Microbial communities of deep-sea methane seeps at Hikurangi continental margin (New Zealand). [PDF]

PLoS ONE, 2013
The methane-emitting cold seeps of Hikurangi margin (New Zealand) are among the few deep-sea chemosynthetic ecosystems of the Southern Hemisphere known to date. Here we compared the biogeochemistry and microbial communities of a variety of Hikurangi cold

Different Nitrogen Sources Fuel Symbiotic Mussels at Cold Seeps

Frontiers in Marine Science, 2022
Cold seeps globally host dense unique oasis-type ecosystems, mainly fuelled by chemosynthetic microorganisms via reduced gases such as methane and hydrogen sulfide.

Production of Labile Protein-Like Dissolved Organic Carbon Associated With Anaerobic Methane Oxidization in the Haima Cold Seeps, South China Sea

Frontiers in Marine Science, 2021
Cold seeps where methane-rich fluids escape from the seafloor generally support enormous biomass of chemosynthetic organisms and associated fauna. In addition to transporting a great amount of methane toward the seafloor, cold seeps also contribute to ...

Using a Ladder of Seeps With Computer Decision Processes to Explore for and Evaluate Cold Seeps on the Costa Rica Active Margin

Frontiers in Earth Science, 2021
Natural seeps occur at the seafloor as loci of fluid flow where the flux of chemical compounds into the ocean supports unique biologic communities and provides access to proxy samples of deep subsurface processes.

Genomic and enzymatic evidence of acetogenesis by anaerobic methanotrophic archaea

Nature Communications, 2020
Ocean cold seeps are poorly understood relative to related systems like hydrothermal vents. Here the authors use high pressure bioreactors and microbial communities from a cold seep mud volcano and find a previously missing step of methane conversion to ...

Efficiency and adaptability of the benthic methane filter at Quepos Slide cold seeps, offshore of Costa Rica [PDF]

Biogeosciences, 2015
Large amounts of methane are delivered by fluids through the erosive forearc of the convergent margin offshore of Costa Rica and lead to the formation of cold seeps at the sediment surface.

Magnesium geochemistry of authigenic carbonate at marine cold seep

Frontiers in Marine Science
Cold seeps, featured by their extremely methane-rich sedimentary environments, play a significant role in the geological history and are common in marine sediments across the seafloor.

Deep-sea viral diversity and their role in host metabolism of complex organic matter. [PDF]

Nat Commun
Viruses exert a pervasive influence on biogeochemical cycles in deep-sea ecosystems. Cold seeps and seamounts, globally distributed across the oceans and harboring diverse microbial communities, remain largely unexplored regarding their viral inhabitants

Archives of short-term fluid flow dynamics and possible influence of human activities at methane seeps: Evidence from high-resolution element geochemistry of chemosynthetic bivalve shells

Frontiers in Marine Science, 2022
The natural dynamics of fluid flow at methane seeps and increasingly human activities influence the biogeochemistry of the microenvironment and further determine the activity of the chemosynthetic communities within these ecosystems.
