, 2023 AbstractEstablishing symbiosis between bacteria and invertebrates can significantly enhance energy transfer efficiency between them, which may aid in shaping the flourishing community in deep-sea chemosynthetic ecosystems, including cold seeps, hydrothermal vents, and organic falls.

Deep-Sea Carbonates Are a Reservoir of Fossil Microbes Previously Inhabiting Cold Seeps
Frontiers in Marine Science, 2021 Carbonates are globally distributed particularly around deep-sea cold seeps. The embedded microbes are fossil records of the past bioprocess but metagenomes of the carbonates have not been fully studied.

, 2023 AbstractIn deep-sea chemosynthetic ecosystems, macrofaunal diversity and distribution are determined by geochemical environments generated by fluid seepage. The South China Sea is located in the northwestern Pacific Ocean with a passive continental shelf, containing over 40 seep sites.

Temporal variability of gas seeps offshore New Zealand: multi-frequency geoacoustic imaging of the Wairarapa area, Hikurangi margin [PDF]
, 2010 Cold seeps on Opouawe Bank, situated in around 1000 m water depth on the Hikurangi Margin offshore North Island. New Zealand, were investigated using multibeam bathymetry, 75 and 410 kHz sidescan sonar imagery, and 2–8 kHz Chirp sediment echosounder data.

Biomarker Indicators of Cold Seeps
, 2023 AbstractLipid biomarkers of seep carbonates and sediments retrieved from the Dongsha area, Shenhu, Site F and Haima in the South China Sea (SCS) over the last two decades were studied. Biomarker inventories, microbial consortia, seepage dynamics, and biogeochemical processes of anaerobic oxidation of methane (AOM), aerobic oxidation of methane (AeOM ...

Structure and Drivers of Cold Seep Ecosystems [PDF]
Oceanography, 2009 Submarine hydrocarbon seeps are geologically driven "hotspots" of increased biological activity on the seabed. As part of the HERMES project, several sites of natural hydrocarbon seepage in the European seas were investigated in detail, including mud volcanoes and pockmarks, in study areas extending from the Nordic margin, to the Gulf of Cádiz, to the ...

Acoustic and visual characterisation of methane-rich seabed seeps at Omakere Ridge on the Hikurangi Margin, New Zealand [PDF]
, 2010 Six active methane seeps and one cold-water reef that may represent a relict seep were mapped at Omakere Ridge on New Zealand's Hikurangi Margin during cruises SO191 and TAN0616. Hydroacoustic flares, interpreted to be bubbles of methane rising through

Chemotrophic Microbial Mats and Their Potential for Preservation in the Rock Record [PDF]
, 2009 Putative microbialites are commonly regarded to have formed in association with photosynthetic microorganisms, such as cyanobacteria. However, many modern microbial mat ecosystems are dominated by chemotrophic bacteria and archaea.
