Assessment of heavy metals and nonessential content of some edible and soft tissues OceanDocs
Ahdy, H.H.H.; Abdallah, A.M.; Tayel, F.T..
The level concentrations of heavy metals (essential and nonessential) were measured in different marine biota including cephalopoda, bivalve, crustacean and fish. The results reveal that these organisms show more or less the same order of distribution for each of the metals studied. The average concentrations of heavy metals exhibited the following decreasing order: cephalopoda > bivalve > crustacean > fish. The levels of metals in all studied samples are still comparable to those in their corresponding in the Mediterranean Sea. K (98-181μg/g) and Ca (547-1472 μg/g) were present at the highest concentrations in all investigated samples. Octopus and Sepia do not follow the general pattern. The highest value of Metal Pollution Index (MPI) in...

Analysis of wave observations and wave transformations in abu-qir, egypt OceanDocs
Sharaf El-Din, S.H.; Abdallah, A.M.; Shereet, S.M..
Wave observations taken during 1986 in Abu-Qir Bay were statistically analyzed to calculate the wave parameters describing the sea state (significant wave height, wave period and predominant direction). On both sides of Rosetta promontory, the transformed wave parameters at break line (breaker height, breaker depth and crest angle) were calculated in terms of the predominant values of the significant wave height, period and direction using ACES software package. Breaker type and closure depth along Rosetta coast were also predicted. Generally, the wave effect in the bay was varying in intensity and direction in accordance with the prevailing wind. The average annual wave height and period are about 0.94 m and 6.5 s, respectively. Throughout the year, the...
