Abstract
The peculiar environmental of Sharm El-sheikh area is threatened by different sources of pollution.The oil spill of 1999 in Sharm El-Maya bay represented an example of one of these threats .The present study aimed to determine the extent of the pollution, its spatial variation,and its source.Samples of the headland and seabed sediments and the seawater were collected and analyzed for petroleum hydrocarbons using conventional gravimetric techniques.An integrated geophysical survey was carried out using magnetic,gravity, and ground penetrating radar(GPR) techniques to investigate possible sources of pollution and their distribution in the headland area.The study showed that the average concentration of total hydrocarbons was 661.7+ or – 383.16 ug/g in the headland, 170+or -128.59 ug/g in the seabed,and 37.99+or -17.45 mg/l in the seawater.Spatial and temporal variations in total hydrocarbons were suggestive of a land-based source of pollution related to damaged,underground fuel-storage tanks and pipelines.
