Evidence for early life in Earth’s oldest hydrothermal vent precipitates [PDF]
Nature, 2017 Although it is not known when or where life on Earth began, some of the earliest habitable environments may have been submarine-hydrothermal vents. Here we describe putative fossilized microorganisms that are at least 3,770 million and possibly 4,280 ...

The Discovery of New Deep-Sea Hydrothermal Vent Communities in the Southern Ocean and Implications for Biogeography [PDF]
PLoS Biology, 2012 Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977, numerous vent sites and endemic faunal assemblages have been found along mid-ocean ridges and back-arc basins at low to mid latitudes.

Macrofaunal ecology of sedimented hydrothermal vents in the Bransfield Strait, Antarctica [PDF]
Frontiers in Marine Science, 2016 Sedimented hydrothermal vents, where hot, mineral-rich water flows through sediment, are poorly understood globally, both in their distribution and the ecology of individual vent fields.

Thermotogota diversity and distribution patterns revealed in Auka and JaichMaa ‘ja ‘ag hydrothermal vent fields in the Pescadero Basin, Gulf of California [PDF]
PeerJDiscovering new deep hydrothermal vent systems is one of the biggest challenges in ocean exploration. They are a unique window to elucidate the physical, geochemical, and biological processes that occur on the seafloor and are involved in the evolution ...

Do Hydrothermal Shrimp Smell Vents? [PDF]
Insects, 2021 Deep-sea species endemic to hydrothermal vents face the critical challenge of detecting active sites in a vast environment devoid of sunlight. This certainly requires specific sensory abilities, among which olfaction could be a relevant sensory modality,

Iron and sulfide nanoparticle formation and transport in nascent hydrothermal vent plumes
Nature Communications, 2019 Deep-sea hydrothermal vents are a significant source of dissolved metals to the global oceans, producing midwater plumes enriched in metals that are transported thousands of kilometers from the vent source.

Transcriptomics of the Anthopleura Sea Anemone Reveals Unique Adaptive Strategies to Shallow‐Water Hydrothermal Vent [PDF]
Ecology and EvolutionThe nonsymbiotic sea anemone Anthopleura nigrescens dominates the shallow‐water hydrothermal vents off the coast of Kueishan Island, Taiwan. These vents represent some of the world's most extreme environments, with recorded pH values as low as 1.52 and ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
