The water quality index WQI demonstrated that Sidikerir water was between medium and good. Trophic states, as well as factors affecting the water quality of study area, were evaluated. Total nitrogen and total phosphorous were fluctuated between 17.63–118.65 and 0.20–2.80 lM, respectively. Nutrient characteristics sustained the levels up to 1.68, 11.00, 8.82, 1.15 and 33.18 lM for reactive phosphates, reactive silicates, ammonium, nitrite and nitrate, respectively. They demonstrated a wide range of water temperature (17.14–26.31 ☌), narrow fluctuations in salinity (37.51–39.71), and well-oxygenated seawaters (4.16–8.00 mg O 2 /l), low amounts of oxidizable organic matter (1.92 mg O 2 /l) and the seawater was slightly alkaline (pH range 8.03–8.53). Suez Canal Authority produces tables of width and acceptable. Also of note is the maximum head room'air draft'limitation of 68 m (223.1 ft), resulting from the 70 metres (230 ft) height above water of the Suez Canal Bridge. Temporal, spatial fluctuations as well as statistical correlations between the analyzed variables were examined. The typical deadweight of a Suezmax ship is about 160,000 tons the typical beam (width) is about 48 m (157.5 ft). Subsurface and near bottom water samples were collected seasonally during 2012 at eight locations to measure physic-ochemical and nutrient salts characteristics as indicators of the water quality. This is an open access article under the CC BY-NC-ND license ().Ī hot spot region of the Mediterranean Sea located at Sidikerir west of Alexandria was chosen to evaluate the present status of its water quality due to the direct impacts of effect of the power station, petroleum pipe company (SUMED) and some tourist villages. on behalf of National Institute of Oceanography and Fisheries. This equation could be applied in the future to predict the total phytoplankton counts in the coastal waters of the northern part of the Red Sea, Egypt. The multiple regression model was: phytoplankton counts = 28,564 + 0.69 NO 3 + 0.284 NH 4 À 0.13 SiO 4 À 0.30 Salinity (M.R. The dissolved nitrate (0.07-2.27 lM), ammonium (1.82-8.80 lM), reactive silicate (0.41-5.22 lM) and water salinity (39.9-42.9&) were the most effective factors that controlled the seasonal fluctuations of phytoplankton during 2013. The physico-chemical properties of surface water exhibited seasonal and spatial variations. The species diversity fluctuated between 3.36 in the summer and 3.97 in autumn, with an annual average of 3.76. Autumn was the most productive season recording an average of 5916 unit/L, followed by spring (average of 5282 unit/L) and winter (average of 4329 unit/L), while summer showed the lowest counts (average of 3607 unit/L). Other algal classes like Cyanophyceae, Chlorophyceae, Euglenophy-ceae and Silicoflagellates sustained low counts, forming collectively about 9.0% of the total abundance of phytoplankton. A total of 145 species were recorded with clear dominance of Bacillariophyceae, which formed about 76.4% of the total phytoplankton counts with annual average of 3654 cell/L and Dinophyceae (14.63%) with annual average of 700 cell/L. Just before 3 p.m., as the tides rose in the jammed channel, the crews got their wish.Phytoplankton community structure and some environmental parameters in the coastal water of the north western part of the Red Sea were studied seasonally during 2013. The Nile Delta (Arabic:, Delta an-Nl or simply, ad-Delta) is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. local time on Monday, would help to dislodge the Ever Given. NASA satellite photograph of the Nile Delta (shown in false color) The Nile Delta at night as seen from the ISS in October 2010. Let’s nerd out over it together.įor days, salvage teams hoped that an unusually high tide, set to peak at around 11:42 a.m. While a small armada of tug boats, dredgers, and even a backhoe toiled day and night to free the 1,300-foot, 200,000-metric-ton vessel from the Suez Canal, the crews ultimately received the biggest helping hand from a surprising secret weapon: the moon. The canal, which was completed in August 1914, is one of the two most strategic artificial waterways in the world, the other being the Suez Canal. First, tide was applied only at Red Sea while.
