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

open access: yesMicrobiome, 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.

A comprehensive genomic catalog from global cold seeps

open access: yesScientific Data, 2023
AbstractCold seeps harbor abundant and diverse microbes with tremendous potential for biological applications and that have a significant influence on biogeochemical cycles. Although recent metagenomic studies have expanded our understanding of the community and function of seep microorganisms, knowledge of the diversity and genetic repertoire of ...

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

open access: yesDeep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

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

open access: yesNature 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 ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Disentangling the Functional Role of Fungi in Cold Seep Sediment

open access: yesMicrobiology Spectrum, 2023
The challenges we face when analyzing eukaryotic metagenomic and metatranscriptomic data sets have hindered our understanding of cold seep fungi and microbial eukaryotes. This fact does not make the mycobiota any less critical in mediating cold seep biogeochemistry.

Viruses in the sediments around the trenches harbor diverse survival mechanisms

open access: yesiMetaOmics, EarlyView.
Deep‐sea trenches are the deepest and most isolated environments in the global ocean but the diversity and adaptation of the viral communities remain poorly characterized. In this study, 5563 viral operational taxonomic units (vOTUs) were identified from sediments of the Yap Trench and Western Caroline Basin.
