深水地平线石油泄漏是前所未有的总负荷石油碳氢化合物意外释放到海洋生态系统。有争议的应用化学分散剂可能加速微生物消耗石油成分，特别是在温暖的墨西哥湾表面沃茨。我们采用三角洲（13）C作为石油衍生碳的示踪剂，以解决两个时期的同位素碳消耗在两个浮游生物的大小类。碳耗竭与北方海湾表层浮油的到来是一致的，这表明地下石油碳被纳入浮游生物食物网。
The Deepwater Horizon oil spill was unprecedented in total loading of petroleum hydrocarbons accidentally released to a marine ecosystem. Controversial application of chemical dispersants presumably accelerated microbial consumption of oil components, especially in warm Gulf of Mexico surface waters. We employed delta(13)C as a tracer of oil-derived carbon to resolve two periods of isotopic carbon depletion in two plankton size classes. Carbon depletion was coincident with the arrival of surface oil slicks in the far northern Gulf, and demonstrated that subsurface oil carbon was incorporated into the plankton food web.
