Macrofaunal ecology of sedimented hydrothermal vents in the Bransfield Strait, Antarctica

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.

Numerical Simulation Study of Seafloor Hydrothermal Circulation Based on HydrothermalFoam: A Case Study of the Wocan-1 Hydrothermal Field, Carlsberg Ridge, Indian Ocean

Journal of Marine Science and Engineering, 2023
Deep-sea hydrothermal circulation plays a pivotal role in the material and energy exchange in deep-sea environments, exerting significant influence on the evolution of seawater chemistry and global climate dynamics. Based on existing data and assumptions,

Effects of Substrate Composition and Subsurface Fluid Pathways on the Geochemistry of Seafloor Hydrothermal Deposits at the Lucky Strike Vent Field, Mid‐Atlantic Ridge

Geochemistry, Geophysics, Geosystems, 2022
The Lucky Strike vent field, located on the Mid‐Atlantic Ridge (MAR), is hosted on enriched mid‐ocean ridge basalt associated with the nearby Azores hotspot. In this study, we present bulk rock geochemistry coupled with in situ sulfur isotope analysis of

Distribution Patterns and Diversity of Sedimental Microbial Communities in the Tianxiu Hydrothermal Field of Carlsberg Ridge

Oceans
Hydrothermal vents, widely occurring along middle-ocean ridges and volcanic arcs, have been well-studied in vent-associated microbiology, mineralogy, and geochemistry. However, there are rarely investigations regarding the detailed microbial community in

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.

Deep-Sea Hydrothermal Vent and Impact-Generated Hydrothermal Vent Systems: Insights into the Origin of Life

Journal of Marine Science and Engineering
Studies of deep-sea hydrothermal vent systems have generated a spectrum of hypotheses concerning the origin of life on Earth. The present paper integrates recent literature surrounding three separate hydrothermal vent systems (Lost City in the mid ...

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 ...

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 ...
