OSCAR SUND 



[REP. OF THE "MICHAEL SARS" NORTH 



Record 



of horizontal hauls intended to provide samples of zooplankton during the "Michael Sars" expedition 1910. 



The appliances used were: — conical silknets with 

 mesh in end-part of 0.5 mm. (Vi square millimeter) and 

 with a diameter at the opening of Va, 3 U or 1 meter 

 (designated in the tables as Va sn, % sn, 1 sn); conical 

 nets made of shrimp-trawl net, diameter at the opening 

 3 m. ("3 In"); and young-fish trawls og C. G. Joh. Peter- 

 sen's model ("y"). In the first table (I) each haul is 

 represented by a figure showing length of wire between 

 the appliance in question and the ship. The actual depth 

 is, of course unknown, but may roughly be guessed as 

 about two thirds of the length of wire, in hauls near 

 the surface perhaps somewhat less. — The surface-hauls 



were alle made by means of a one-meter silk net. Table II 

 shows the duration of each haul in minutes. Table III 

 giwes a view af all the horizontal zooplankton hauls, 

 distributed over the different depths (i. e. wire out) and 

 over the four are as into which the regions travesed 

 during the voyage may conveniently be divided. NE 

 comprises station 1—12 and 87—116, NW stations 70— 86, 

 SE stations 13 — 59 and SW stations 60 — 69. Operations 

 began on the the 9th of april 1910, at st. 1 and ended 

 aug. 14 1910 at st. 116. 



The position of the stations may be gathered from 

 the three charts, pag. 35.
