| Abstract: |
| As an important part of global carbon cycle， seafloor cold seeps system is becoming a frontier in modern marine science and geological survey due to its extensive distribution， complicated mechanism， close relationship with natural gas hydrate and the importance of the related scientific issues. This paper reviews several focal science issues about carbon cycle in submarine cold seeps， including the role of authigenic carbonates as products of anaerobic oxidation of methane （AOM） in the carbon cycle， the contribution of deep carbon at continental slope， and the relationship between cold seeps and mineral resources. Furthermore， we also introduce some important means to detecting and monitoring cold seeping activities， including multibeam system， submerged platforms mounted with various sensors and mass spectrometers and several marine observatories aiming to long-time continuous observations of the cold seeps. In addition， we also discuss the development trend and key problems in this area along with our countermeasures， for peer learning and reference. |
