Voltammetric Investigation Of Hydrothermal Iron Speciation

Frontiers in Marine Science, 2016
Hydrothermal vent fluids are highly enriched in iron (Fe) compared to ambient seawater, and organic ligands may play a role in facilitating the transport of some hydrothermal Fe into the open ocean.

An atlas of protected hydrothermal vents

Marine Policy, 2019
Abstract Active hydrothermal vents are valued worldwide because of the importance of their biodiversity and their influence on scientific discovery and insight about life on Earth and elsewhere in the Universe. There exist at least 20 areas and area networks with conservation measures for deep-sea hydrothermal vents, established by 11 countries and ...

The Control of End‐Member Iron‐to‐Sulfide Ratios on Hydrothermal Plume Geochemistry at the Rainbow, Broken Spur, and Lost City Vent Fields in the Mid‐Atlantic Ridge

Geochemistry, Geophysics, Geosystems
The Mid‐Atlantic Ridge (MAR) represents a unique tectonic environment hosting distinct hydrothermal vent fields. Considering the growing interest in understanding the role of hydrothermal vents in both local and global ocean systems, the MAR offers an ...

The discovery of new deep-sea hydrothermal vent communities in the southern ocean and implications for biogeography.

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.

Three‐Dimensional Spatially Constrained Sulfur Isotopes Highlight Processes Controlling Sulfur Cycling in the Near Surface of the Iheya North Hydrothermal System, Okinawa Trough

Geochemistry, Geophysics, Geosystems, 2018
Modern seafloor hydrothermal systems are unique environments in which many of the Earth's reservoirs, including the hydrosphere, biosphere, and geosphere, dynamically interact. Analysis of spatially constrained sulfur isotope compositions from fluids and

Functional metagenomic investigations of microbial communities in a shallow-sea hydrothermal system.

PLoS ONE, 2013
Little is known about the functional capability of microbial communities in shallow-sea hydrothermal systems (water depth of

Ocean circulation contributes to genetic connectivity of limpet populations at deep‐sea hydrothermal vents in a back‐arc basin

Evolutionary Applications
For endemic benthos inhabiting hydrothermal vent fields, larval recruitment is critical for population maintenance and colonization via migration among separated sites. The vent‐endemic limpet, Lepetodrilus nux, is abundant at deep‐sea hydrothermal vents

Sulfur metabolizing microbes dominate microbial communities in Andesite-hosted shallow-sea hydrothermal systems.

PLoS ONE, 2012
To determine microbial community composition, community spatial structure and possible key microbial processes in the shallow-sea hydrothermal vent systems off NE Taiwan's coast, we examined the bacterial and archaeal communities of four samples ...

Natural warming differentiates communities and increases diversity in deep-sea Ridge Flank Hydrothermal Systems

Communications Biology
Ridge Flank Hydrothermal Systems have discrete pockets of fluid discharge that mimic climate-induced ocean warming. Unlike traditional hydrothermal fluids, those discharged by Ridge Flank Hydrothermal Systems have a chemical composition indistinguishable

Electricity generation from hydrothermal vents

IOP Conference Series: Earth and Environmental Science, 2016
Hydrothermal vent is a kind of manifestation of geothermal energy on seabed. It produces high temperature fluid through a hole which has a diameter in various range between several inches to tens of meters. Hydrothermal vent is mostly found over ocean ridges.
