Data_Sheet_1_The Impact of Methane on Microbial Communities at Marine Arctic Gas Hydrate Bearing Sediment.docx
Cold seeps are characterized by high biomass, which is supported by the microbial oxidation of the available methane by capable microorganisms. The carbon is subsequently transferred to higher trophic levels. South of Svalbard, five geological mounds shaped by the formation of methane gas hydrates,...

Cold seeps are characterized by high biomass, which is supported by the microbial oxidation of the available methane by capable microorganisms.

Methane gas seeping activity has been observed on four of them, and flares were primarily concentrated at their summits. At three of these mounds, and along a distance gradient from their summit to their outskirt, we investigated the eukaryotic and prokaryotic biodiversity linked to 16S and 18S rDNA.
