Methane is the most abundant hydrocarbon in the atmosphere, and it is an important
greenhouse gas, which has so far contributed an estimated 20% of postindustrial global …

Measurements of dissolved methane in the ocean have been available for only about 50
years. Methane measurements in sediments, where concentrations are millimolar, were first …

Alkanes are saturated apolar hydrocarbons that range from their simplest form, methane, to
high-molecular-weight compounds. Although alkanes were once considered biologically …

The anaerobic oxidation of methane (AOM) is an important sink of methane that plays a
significant role in global warming. AOM was first found to be coupled with sulfate reduction …

In marine anaerobic environments, methane is oxidized where sulfate-rich seawater meets
biogenic or thermogenic methane. In those niches, a few phylogenetically distinct microbial …

Lakes are a natural source of methane to the atmosphere and contribute significantly to total
emissions compared to the oceans. Controls on methane emissions from lake surfaces …

Methane has long been known to be used as a carbon and energy source by some aerobic
alpha‐and delta‐proteobacteria. In these organisms the metabolism of methane starts with …

The stratified water column of the Black Sea is partitioned into oxic, suboxic, and euxinic
zones, each characterized by different biogeochemical processes and by distinct microbial …

Inputs of CH4 from sediments, including methane seeps on the continental margin and
methane‐rich mud volcanoes on the abyssal plain, make the Black Sea the world's largest …

Glycerol dialkyl glycerol tetraether (GDGT) compositions of suspended particulate matter in
the water columns of two anoxic marine settings, the Black Sea and Cariaco Basin, were …
