DISCOVERY REPORTS 



This chart shows that around the coasts of Graham Land, the South Orkneys, the 

 South Shetlands, Adelaide Island, Alexander ist Land, etc., the summer plankton is very 

 thin. Away from this region in all directions it seems that the richness of the plankton 

 increases, and reaches a maximum in the South Georgia and South Sandwich region, 

 and to the west of Peter ist Island in the Bellingshausen Sea.

 organisms in each sample, shoaling species being omitted. Those in italics are day hauls and others are night 

 hauls. 



There can be no doubt of the contrast which normally exists between the South 

 Georgia and Graham Land areas, for these regions have been visited many times in a 

 succession of years. Nor can there be any doubt that the outer parts of the Antarctic 

 water between South Georgia and the Falkland Islands, harbour a quite rich plankton 

 during at least a large part of the summer. Cruises in the Bellingshausen and Weddell 

 Seas have been made on fewer occasions, but it is probable that there is always a rich 

 summer plankton in these regions.
