ABSTRACT Our team completed a broad multidisciplinary survey in 2003 characterizing several thousand transects along 850 km of oil-impacted shoreline to determine the impacts of the 1991 oil spill on the Saudi Arabian Gulf from the western end of Abu Ali Island to the Kuwait border. Salt marshes and tidal flats there form a very significant portion of the oil-impacted coastline. These habitats were heavily oiled in 1991 and significant loss of biological communities was reported then. Although a large scale response effort followed the spill, the size of the spill overwhelmed it. The overwhelming majority of the spill site is remote and will likely receive little or no cleanup and/or restoration effort. After completing the survey, we conducted an ecological survey at two selected salt marsh transects using line-intercept and quadrat counts counting macrovegetation and intertidal macroepibenthos within one impacted (recovering) and one unoiled (comparison) transect. The objective of our paper is to present useful highlights regarding the nature of the recovery of intertidal macroepibenthos and the vegetation associated with salt marshes. A continuing impact to key species and their assemblages is documented and discussed. We conclude that while recovery has progressed from initial reports of significant damages in 1991–1993 the overall recovery of the salt marshes is far from complete. Some areas of considerable size and importance show little or no sign of recovery. In summary, the oil spill of 1991 was arguably the largest coastal spill in history. Long-term effects are widespread, appear to be profoundly large-scale, and in some cases salt marshes show little sign of natural recovery.

Abstract This research work has been done mainly to determine the natural radioactivity levels and the anthropogenic radionuclides (if detected) in seawater and beach sand in three selected regions; Khafji, Safaniyah and Menifah along the Saudi Arabian Gulf coast, for their closeness to the Iranian Bushehr nuclear plant and the presence of nearby non-nuclear activities (oil fields). The activity concentrations of the analyzed natural radioisotopes 226Ra, 228Ra and 40K in beach sand and seawater samples were all lower than the corresponding world average values. The anthropogenic radionuclides 137Cs and 241Am were not detected in all samples by the high efficiency germanium detector. Radiological hazards were quantified by the estimation of the absorbed dose rate, the annual effective dose and the external hazard index. On the basis of the current findings, we may conclude that the radioactivity levels in these marine Gulf Coastal regions don’t pose any radiological hazards to the public.

Sabkha is an inferior and indigenous type of soil which forms widely in the Arabian Gulf and in many parts of Saudi Arabia, especially in the coastal areas. Several studies over the last 25 years have been conducted to develop a better understanding and characterization of Sabkha soil and to improve its strength and durability. Different studies from different perspectives, different geographical locations, and particular types were discussed with specific treatment for its improvement. The main purpose of this study is to conclude Saudi Arabian Sabkha Soil characteristics, its associated problems, and to recapitulate the current technologies and practices for the improvement of it. The relative advantages and some of the drawbacks of currently available techniques have also been discussed. Scope and future development regarding this field have also been summarized. Preloading technique was found to be effective for stabilization and consolidation of Sabkha soil over longer period of time. Another study revealed characterizing Saudi Arabian Sabkha soil using seismic refraction technique. Other comparative research was studied which focused on the improvement of Sabkha soil for road construction using geotextile and cement additives. The results suggest that both of the techniques have similar effect on the improvement of subgrade but the geotextile application is more economical as compared to others. Geotextile (grade A-400) with greater strength and thickness exhibits higher load carrying capability which leads to less deformation settlement on the subgrade.
