(The bearings given are magnetic.) 



At each station the following programme of work is carried out : — 



1. Hydrogo^aphic and Meteorological. — The temperature of the 

 water at the surface is taken, and also, by means of the Pettersson- 

 Nansen water-bottle with thermometers graduated to yV° centigrade, 

 the temperatures at 5, 10, 15, 20, 30, 40, 50, 75, 100, 125 metres, and 

 at the bottom. 



Samples of water are procured at each of the above depths, and 

 from these samples the salinity is subsequently determined in the 

 laboratory by Volhard's titration method. 



Observations of the temperature of the surface water are taken 

 every two hours when running between the stations, and meteorological 

 observations, including readings of the barometer and of the wet and 

 dry bulb thermometer, are made at similar intervals. 



2. Plankton. — Samples are taken with the following nets at each 

 station : — 



(a) A vertical haul with a small Hensen net, the silk of which has 

 150 meshes to the inch. 



{h) Hauls with the Garstang closing net, fitted with silk having 

 100 meshes to the inch, at 10 metres, mid- water, and bottom. 



(c) Surface gatherings with four ordinary tow-nets having silk 26, 

 50, 100, and 150 meshes per inch respectively. 



The eight samples from each station are subsequently examined
