DISCOVERY REPORTS 



stations at B 6, B 7 and B 8, and a full routine station at B 9. B 5 was repeated as a 

 full station down to 500 m. depth. Two series of consecutive net hauls were taken: one 

 of 23 hauls and one of 51 hauls. 



On February 6, the 'Discovery' sailed for the South Orkneys and the Bransfield 

 Straits taking full routine stations 160 and 161 to the west and south-west of South 

 Georgia; the remaining stations on her voyage farther south are not included in the 

 present report. The 'William Scoresby ' sailed for the Falkland Islands on February 17 

 taking a horizontal routine station at 66 and full routine stations at 67, 68, 69 and 70 on 

 the way (see Fig. 14).

At the end of May the ' William Scoresby ' returned to South Georgia before running 

 a line of stations across the Southern Ocean to Cape Town ; here she repeated the five 

 stations on the C line of the survey to compare with conditions found on this line on 

 previous occasions in November, December and March of the previous year. 



It should be remembered that in planning the positions of the stations in all this early 

 work, we were without any knowledge of the hydrological conditions such as is outlined 

 in the previous section. The data on which this knowledge is based were collected at 

 the same time as the plankton, and only subsequently, after their analysis and corre- 

 lation, was this picture of the hydrological conditions round South Georgia obtained.
