Surface sediment samples were collected from sixteen different
locations along the Suez Gulf, Aqaba Gulf and the Egyptian
Red Sea coast during 2011 (Fig. 1). Surface sediments were
collected with Van Veen grab from the upper 5 cm. After collection,
samples were putted in pre-cleaned wide-mouth glass
bottles, stored at 20 C until analysis. The samples were analyzed
according UNEP techniques (UNEP/IOC/IAEA, 1991,
1992). The samples were air dried at room temperature, then
kept in a clean stopped polyethylene bottle to be ready for
grain size, total organic carbon (%TOC), and total organic
matter. The water content for sample was estimated by drying
exact weight of each sediment sample in the oven at 105 C to a
constant weight.
