Dissolved methane gas in seawater not only has an important influence on global warming and changes in the marine environment, but also serves as a basis for discovering the occurrence zone of seepage-type gas hydrates. The new technology and new method for in situ monitoring of dissolved methane in seawater is to obtain seawater methane The main means of flux change process. The in situ methane sensor has the advantages of in-situ, real-time and quantitative observation at multiple time and space scales. It has wide application prospects in marine environmental change and global climate change research, as well as in the exploration and utilization of seabed resources. This paper introduces the detection principle and characteristics of dissolved methane sensor based on the membrane degassing, optical detection technology and biological sensing mechanism, discusses the research development prospect of in situ methane sensor, the research and development of new membrane materials, based on the optical detection technology and plasma resonance, Enhanced Raman scattering and other means of detection methods will be the future development of in situ methane sensor an important direction.
