Constant existence of CH4 and methanogens in marine surface sediment imply potential methanogenesis in the presence of sulfate, while the magnitude of this cryptic CH4 production and the underlying mechanisms remain elusive. This is the starting point of my PhD project in the center.

The project aims to identify sources and quantify controls on methane production in marine surface sediments using both isotope and molecular biological techniques. The project will challenge current knowledge on how and where methane is produced in marine sediments. The results of this project will provide new insights into (a) the role of methane cycling in the turnover of organic matter in marine surface sediments, (b) controls on microbial methane cycling in marine surface sediments, and (c) the role of the seafloor as a global source of methane to the hydrosphere and atmosphere.
