DISTRIBUTION OF PHYTOPLANKTON

moral is obvious: stations in a plankton survey should all be taken as nearly together in 

 time as possible. How difficult this ideal is to achieve is only realized by those who have 

 attempted it in seas where violent storms limit work to infrequent intervals of com- 

 paratively short duration. 



In March 1926, off the north-east coast of South Georgia, the phytoplankton was 

 remarkably poor both in numbers and species. The analysis of the three N 50 V nets 

 taken at this time is shown in Appendix I, Sts. 23, 31 and 41 C. Only five species are 

 recorded. The N 70 V nets which were used at sixteen stations yielded no larger catches.
