Description 1981-1988
Phytoplankton community was investigated quantitatively
at three sectors along the Egyptian Mediterranean coast (Rosetta, Abu-Qir and Eastern Harbor) during winter, spring and summer
2008-2009.   Phytoplankton count reported wide temporal and
spatial variability between a minimum of 72 units/l and a maximum of 5.77x106
units/l. Chlorophyceae and Bacillariophyceae were the main components. More
than 207 phytoplankton species were identified, but a few only demonstrated
active contribution to total standing crop, such as the green algae Carteria
sp. and marine Chlorella vulgaris, the diatoms Asterionella
glacialis, Cylindrotheca closterium, Melosira granulata, Navicula
cryptocephala, Pseudo-Nitzschia palea, Pseudo-Nitzschia sigma,
Pseudo-Nitzschia delicatissima, Skeletonema costatum, and the
dinoflagellate  Gonyaulax spp..
Spring was characterized by the lowest plankton density along the whole area,
with a minimum of 317units/l off Rosetta Sector, and summer sustained the
highest phytoplankton count (2.075 x 106 units/l) also at Rosetta
Sector. The species diversity of phytoplankton community was quite high, being
the most diversified (117 species) off Rosetta. Shannon
index sustained values mostly less than 2, except off Rosetta during summer (2
-2.94 nats).
