Red Sea is one of the world's major strategic shipping routes for crude oil transportation. Accidental spills of crude oil into the environmentally sensitive marine environments are known to impact the marine life. However, studies on direct assessment of oil spill on marine ecosystem, in particular on the primary productivity and bio-optical parameters in the Red Sea waters were poorly constrained owing to lack of sustained observations. Thus, in this study, an attempt has been made to use high spatial and temporal resolution of Moderate Resolution Imaging Spectroradiometer (MODIS) observations to monitor the oil spill explosion occurred on October 11, 2019, and its impact on the chlorophyll -a (Chl-a) concentrations. We noticed a significant increase in concentrations of Chl-a on the following day of oil spill. These changes are accounted for and are influenced by hydrocarbons along the track of oil spill. Our findings suggest that both wind speed and high Ekman pumping velocity support the upwelling of nutrient-rich water from subsurface, which facilitated the growth of phytoplankton and thus the high Chl-a in the oil spill areas.

红海是全球主要的原油运输战略运输路线之一。众所周知，原油意外泄漏到对环境敏感的海洋环境中会影响海洋生物。但是，由于缺乏持续的观察，对海洋生态系统溢油的直接评估，特别是对红海水域的初级生产力和生物光学参数的直接评估研究受到的制约很有限。因此，在本研究中，已尝试使用中分辨率成像光谱仪（MODIS）的高时空分辨率来监测发生在2019年10月11日的溢油爆炸及其对叶绿素-a（Chl -a）浓度。我们注意到漏油的第二天，Chl-a的浓度显着增加。这些变化是沿漏油径迹的碳氢化合物造成的并受其影响。我们的发现表明，风速和高Ekman抽水速度都支持地下富含营养的水的上升，这促进了浮游植物的生长，从而促进了溢油区的Chl-a升高。
