It was well known that on April 20,2010,the Deepwater Horizon oil drilling rig exploded to be fired with the largest release oil(~4.9 million barrels)at significant depth(~1500 m)into the ocean,resulting in 11 crew member fatalities.The disaster caused enormous environmental and economic damage,but also brought enormous variables to the oil development of United States even all over the word.In this paper,we reviewed that the science and engineering and various technological methods to evaluate the total amount of the spilled gas and oil and the flow rate at the surface and deep sea,and the corresponding models setting up for further study of the oil transfer trend.In order to prevent further contamination of oil spill on the coastline,6.6million liters of dispersants were sprayed to the surface and wellhead during the accident.These dispersants could stimulate oil dissolved in seawater,but also had some impact on the marine ecosystem.Vegetation and marine organisms are also subjected to different degrees impact such as marsh vegetation,oysters,coral community,fish,migratory shorebirds even the distribution of macrofaunal biomass in the deep-sea in the Gulf of Mexico.The damage of oil spill was associated with the activity of different toxic compounds,for example,polycyclic aromatic hydrocarbons were particularly dangerous on biological organisms.The oil spill provides a unique opportunity to examine changes in hydrocarbon-degrading bacterial community structures during oil movement and degradation,as this oil spill occurred across an enormous spatial gradient with drastically different environmental conditions.Although researchers in related fields have done a lot of research and achieved many achievements,the transport mechanisms of the dispersants treated oil pollution and the relevance of the biological markers associate with the biosurfactants produced by the hydrocarbon-degrading bacterial community during the degradation progress requires further in-depth discussion.
