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 ...

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

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

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]
MicrobiomeBackground 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]
MicrobiomeBackground 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 ...
