During the months of May to August 1910 the Norwegian research steamer 

 Sars" accomplished a cruise in the North Atlantic under the superintendence of Si 

 Murray, K. C. B., and Dr. J o h a n H j o r t, director of the administration of Nc 

 fisheries. Dr. Hjort has published a short review of some of the main result 

 cruise,') in which he says: 



We first experimented with the trawl, and undertook hydrographical inve; 

 to the west of Ireland, over the slope of the coast banks. Our course was then set j 

 Bay of Biscay, where we made a number of investigations, towards the north-we 

 of Spain. From there we followed the Spanish and Portuguese coasts down tq 

 where we obtained a series of current measurements in the strait. Cadiz Ba 

 examined and careful hydrographical observations of the currents were madeo 

 'sections of these interesting waters, while series of trawlings were at the same ti 

 taken from the coast down to profound depths. /\ 



We then steamed in the direction of the Canary islands, and examined tl - 

 banks from the coast to the ocean floor, and subsequently crossing a large section of the ^^'^

of this seiction, comprising 40 stations, we made constant hydrographical investig£| 

 employed many different kinds of instruments for collecting plankton organism^ <^

 Wyville Thomson ridge— to study the transition from the Atlantic to the No

In the case of hydrographical material we collected 2400 water-sam
