摘要
CH4 是大气中的重要微量气体 ,对全球变暖和大气化学有重要作用。海洋是大气甲烷的重要源和汇。开展海洋中溶存甲烷的研究 ,有助于了解海洋对大气甲烷和全球变化的贡献。综述了海洋中溶存甲烷的研究现状 ,着重介绍了海洋中溶存甲烷的分布特征、海气交换通量的估算及其生物地球化学循环 ,并探讨了该领域研究中存在的问题。
Methane,an important trace gas in the atmosphere,plays major roles in global warming and atmospheric chemistry The world's Ocean is both a source and a sink of atmospheric methane The studies of dissolved methane in the ocean are helpful to understand the contribution of the ocean to atmospheric methane and global warming This paper described the advances in the studies of dissolved methane in the seawater, especially its distribution in the ocean, the estimation of its air sea flux and its biogeochemical cycles in the ocean It also discussed the disadvantages in the present study
