  7. Abstract:
  8. Knowing the location and time of oil accidents and trying to track the pollution caused by these accidents is very important for the purpose of monitoring and protecting the environment. The occurrence of large oil spills in the marine environment can have serious environmental, social and economic consequences. In this research, oil spills in the Persian Gulf were first identified using remote sensing method and Sentinel-1 satellite images. The images of this satellite were called for the processes needed to identify oil spills in Google Earth Engine space. After detecting the oil spills, it is necessary to determine the duplicate spills and remove these types of spills, as well as estimate the volume of the oil spills. Repetitive spills were determined based on the comparison between the volume and position of them over time with other detected spills based on the proposed algorithm of this research. The estimation of the volume of oil spills was based on their color. Then, by simultaneously solving the equations of diffusion, evaporation, emulsification, sedimentation, the routing of oil spills was addressed. Knowledge of the repeated pattern of pollution and its transfer to coastal areas is the aim of this research. Based on the results obtained from this research, the distribution of the detected oil spills is in good agreement with the shipping route in the Persian Gulf. Therefore, one of the causes of oil pollution can be leakage from the ship. In addition, the coasts of the UAE, Qatar and Kuwait are highly vulnerable with over 100 barrels per kilometer of coastline. Despite the lower vulnerability of Iran's coasts compared to other Persian Gulf coasts, parts of Iran's coasts, including the Mond protected area and Asalouye port in Bushehr province, have high relative vulnerability of 33 to 66 barrels of oil compared to other parts of Iran's coasts
