EEPOET ON THE HYDEOGEAPHIC, PLANK- 

 TONIC AND OTHEE PEEIODIC CEUISES OF 

 THE "JAMES FLETCHEE" IN 1912. 



By W. Eiddell, M.A. 



The positions of the various Stations are shown in 

 the chart on page 2-34. Surface temperatures and water- 

 samples were taken at all Stations. 



At Stations 5, 6, and 7, water-samples and tempera- 

 tures were also taken, except where the contrary is stated, 

 at 30 metres and near the bottom. 



For the deep samples, the Nansen-Pettersson 

 insulated water-bottle was used in the earlier cruises. 

 Since September the Ekman reversing water-bottle has 

 been used. 



The plankton samples were taken with the Nansen 

 vertical net of No. 20 silk and with surface horizontal 

 tow-nets.
