PHYTOPLANKTON OF SOUTH GEORGIA

South Georgia area during the latter part of that summer lies in the fact that the currents 

 from the Weddell Sea appeared to be unusually slack, so that the greater part of the area 

 was occupied by old water of Bellingshausen Sea origin. It was only to the east of the 

 island, where the Weddell Sea influence was shown by higher sahnities and lower 

 temperatures at the surface, that moderately rich phytoplankton hauls were obtained on 



this survey.

In considering the work done in the South Georgia area as a whole, it has become very 

 evident that the different origin of the three main types of surface water, and the extent 

 to which mixing takes place between them, exerts a profound influence upon the nature
