The discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents in 1977
changed our view of biology. Chemosynthetic bacteria and archaea form the foundation of …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

Although initially viewed as oases within a barren deep ocean, hydrothermal vents and
methane seep chemosynthetic communities are now recognized to interact with surrounding …

The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

Organisms capable of autotrophic metabolism assimilate inorganic carbon into organic
carbon. They form an integral part of ecosystems by making an otherwise unavailable form …

Thermophilic and hyperthermophilic Archaea and Bacteria have been isolated from marine
hydrothermal systems, heated sediments, continental solfataras, hot springs, water heaters …

This review of material relevant to the Conference on Biosignature Preservation and
Detection in Mars Analog Environments summarizes the meeting materials and discussions …

Serpentinites are an important component of the oceanic crust generated in slow to
ultraslow spreading settings. In this context, the MOHO likely corresponds to a hydration …

Viruses are the most abundant biological entities in the oceans and a pervasive cause of
mortality of microorganisms that drive biogeochemical cycles. Although the ecological and …

Reviews of the sulfur cycle from a biogeochemical or microbiological perspective have
recently been presented, eg by Amend et al.(2004) and Canfield et al.(2005). The latter …
