凯斯勒等人。 （报告，2011 年 1 月 21 日，第 312 页）报道称，2010 年深水地平线井喷释放的甲烷约占碳氢化合物排放总量的 40%，在 4 个月的时间里被墨西哥湾深水中的甲烷氧化细菌定量消耗。我们发现，将观测到的氧气异常与甲烷消耗明确联系起来的证据并不明确，而将这些观测结果扩展到水合物衍生的甲烷气候则迫使其为时过早。
Kessler et al. (Reports, 21 January 2011, p. 312) reported that methane released from the 2010 Deepwater Horizon blowout, approximately 40% of the total hydrocarbon discharge, was consumed quantitatively by methanotrophic bacteria in Gulf of Mexico deep waters over a 4-month period. We find the evidence explicitly linking observed oxygen anomalies to methane consumption ambiguous and extension of these observations to hydrate-derived methane climate forcing premature.
