Abstract : A unique feature commonly referred to as a shoal called Shiab Al-Kabeer or Abu Tair sits almost in the middle of the Red Sea. The shoal is almost completely made up of live and dead corals with almost over 90 % of calcium carbonate input to the area. The shoal undergoes various degree of stress either by human activities or natural causes. The dynamics of the area is controlled by varying water currents generated either by wind or by tidal cycles. The shoal is inhabited by various fauna and flora exclusive to the Red Sea. Clear and uncontaminated water helps in keeping the sub-environment of the shoal healthy, although minor irreversible process might be a concern at large. Sediment input to the area mostly of carbonate origin largely contributed by the corals with subordinate aeolian quartz and terrigenous material from various sources. The veneer that is rich in biogenic material in the form of shells, forams and abundant coral debris are relatively coarser and darker in colour and poorly sorted with little fine sediment, and if present, are in minor amounts and calcareous in nature. This is related to weak currents where the environment is relatively stagnant, but coarse debris are contributed by human activities and fine sediment by further breaking down by parrotfish. The staining of the sediments in the Shiab Al-Kabeer is not as severe as compared to other areas but is found to be restricted in terms of the distribution pattern. Various remotely controlled technologies show different geomorphological features, whereas ground-truthing shows the activities that currently plays an important role in sediment movement especially in the sub-environments of the shoal. The sediment veneer shows that coarse sediment dominate the shoal mostly of biogenic origin. Since the current research is the only detailed work, a more comprehensive future strategy to understand the shoal and its inhabitants have been recommended that would not just help the clean environment
