Gas hydrates in marine sediments have been known for many years but recently hydrates
were found in the sediments of Lake Baikal, the largest freshwater basin in the world. Marine …

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 …

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

Lake Pavin is a meromictic crater lake located in the French Massif Central area. In this
ecosystem, most methane (CH4) produced in high quantity in the anoxic bottom layers, and …

The microbial community of a deep (to 234 m below the sea floor) sediment gas hydrate
deposit (Cascadia Margin Ocean Drilling Program Site 889/890, Leg 146) was analysed for …

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 hydrates deposited in subseafloor sediments are considered to primarily consist of
biogenic methane. However, little evidence for the occurrence of living methanogens in …

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 …

Phylogenetic analysis of the bacterial communities in Lake Baikal bottom sediments in the
region of subsurface methane hydrate discharge has been carried out using data on 16S …

Molecular and stable isotope compositions of hydrate-bound gases collected from 59
hydrate-bearing sites between 2005 to 2019 in the southern and central sub-basins of Lake …
