The paper investigates anaerobic methane oxidation in the Orca Basin, identifying ANME-2a's role at high salinity and revealing microbial communities involved in methane cycling.

The paper investigates pressure effects on microbial activity in the Puerto Rico Trench, finding that piezophily dominates subseafloor communities below 20 meters below seafloor.

The paper presents deeply-sequenced metagenomes and over 1000 draft genomes from the deep ocean to study microbial communities across depth gradients.

The paper investigates microbial N2O reduction in sulfidic waters, finding that Proterozoic oceans likely had lower N2O emissions due to active N2O reduction under euxinic conditions.

This study identifies widespread and diverse deep-sea chemoautotrophs beyond nitrifiers, revealing their genetic potential for carbon fixation and impact on the carbon cycle.

The paper analyzes metagenomic data to show that rubisco-encoding organisms, particularly from SAR324 and gammaproteobacteria, dominate carbon fixation potential in the dark ocean.

The paper investigates nifH-containing organisms at marine cold seeps using amplicon sequencing and qPCR, finding diverse diazotrophs and highlighting seeps as diazotrophy hotspots.

The paper identifies a Prochlorococcus lineage in oxygen deficient zones that expresses both form I and form II rubiscos, suggesting an adaptation to low oxygen environments.

This study shows urea is a major nitrogen source for deep-sea microbes and supports nitrification, fueling chemoautotrophy in the dark ocean.

This paper introduces a read cloud metagenomic sequencing approach combined with a new assembler, Athena, to generate high-quality microbial genome drafts from human and marine microbiomes without culturing.
