An Epifaunal Community Succession Sequence Driven by the Biogeochemical Footprint With Different Methane Seepage Intensity of the Deep Seafloor

Earth's Future, 2023
Methane seepage, generated from natural processes or gas hydrate dissociation, drives the development of cold seep ecosystems and leads to atmosphere methane emission, thereby influencing climate change.

Identification of fossil worm tubes from Phanerozoic hydrothermal vents and cold seeps [PDF]

, 2017
One of the main limitations to understanding the evolutionary history of hydrothermal vent and cold seep communities is the identification of tube fossils from ancient deposits.

Geochemical characteristics of sediment and pore water affected by cold seeps in southern South China Sea

Frontiers in Marine Science, 2023
Cold seep, characterized by active material circulation and methane seepage, is of great importance to reconstruct the paleo-marine environment and trace the origin of life and the occurrence of minerals. Southern South China Sea (SCS) with ample oil and

Let's Make a Tubeworm! [PDF]

In this activity, centered on the ecology of a cold-seep community, students will investigate how deep-sea tube worms are adapted for a symbiotic relationship that allows them to survive.

Transcription, signaling receptor activity, oxidative phosphorylation, and fatty acid metabolism mediate the presence of closely related species in distinct intertidal and cold-seep habitats [PDF]

, 2015
Bathyal cold seeps are isolated extreme deep-sea environments characterized by low species diversity while biomass can be high. The Hakon Mosby mud volcano (Barents Sea, 1,280 m) is a rather stable chemosynthetic driven habitat characterized by prominent

Trophic adaptation strategies of deep-Sea fish in cold seep environments

Water Biology and Security
The diversity of marine habitats influences fish trophic niches and adaptation strategies. This study investigated fish trophic niches in cold seep and adjacent areas of the South China Sea in August 2023 using stable isotope techniques.

First documented record of a living solemyid bivalve in a pockmark of the Nile Deep-sea Fan (eastern Mediterranean Sea) [PDF]

, 2011
A living specimen of a solemyid bivalve was collected at bathyal depths near a pockmark in the Nile Deep-sea Fan (eastern Mediterranean) and is here presented.

Microbial diversity and biogeochemical cycling potential in deep-sea sediments associated with seamount, trench, and cold seep ecosystems

Frontiers in Microbiology, 2022
Due to their extreme water depths and unique physicochemical conditions, deep-sea ecosystems develop uncommon microbial communities, which play a vital role in biogeochemical cycling.

Evidence of microbial activity from a shallow water whale fall (Voghera, northern Italy) [PDF]

, 2012
The fossil bones, associated carbonate cements and enclosing concretion of a Miocene mysticete from inner shelf deposits (Monte Vallassa Formation, northern Italy) were analyzed for evidence of microbial activity. Optical and scanning electron microscopy,

Diversity and Distribution of Methanotrophic Archaea at Cold Seeps [PDF]

Applied and Environmental Microbiology, 2005
ABSTRACT In this study we investigated by using 16S rRNA-based methods the distribution and biomass of archaea in samples from (i) sediments above outcropping methane hydrate at Hydrate Ridge (Cascadia margin off Oregon) and (ii) massive microbial mats enclosing carbonate reefs (Crimea area, Black Sea). The archaeal diversity was
