Background The deep sea harbors the majority of the microbial biomass in the ocean and is a key site for organic matter (OM) remineralization and storage in the biosphere. Microbial metabolism in the deep ocean is greatly controlled by the generally depleted but periodically fluctuating supply of OM. Currently, little is known about metabolic poten...

Background: The deep-sea harbors the majority of the microbial biomass on Earth, and is a key site for organic matter (OM) remineralization and storage in the biosphere. Microbial metabolisms in the deep ocean are greatly controlled by the generally depleted but periodically fluctuating supply of OM. Currently, little is known about metabolic poten...

The landward wall of the New Britain Trench (NBT) is an active continental margin. Unlike passive margins, it lacks a continental rise and the abyssal plain, and has a steep continental slope ending in an oceanic trench. Although the trench systems are receiving more and more attentions, our understanding of the microbiology of the NBT and its tren...
