. Fig. 27. Distribution of plankton quantities around South Georgia, 1928-9, Sts. WS 417-26. In the 1930-1 survey (November, Fig. 29), a very rich plankton was again found on the north side of the island, and a slightly less dense population to the south. The line repeated in March in the same season (WS 565-75) showed a considerable reduction in the plankton on the north side of the island (Fig. 30).
