towed at different levels at an uncompleted 24-hour station (393, see Station List). The 

 catches are not strictly comparable to the routine samples, but they strongly suggest 

 that off the north-east coast in May there was far less plankton than in January.

In the 1 930-1 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).
