Dynamics of the Ocean Floor

Reactive fluid flow and gas hydrate modeling

Global POC accumulation rates (Wallmann et al., 2012).
Gas hydrate distribution at the Green Canyon 955 Site, Gulf of Mexico, derived from numerical modeling (Burwicz et al., 2017).

Project overview:

Numerical modeling of gas hydrates investigates the dynamics of gas hydrate formation and dissolution in marine sediments with a special focus on the multiphase reactive porous flow and the potential atmospheric/oceanic feedbacks. The scope of our current research is to understand and quantify the rates of gas hydrate crystallization from in-situ organic matter and its implications for the global hydrate budget, the mechanisms of upward free gas migration inside the Gas Hydrate Stability Zone (GHSZ), the role of bio-chemical processes associated with hydrate formation (POC degradation via sulfate reduction, methanogenesis, anaerobic oxidation of methane- AOM), and physical controls on gas hydrate distribution in marine anoxic sediments with various lithologies. Our numerical models are built upon a compilation of input data sets derived from various sources, including GEOMAR climate models (e.g. the Ocean General Circulation Model OGCM in ORCA_R025 configuration).
