Background Gas hydrate-bearing subseafloor sediments harbor a large number of
microorganisms. Within these sediments, organic matter and upward-migrating methane are …

Methane hydrates represent an enormous carbon and energy source in many low
temperature deep marine sediments. However, little information is available concerning the …

Marine gas hydrate and cold-seep systems, which maintain a large amount of methane in
the seabed, may critically impact the geochemical and ecological characteristics of the deep …

Little is known about the microbial distribution patterns in subseafloor sediments. This study
examines microbial diversity and activities in sediments of the Nankai Trough, where …

The biogeochemical processes, anaerobic oxidation of methane (AOM) and
methanogenesis, control methane emission and create distinct geochemical profiles with …

The degradation of organic carbon in subseafloor sediments on continental margins
contributes to the largest reservoir of methane on Earth. Sediments in the Andaman Sea are …

Gas hydrate systems are unique habitats for microorganisms in deep marine sediments, and
gas hydrate reservoirs can be divided into focused high-flux and distributed low-flux gas …

Assessing the impacts of methane released from hydrate-bearing environments on global
carbon cycling would require detailed insights into the distributions and capacities of …

Microbial diversity of sediments from the northern slope of the South China Sea was studied
by constructing bacterial and archaeal 16S rRNA gene clone libraries. Fourteen bacterial …

Gas hydrates harbour gigatons of natural gas, yet their microbiomes remain understudied.
We bioprospected 16S rRNA amplicons, metagenomes, and metaproteomes from methane …
