A New Method for Training CycleGAN to Enhance Images of Cold Seeps in the Qiongdongnan Sea [PDF]

Sensors, 2023
Clear underwater images can help researchers detect cold seeps, gas hydrates, and biological resources. However, the quality of these images suffers from nonuniform lighting, a limited range of visibility, and unwanted signals.

Active pathways of anaerobic methane oxidization in deep-sea cold seeps of the South China Sea [PDF]

Microbiology Spectrum, 2023
Anaerobic oxidation of methane (AOM) is critical for controlling methane emissions from deep-sea cold seeps. Microbial groups associated with different AOM processes have been briefly investigated, but the AOM activities associated with the utilization ...

Biogeographic distributions of microbial communities associated with anaerobic methane oxidation in the surface sediments of deep-sea cold seeps in the South China Sea [PDF]

Frontiers in Microbiology, 2022
Cold seeps are oasis for the microbes in the deep-sea ecosystems, and various cold seeps are located along the northern slope of the South China Sea (SCS).

Microbial Eukaryotes Associated With Sediments in Deep-Sea Cold Seeps [PDF]

Frontiers in Microbiology, 2021
Microbial eukaryotes are key components of the marine food web, but their distribution in deep-sea chemosynthetic ecosystems has not been well studied. Here, high-throughput sequencing of the 18S rRNA gene and network analysis were applied to investigate

Cold seeps are potential hotspots of deep-sea nitrogen loss driven by microorganisms across 21 phyla [PDF]

Nature Communications
Nitrogen bioavailability, governed by fixation and loss processes, is crucial for oceanic productivity and global biogeochemical cycles. The key nitrogen loss organisms—denitrifiers and anaerobic ammonium-oxidizing (anammox) bacteria—remain poorly ...

Phylogenetic diversity of functional genes in deep-sea cold seeps: a novel perspective on metagenomics [PDF]

Microbiome, 2023
Background Leakages of cold, methane-rich fluids from subsurface reservoirs to the sea floor are termed cold seeps. Recent exploration of the deep sea has shed new light on the microbial communities in cold seeps.

Evidence of microbial reductive dehalogenation in deep-sea cold seeps and its implications for biogeochemical cycles [PDF]

Microbiome
Background Reductive dehalogenation is crucial for halogen cycling and environmental remediation, yet its ecological role is not completely understood, especially in deep-sea environments. To address this gap, we investigated the diversity and expression

Deep-sea corals near cold seeps associate with sulfur-oxidizing chemoautotrophs in the family Ca. Thioglobaceae [PDF]

Microbiome
Background Corals are known for their symbiotic relationships, yet there is limited evidence of chemoautotrophic associations. This is despite some corals occurring near cold seeps where chemosymbiotic fauna abound including mussels that host sulfur ...

Transcriptomic analysis reveals insights into deep-sea adaptations of the dominant species, Shinkaia crosnieri (Crustacea: Decapoda: Anomura), inhabiting both hydrothermal vents and cold seeps [PDF]

BMC Genomics, 2019
Background Hydrothermal vents and cold seeps are typical deep-sea chemosynthetically-driven ecosystems that allow high abundance of specialized macro-benthos.

Population genetic structure in Sabatieria (Nematoda) reveals intermediary gene flow and admixture between distant cold seeps from the Mediterranean Sea [PDF]

BMC Evolutionary Biology, 2017
Background There is a general lack of information on the dispersal and genetic structuring for populations of small-sized deep-water taxa, including free-living nematodes which inhabit and dominate the seafloor sediments. This is also true for unique and
