It is about 2.32 km2, wh more than 7 tons of oilFigure 7. In the area 2 we identified a big oil spill and similar to the spill identified in the area 1. It is very clear this is a serious oil spill that spreaded over 14 km 2 , and most propabley it was released on July 25 th , seeing the rapid progress and development of the spill through the follwing days. From the dark color of the spill on 25 th and 26 th , it is like a fresh oil spill, and within few days 31, the spill started to disappear in the wa damage to the marine life. we can expect th big oil spill would go from July 2425th to means about days we didnt notify any anno incident from any media in the Gulf, we ha far from the coast of Abu DHabi, it is about from Sir Bu Nair Island, it is close by abo serious distance Figure 8 The movement of the this spill and its direction are controled by local climate condition in particularly the wind and current, but we observed, it didnt travel much and it developped almost in the same region Figure 9.Finding such as thi considering all its environmental and necessitate a continous monitoring o environment. : A serious oil spill covering an area more than 14 km2 : Development of the oil spill of July th Figure 10: co successive da spills are occ rudes and light refined ickly spread into very films when spilled nce aerial-obervation. zing the successive days on the area r one, we see how fast persion of the oil spill, is means almost every ere are several of oil lease in the water, and disappear deep in the lf marine water, marine life.

We conclude that remote sensing of SAR imagery is very crucial fo monitoring of oil spill. The importa large coverage, the high frequency demonstated a daily coverage and with the help of more than one s proved its capability to detect clearl helped us to identify even the ver and the high frequency of data aq with daily coverage, helped us addition it is now very easy to aqui spill report in less than one hour, a AIS, which give information abou can claim a near real time oil spill m The big number of oil spills, whe spills events, is a clear evidence o we linked this as well to the intens particularly for the supply and production platforms. This indicat oil spill are the illegal actions, in pa of ballast water and the bunkering a We notified the rapid disappear o only few hours, but the bigger on days, all depend on the size and th be crude oil or ligh diesel. Finally, and as we suggested recommend to the national autho near-real time oil spill monitori satellite imagery, with the support navigation radars.
