



To the following naturalists, I also wish to tender my hearty thanks for their kind assistance, viz: —
