Hydrocarbon seeps, deep sea extreme environments where deeply sourced fluids
discharge at the seabed, occur along continental margins across the globe. Energy-rich …

Humanity's search for extraterrestrial life is a modern manifestation of the exploratory and
curious nature that has led us through millennia of scientific discoveries. With the ongoing …

Discharge of gas-rich brines fuels productive chemosynthetic ecosystems in the deep sea. In
these salty, methanic and sulfidic brines, microbial communities adapt to specific niches …

In deep ocean hypersaline basins, the combination of high salinity, unusual ionic
composition and anoxic conditions represents significant challenges for microbial life. We …

Numerous marine hydrocarbon seeps have been discovered in the past three decades, the
majority of which are dominated by methane-rich fluids. However, an increasing number of …

Cold seeps create diverse habitats in the deep sea and play an important role in the global
carbon cycling. Anaerobic oxidation of methane (AOM) and biogenic mineralization are …

Cold seep ecosystems are developed from methane-rich fluids in organic rich continental
slopes, which are the source of various dense microbial and faunal populations. Extensive …

Submarine cold seeps have recently attracted significant attention and are among the most
effective indicators of gas hydrate in the oceans. In this study, remotely operated vehicle …

Hypersaline seafloor environments formed by brine seepage represent role model
examples of extreme marine ecosystems; they may for example help to identify potential …

“Candidatus Marithrix” is a recently described lineage within the group of large sulfur
bacteria (Beggiatoaceae, Gammaproteobacteria). This genus of bacteria comprises …
