Fig. 9. The average concentration of dissolved inorganic phosphate, chlorophyll a in the particulate
matter and zooplankton in the upper 100 m at stations off the SE Arabian coast, from observations
made by RRS "Discovery". On the left of the diagram (A) the observations from the summer of
1963 are plotted on sections normal to the coast, section I at Ras Fartak and II, III, IV and V
progressively further east along the coast. Section III is off the Kuria Muria Islands. On the
right-hand side (B) the observations on section III are reproduced together with repeat observations
of the same stations made in March and May, 1964
