Evidence of fresh oil from the BP/Deepwater Horizon Mississippi Canyon-252 (MC-252) well was found in the northern Gulf of Mexico up to 1 year and 10 months after it was capped on 15 July 2010. Offshore and coastal samples collected after capping displayed ratios of biomarkers matching those of MC-252 crude oil. Pre- and post-capping samples were compared. Little weathering had occurred, based on the abundance of low-molecular-weight (LMW) n-alkanes and polycyclic aromatic hydrocarbons (PAHs) in the post-capping samples. The occurrence of fresh oil in offshore waters and coastal areas suggest that the MC-252 well continued to leak hydrocarbons into the Gulf of Mexico at least until 22 May 2012, the end of this study period.
2010年7月15日英国石油公司(BP)“深水地平线”号密西西比峡谷252号(MC - 252)油井被封堵后,在墨西哥湾北部发现了来自该油井的新鲜原油,时间长达1年零10个月。封堵后采集的近海和沿海样本显示,生物标志物的比例与MC - 252原油相匹配。对封堵前后的样本进行了比较。根据封堵后样本中低分子量(LMW)正构烷烃和多环芳烃(PAH)的含量,几乎没有发生风化现象。近海海域和沿海地区出现新鲜原油表明,MC - 252油井至少持续向墨西哥湾泄漏碳氢化合物直至2012年5月22日,即本研究期结束。
