THEO Concept Mission: Testing the Habitability of Enceladus's Ocean

, 2016
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar

Genomic variation in microbial populations inhabiting the marine subseafloor at deep-sea hydrothermal vents

Nature Communications, 2017
The warm subseafloor at deep-sea hydrothermal vents hosts diverse microbial communities. Here, Anderson et al. reconstruct 73 metagenome-assembled genomes from two geochemically distinct hydrothermal vent fields, showing different patterns of genomic ...

Energy Transfer Through Food Webs at Hydrothermal Vents: Linking the Lithosphere to the Biosphere [PDF]

Oceanography, 2012
Tectonic and volcanic processes that drive hydrothermal fluid flow and influence its chemistry also regulate the transfer of energy to hydrothermal vent ecosystems.

Chemical environments of submarine hydrothermal systems [PDF]

Perhaps because black-smoker chimneys make tremendous subjects for magazine covers, the proposal that submarine hydrothermal systems were involved in the origin of life has caused many investigators to focus on the eye-catching hydrothermal vents.

Biogeochemical Processes at Hydrothermal Vents: Microbes and Minerals, Bioenergetics, and Carbon Fluxes [PDF]

Oceanography, 2012
Hydrothermal vents are among the most biologically active regions of the deep ocean. However, our understanding of the limits of life in this extreme environment, the extent of biogeochemical transformation that occurs in the crust and overlying ocean ...

Phylogeny of hydrothermal vent Iphionidae, with the description of a new species (Aphroditiformia, Annelida)

ZooKeys, 2018
The scale-worm family Iphionidae consists of four genera. Of these, Thermiphione has two accepted species, both native to hydrothermal vents in the Pacific Ocean; T. fijiensis Miura, 1994 (West Pacific) and T. tufari Hartmann-Schröder, 1992 (East Pacific
