Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

open access: yes, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Experimental and simulation efforts in the astrobiological exploration of exooceans [PDF]

open access: yes, 2020
The icy satellites of Jupiter and Saturn are perhaps the most promising places in the Solar System regarding habitability. However, the potential habitable environments are hidden underneath km-thick ice shells.

Microorganisms from deep-sea hydrothermal vents [PDF]

open access: yesMarine Life Science & Technology, 2021
With a rich variety of chemical energy sources and steep physical and chemical gradients, hydrothermal vent systems offer a range of habitats to support microbial life. Cultivation-dependent and independent studies have led to an emerging view that diverse microorganisms in deep-sea hydrothermal vents live their chemolithoautotrophic, heterotrophic, or

Triassic hydrothermal chimneys from the Ordos Basin of Northern China

open access: yesScientific Reports, 2021
Because few well-preserved hydrothermal chimneys have been found in terrestrial sedimentary rocks, research on paleo-thermal vents in geological history is relatively sparse.

Research on Non-Invasive Laser Doppler Current Measurement for Hydrothermal Vents Flow Rates Profile [PDF]

open access: yesEPJ Web of Conferences, 2020
Hydrothermal vents play important roles in the dynamic process of the stratosphere and the circulation of energy materials. Nowadays, invasive devices such as vane-type flow meter and turbine flow meter are commonly utilized to estimate the flow rates of

Diffuse flow environments within basalt- and sediment-based hydrothermal vent ecosystems harbor specialized microbial communities [PDF]

open access: yes, 2013
Hydrothermal vents differ both in surface input and subsurface geochemistry. The effects of these differences on their microbial communities are not clear.

Isotopic niche variability in macroconsumers of the East Scotia Ridge (Southern Ocean) hydrothermal vents: What more can we learn from an ellipse? [PDF]

open access: yes, 2016
Aspects of between-individual trophic niche width can be explored through the isotopic niche concept. In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex.

Metals in the shell of Bathymodiolus azoricus from a hydrothermal vent site on the Mid-Atlantic Ridge [PDF]

open access: yes, 2007
Specimens of the mussel Bathymodiolus azoricus were collected from Menez Gwen, a relatively shallow (850 m) hydrothermal vent field on the Mid-Atlantic Ridge. Each bivalve shell (n = 21) was individually cleaned by selective chemical.

The NOAA Vents Program 1983 to 2013: Thirty Years of Ocean Exploration and Research [PDF]

open access: yesOceanography, 2015
Two seminal advances in the late 1970s in science and technology spurred the establishment of the National Oceanic and Atmospheric Administration (NOAA) Vents Program: the unexpected discovery of seafloor vents and chemosynthetic ecosystems on the ...
