Sinking Particle Fluxes at the Jan Mayen Hydrothermal Vent Field Area from Short-Term Sediment Traps

Journal of Marine Science and Engineering
The mixing of hydrothermal vent fluids with deep ocean water and near-vent pelagic matter results in particle populations with a complex composition consisting of hydrothermally derived, rock-forming, and biogenic particles.

Reproductive adaptations of the hydrothermal vent crab Xenograpus testudinatus: An isotopic approach.

PLoS ONE, 2019
The vent crab Xenograpsus testudinatus was firstly discovered in 2000 at the hydrothermal vent field off the coast of Kueishan Island. The present study attempts to understand the adaptive reproduction of this crab living in an extreme environment by ...

Discovery of new hydrothermal activity and chemosynthetic fauna on the Central Indian Ridge at 18°-20° S. [PDF]

PLoS ONE, 2012
Indian Ocean hydrothermal vents are believed to represent a novel biogeographic province, and are host to many novel genera and families of animals, potentially indigenous to Indian Ocean hydrothermal systems.

Complete mitochondrial genome of the hydrothermal vent barnacle Eochionelasmus ohtai (Cirripedia, Thoracica)

Mitochondrial DNA. Part B. Resources, 2018
Thoracican barnacles are common in hydrothermal vent fields. Here, we characterized the first mitogenome of a hydrothermal vent barnacle. The mitogenome of Eochionelasmus ohtai was 15,585 bp in length and had the typical pancrustacean gene arrangement ...

Scalable, Bottom‐Up Synthesis of Transition Metal–Doped Quantum Confined, 1D Titanate‐Based Lepidocrocite Nanofilaments, Their Electronic Structures and Oxygen Evolution Reactivity

Advanced Materials Interfaces, EarlyView.
Quantum‐confined lepidocrocite titanate nanofilaments are doped, bottom‐up, with Mn+2, Fe+2, Co+2, Ni+2, and Cu+2 to tune electronic structure and catalysis. Doping narrows the bandgap—by up to ∼0.8 eV—and extends visible absorption. Ni‐doped filaments accelerate oxygen evolution (319 mV at 10 mA cm−2) and TM‐doped samples rapidly degrade rhodamine 6G (

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Neuroanatomy of a hydrothermal vent shrimp provides insights into the evolution of crustacean integrative brain centers

eLife, 2019
Alvinocaridid shrimps are emblematic representatives of the deep hydrothermal vent fauna at the Mid-Atlantic Ridge. They are adapted to a mostly aphotic habitat with extreme physicochemical conditions in the vicinity of the hydrothermal fluid emissions ...

Life in extreme environments: Hydrothermal vents [PDF]

Proceedings of the National Academy of Sciences, 2000
Eruption of volcanic rocks at the midocean ridges is the major mechanism by which heat is lost from the interior of the Earth. Approximately one-third of the heat is removed from the spreading centers by convective circulation of seawater (1). The magnitude of this heat loss requires that the entire volume of the oceans circulates through the midocean ...
