TLDR
The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor sustains some of the richest ecosystems on the sea bed as discussed by the authors, which consumes around two orders of magnitude more oxygen than the surrounding sea floor as a result of the microbial consumption of seep methane.Abstract:
The leakage of cold, methane-rich fluids from subsurface reservoirs to the sea floor sustains some of the richest ecosystems on the sea bed. These cold-seep communities consume around two orders of magnitude more oxygen than the surrounding sea floor as a result of the microbial consumption of seep methane.read more

TL;DR: This Consensus Statement documents the central role and global importance of microorganisms in climate change biology and puts humanity on notice that the impact of climate change will depend heavily on responses of micro organisms, which are essential for achieving an environmentally sustainable future.

The interaction of climate change and methane hydrates
TL;DR: The synergy between warming climate and gas hydrate dissociation feeds a popular perception that global warming could drive catastrophic methane releases from the contemporary gas hydrates reservoir as mentioned in this paper, but no conclusive proof that hydrate-derived methane is reaching the atmosphere now, but more observational data and improved numerical models will better characterize the climate-hydrate synergy in the future.

Intercellular wiring enables electron transfer between methanotrophic archaea and bacteria
Gunter Wegener,Gunter Wegener,Viola Krukenberg,Dietmar Riedel,Halina E. Tegetmeyer,Antje Boetius,Antje Boetius +6 more
TL;DR: It is observed that under TAOM conditions, both ANME and the HotSeep-1 bacteria overexpress genes for extracellular cytochrome production and form cell-to-cell connections that resemble the nanowire structures responsible for interspecies electron transfer between syntrophic consortia of Geobacter.

Methane Feedbacks to the Global Climate System in a Warmer World
Joshua F. Dean,Jack J. Middelburg,Thomas Röckmann,Rien Aerts,Luke G. Blauw,Matthias Egger,Mike S. M. Jetten,Anniek E. E. de Jong,Ove H. Meisel,Olivia Rasigraf,Caroline P. Slomp,Michiel H. in 't Zandt,A. J. Dolman +12 more
TL;DR: In this article, the authors synthesize biological, geochemical, and physically focused CH4 climate feedback literature, bringing together the key findings of these disciplines, and discuss environment-specific feedback processes, including the microbial, physical, and geochemical interlinkages and the timescales on which they operate.

TL;DR: In this article, the authors synthesize current knowledge of the nature, extent and time and space scales of vent and seep interactions with background systems, and document an expanded footprint beyond the site of local venting or seepage with respect to elemental cycling and energy flux, habitat use, trophic interactions, and connectivity.

A marine microbial consortium apparently mediating anaerobic oxidation of methane
Antje Boetius,Katrin Ravenschlag,Carsten J. Schubert,Dirk Rickert,Friedrich Widdel,Armin Gieseke,Rudolf Amann,Bo Barker Jørgensen,Ursula Witte,Olaf Pfannkuche +9 more
TL;DR: In this article, the authors provide microscopic evidence for a structured consortium of archaea and sulphate-reducing bacteria, which are identified by fluorescence in situ hybridization using specific 16S rRNA-targeted oligonucleotide probes.

Sedimentary organic matter preservation: an assessment and speculative synthesis
John I. Hedges,Richard G. Keil +1 more
TL;DR: For example, in a recent paper as discussed by the authors, the authors investigated the mechanisms governing sedimentary organic matter preservation in marine sediments and found that organic preservation in the marine environment is < 0.5% efficient, and that the factors which directly determine preservation vary with depositional regime, but have in common a critical interaction between organic and inorganic materials over locally variable time scales.

Biogeochemical aspects of atmospheric methane
TL;DR: In this paper, the authors identify and evaluate several constraints on the budget of atmospheric methane, its sources, sinks and residence time, and construct a list of sources and sinks, identities, and sizes.

TL;DR: Evidence for a fourth pathway to produce oxygen is presented, possibly of considerable geochemical and evolutionary importance, and opens up the possibility that oxygen was available to microbial metabolism before the evolution of oxygenic photosynthesis.
