Opis:
During August 2000 and February 2001 two cruises were carried out along the Egyptian Mediterranean Coast on the Egyptian r/v ‘El-Yarmouk’. The samples collected were used to study the ecology and distribution of hydromedusae and siphonophores during summer and winter. The density of hydromedusae was high in the inshore waters during summer (av. 71 org × 100 m−3), decreasing to 28 organisms per 100 m3 in the oceanic waters; in winter they were more abundant in the middle and offshore zones. Ato tal of 9 hydromedusae species were recorded during the present study, 8 of them in summer. The most common of these were Aglaura hemistoma, Olindias singularis, Liriope tetraphylla and Geryonia proboscidalis. Only 4 species were recorded during winter, including Cunina octonaria, which was not recorded during the summer. The nine species recorded in the present study are circumtropical. The siphonophore density was high in summer. In winter, the average standing crop of siphonophores fell to about 30% of that recorded in summer. 11 siphonophore species were recorded, 10 of them in summer; Cucullus campanula and Eudoxoides spiralis were the most common. Only 6 species were recorded in winter. These 11 species are widely distributed – they have been recorded from the Atlantic, Indian and Pacific Oceans. Strong seasonality is thus a striking feature of Egyptian Mediterranean waters. Temperature is the most variable factor affecting the planktonic community, fluctuating between 26.5 and 27◦C in summer and between 16.3 and 17.5◦C in winter. The western part of the Egyptian coast, the area under study in this work, is poorly diversified in comparison with the eastern part.

Opis:
Using objectively analysed hydrographic data, currents have been calculated off the Egyptian Mediterranean coast at the surface and at 30, 50, 75, 100, 200 and 300 m depths for the four seasons. The surface circulation is dominated by an anticyclonic circulation off Salum Bay in winter, spring and summer. In nearshore areas, the current flows eastwards at the shallower levels but westwards at the deeper levels. Off the Nile Delta, the current is almost eastward with a higher velocity in summer and autumn, while in spring it is very weak. Off the area between Port Said and Rafah, there is a clear cyclonic circulation appearing in all seasons except winter. At 50 and 75 m depth, the velocity of the circulation is weak. At 100 m depth, the circulation that appeared between Matruh and Alamen in summer decreases in area and magnitude at the former depths. At 200 and 300 m in winter, the current velocity is quite low. In spring the current flows southwards off the area between Rafah and Port Said. In summer, the current off the area between Port Said and Rafah is quite strong and flows to the south. The situation in autumn is quite similar to that in summer, except in the eastern area, where the current is a westward one.
