Distribution of young Euphausia superba, Cape Town, Bouvet, South Georgia (i-m. net hauls), October-November 1930. young have been obtained, usually in great abundance. When making our way through the pack, either in the main body of it or when crossing the narrow tongues, krill was almost always to be seen and often it occurred in great quantity. The young stranded themselves in numbers on floes that we momentarily submerged in our passage, while the adults, with greater activity, often jumped clear of the water and landed kicking on ice some 10 or 12 inches above the surface. The quantity of krill to be found in and near the pack at this season is amazing and the reason why whales haunt the ice- edge is ; South Georgia survey, November 1930 (Sts. 474-525). Fig. 70. After the completion of the Bouvet-South Georgia stations a plankton survey round South Georgia was commenced. At the beginning of the survey, as stated by Mackintosh (1934, p. 127), the pack- ice was close up to the island, but at the end of November when the survey was completed the ice had receded some way to the south-east. There can be no doubt that the abundance in which young krill was found in the vicinity of South Georgia during this survey was due to the proximity of the pack to the island, and it is likely that earlier in this season the ice-edge extended north and west to the positions shown on the map where krill was especially abundant. It is likely too that the surface currents {vide Deacon, 1933, p. 183, fig. 5) would tend to transport the krill northwards and east- wards in the tongue of water extending along the north-east coast of South Georgia. South Shetland survey, December 1930 (Sts. 537-555)- Fig. 71. In this survey the distribution of the young krill was much the same as that of the eggs described on p. 109. The greatest concentration was at St. 537, th
