摘要
甲烷(CH4)是一种重要的温室气体,工业革命以来,大气中CH4浓度已增长了2~3倍。北冰洋沿岸冻土地带和冰川地质区域下埋藏了巨量的CH4储量,在全球气候变化背景下,北冰洋快速增长的CH4释放通量和可能产生的后果引起了人们的广泛关注。综述了北冰洋CH4的研究现状,着重介绍了北冰洋CH4的分布特征、通量及其生物地球化学行为,最后探讨了该研究领域中存在的问题。
Methane( CH4) is an important greenhouse gas, CH4concentrations in atmosphere hve increased by 2-3 times since the Industrial Revolution. Considering the huge CH4 storage in the Arctic Ocean, the fast increasing flux and their consequences are attracting more and more attention. This paper summarized the advances in the study of CH4 in the Arctic Ocean, especially the distribution pattern and air-sea flux and its biogeochemical cycle in the Arctic Ocean. It also presented the research prospect for the future.
