| Species composition, abundance, and phytoplankton biomass in Lake Nasser were studied during the highest flood season in autumn 1999, and were supported by some physico-chemical environmental parameters. The nutrient salts levels were low to medium, with ranges of 0.96-9.92 g/L for nitrite, 20.14-72.14 g/L for ammonia, complete depletion -27.69 g/L for phosphate, and 5.83-9.00 g/L for silicate. A total of 71 taxa were identified, of which 46% were chlorophytes, 26% bacillariophytes and 22% cyanophytes. Phytoplankton abundance and biomass values were higher in the northern stations than in the southern, but were lower than previously reported, indicating approaching from oligomesotrophic status, with,respectively, means of 108.9 x 104 unit/L and 1.18... |

| Environmental Information and Monitoring Programme (EIMP) for the Egyptian coastal waters of Aqaba Gulf was established to initial monitoring and data base system by applying quality control assessments in order to evaluate, protect and sustainable use of coastal regions. Within the framework of this programme six bimonthly field campaigns were carried out annually during 1998 – 2004. A total of 11 coastal stations were selected to cover different locations of the Gulf. The surface distribution patterns of hydrographical parameters (water temperature, salinity, dissolved oxygen and pH) as well as chlorophyll-a, total suspended matter, transparency, nitrogen and phosphorus forms and reactive silicate were investigated. The obtained data of seven years work... |
