anthropogenic effluents. At Hurghada it was varied between 2.48% in marina and 8.78% in the fishing port, while
at Safaga varied between 1.91% in grains wharf and 10.09% at coal wharf. On the other hand, the old port of
Qusier recorded insignificant variation in TOM percentages which ranged from 2.79 to 3.73%. The recorded
variation in the total organic matter (TOM) in bottom sediments of the studied ports at Hurghada and Safaga is
usually related to the local hydrodynamics, algal and seagrass flourishing, the terrigenous and domestic
wastewater. Mansour et al. (2013) attributed the recorded TOM at Hurghada to the seagrass patches and the algal
bottom faces.
