Hitching a ride: A gastropod-associated microbiome community at a Hydrate Ride methane seep and impacts on local biogeochemical cycling
Exploration of cold seeps from geological, chemical, and biological perspectives has grown exponentially in recent decades since the first discovery of cold seeps in the 1980s. Symbiotic relationships, often rooted in geochemistry of the environment, have proven to be ubiquitous at cold seeps. …

Diversity of meiofauna at deep-sea hydrothermal vents and cold seeps with particular reference to nematodes
Deep-sea hydrothermal vents and cold seeps are remarkable for their spectacular megaand<br/>macrofauna, many of which appear to have a high level of endemism to these chemosynthetic<br/>environments. It is not clear whether the patterns of biodiversity, faunal zonation<br/>and biogeography …

Stratigraphic and Geochemical Expression of Early Cretaceous Environmental Change in Arctic Svalbard
… This counters recent studies that suggest a methane-seep driver for Mesozoic glendonites, and supports the global extent of Valanginian to Hauterivian and Late Aptian global cooling. Surface temperatures during cool episodes of < 14 °C, as implied by the presence of glendonites at the …

Methane cold seeps: Paleo proxies, modern measurements, and instrument development
Marine cold seeps are one of the main conduits by which methane (CH4) from anoxic marine sediments, the largest CH4 reservoir on Earth’s surface, is transferred from the sediments into the ocean. Most of this CH4 is oxidized by microbes in the sediments, making the anaerobic oxidation of CH4 (AOM) …

Novel Electron Transfer Systems in Hyperthermophilic Methanogenic and Anaerobic Methanotrophic Archaea: F420-dependent Nitrite Reductase and [Fe-S] Cluster Assembling Thioredoxin
Methanogens produce methane as the end-product of their energy respiration, and these microbes can be found in various anaerobic environments. Their metabolisms and unique enzymes have continually expanded the boundaries of our knowledge about microbial energy conservation and opened the potential …
