Abstract A synoptic study of the phytoplankton and zooplankton distribution in the eastern Mediterranean Sea was carried out in the summer of 1965 during a cruise of R.V. “Pillsbury”. The phytoplankton maximum was normally found at 100 m, below the 1% level of surface light, with a frequent smaller peak at 40 m. In shallower waters, the main peak was at 80 m. The greatest number of phytophagous crustaceans was recorded at, or close to, the phytoplankton maximum. Depth relationships of phytoplankton and functionally phytoplanktonic species are discussed. Zooplankton was collected from depths down to 4,400 m, the deepest cast being in the Rhodes Deep. The most common species and genera of some selected groups of zooplankton were identified and their distribution considered in the light of some previous cruises in part of the area. The presence of Acantharia containing zooxanthellae with chlorophyll at, and below, 4,000 m was recorded for the first time. Potentially photosynthetic Ceratium vultur and C. carriense (Dinophyceae), both species in active division, were also found at these depths, as well as Halosphaera viridis (Prasinophyceae), which was recorded down to a depth of 1,000 m.
