This is a study of methane oxidation in marine sediments and in the water column. The PI will focus on samples from the Black Sea Expedition, samples from a forthcoming cruise to Australian coastal waters, and on chemostat experiments in the laboratory using sediments from Scan Bay,, Alaska. Stable carbon and hydrogen isotopes will be measured to provide an estimate of the presence and the extent of anaerobic methane oxidation. The chemostat experiments will lead to an understanding of the substrates and the mechanisms involved in this oxidation process.

这是一项关于海洋沉积物和水柱中甲烷氧化的研究。该项目将重点关注黑海探险队的样本，即将前往澳大利亚沿海水域的巡航样本，以及使用阿拉斯加斯堪湾沉积物在实验室进行的化学调节实验。将测量稳定的碳和氢同位素，以估计厌氧甲烷氧化的存在和程度。化学调节实验将导致了解底物和机制参与这一氧化过程。
