摘要
甲烷、二氧化碳的地质和生物地球化学循环对海洋环境和全球气候变化有着重要影响,其在深海环境中通常以气泡或流体的形式向四周扩散,甲烷还是探测海底天然气水合物资源的重要指标之一。目前,国内外研究团队提出了各种背景下原位探测海洋溶解甲烷、二氧化碳的新技术、新方法,以促进对海洋碳循环的研究。简述了基于电化学技术、光学技术、质谱技术和生物传感技术等对海洋溶解甲烷、二氧化碳进行原位探测的最新进展,系统介绍了各传感器的工作原理和性能,分析其应用价值和前景,并在此基础上对未来的研究方向提出一些建议。
The geological and biogeochemical cycle of methane and carbon dioxide in the ocean has an important impact on the marine environment and global climate change. In many deep-sea environments, methane and carbon dioxide usually diffuse in the form of bubbles or fluids, Methane is also one of the important indicators to detect the resources of natural gas hydrates. At present, in order to promote the study of marine carbon cycle and flux, research groups at home and abroad have proposed new technologies and methods for in-situ detection of dissolved methane and carbon dioxide in the ocean under various backgrounds. In this paper, the latest progress of in situ detection of dissolved methane and carbon dioxide in the ocean based on electrochemical, optical, mass spectrometry and biosensor technologies is reviewed, the working principle and performance of each sensor are introduced systematically, the application value and prospect of it are analyzed, and some suggestions for future research are put forward.
