چکیده
Step 1. We developed a kinetic model for organic matter degradation and methane formation within the gas hydrate stability zone and calibrated this model using pore water and solid phase data measured in marine sediments (MARQUARDT et al., 2010; WALLMANN et al., 2006). The major parameters that we used to calibrate the model are concentrations and depth profiles of dissolved sulfate and ammonium and depth

I decided 20 years ago to sign all my reviews irrespective of my thoughts on scientific content or on authorship. I mostly have tried being polite and constructive through about 600 reviews. The present manuscript tests my resolve, especially given recent commentary and discussions on the topic in the literature, as well as open correspondence with the senior author. The only means to stay true...

To obtain a good and realistic data base for determining our transfer function, we ran many realizations with our standard transport-reaction model covering the whole range of parameters found in nature. Analyzing all of these results, we have identified the most critical control variables and established an empirical relationship of those variables with respect to the gas hydrate content below...

The authors develop a parameterization to relate the local inventory of gas hydrate (in g/cmˆ2) to relevant input parameters (like water depth). These parameterizations are tuned to one-dimensional numerical models, which circumvents to the need to run numerical models with gridded data. Another approach is to use the numerical models to construct "look-up" tables for use with gridded data. The...

D. Burdige questions the validity of our kinetic model for microbial organic matter degradation and methane formation (WALLMANN et al., 2006) and urges us to look at the new paper on organic matter degradation kinetics recently published by the reviewer (BURDIGE, 2011). We would like to emphasize that our model has been calibrated more comprehensively by field observations at various ODP sites ...
