Interactive comment on “ A model of the methane cycle , permafrost , and hydrology of the Siberian continental margin

چکیده
This paper presents a 2-D model of the methane cycle for the Siberian continental margin, including permafrost, hydrates and transient fluxes. Model is described in a differential way compared to the initial version used for another region (section 2). Results are presented (section 3) concerning initial spinup, impact of freshwater hydrology, glacial cycles and upcoming global warming. A discussion on the model limitations and implications of climate change on Siberian methane fluxes close the paper (section 4).

Interactive comment on “ A model of the methane cycle , permafrost , and hydrology of the Siberian continental margin ” by D . Archer
The author has chosen a very important topic which definitely needs further thorough study. In this manuscript, a simple 2-D model of the passive continental margin is applied to simulate processes in the tectonically active environment of the Russian Arctic Shelves. The developed model considers a single latitudinal cross-section, employs greatly simplified physics assumptions and is eventuall...
متن کاملA model of the methane cycle, permafrost, and hydrology of the Siberian continental margin
A two-dimensional model of a sediment column, with Darcy fluid flow, biological and thermal methane production, and permafrost and methane hydrate formation, is subjected to glacial–interglacial cycles in sea level, alternately exposing the continental shelf to the cold atmosphere during glacial times and immersing it in the ocean in interglacial times. The glacial cycles are followed by a “lon...

The present study reports metagenomic shotgun sequencing of microbial communities of two ancient permafrost horizons of the Russian Arctic. Results demonstrate a significant difference in microbial community structure of the analyzed samples in general and microorganisms of the methane cycle in particular.
متن کاملMethanogenic community composition and anaerobic carbon turnover in submarine permafrost sediments of the Siberian Laptev Sea.
The Siberian Laptev Sea shelf contains submarine permafrost, which was formed by flooding of terrestrial permafrost with ocean water during the Holocene sea level rise. This flooding resulted in a warming of the permafrost to temperatures close below 0 degrees C. The impact of these environmental changes on methanogenic communities and carbon dynamics in the permafrost was studied in a submarin...
