Vertically distinct microbial communities in the Mariana and Kermadec trenches. [PDF]

PLoS ONE, 2018
Hadal trenches, oceanic locations deeper than 6,000 m, are thought to have distinct microbial communities compared to those at shallower depths due to high hydrostatic pressures, topographical funneling of organic matter, and biogeographical isolation ...

Genomic Characterization of a Novel Gut Symbiont From the Hadal Snailfish

Frontiers in Microbiology, 2020
Hadal trenches are characterized by not only high hydrostatic pressure but also scarcity of nutrients and high diversity of viruses. Snailfishes, as the dominant vertebrates, play an important role in hadal ecology.

Hydrostatic pressure induces transformations in the organic matter and microbial community composition of marine snow particles

Communications Earth & Environment, 2023
In the hadal zone of the ocean (6–11 km), the characteristics of sinking marine snow particles and their attached microbial communities remain elusive, despite their potential importance for benthic life thriving at extreme pressures (60–110 MPa).

The phylogeny and metabolic potentials of an n-alkane-degrading Venatorbacter bacterium isolated from deep-sea sediment of the Mariana Trench

Frontiers in Microbiology, 2023
Recently, several reports showed that n-alkanes were abundant in the hadal zone, suggesting that n-alkanes could be an important source of nutrients for microorganisms in hadal ecosystems.

Spatial variations of microbial communities in abyssal and hadal sediments across the Challenger Deep [PDF]

PeerJ, 2019
Microbial communities in hadal sediments are least explored in hadal zone (>6,000 m), especially in the Challenger Deep with high pressure (∼110 M pa at the bottom).

Fishes of the hadal zone including new species, in situ observations and depth records of Liparidae [PDF]

, 2016
Observations and records for fish exceeding 6000m deep are few and often spurious. Recent developments in accessing and sampling the hadal zone 6000–11,000m) have led to an acceleration in new findings in the deep subduction trenches, particularly in the

Distinctive signatures of pathogenic and antibiotic resistant potentials in the hadal microbiome

Environmental Microbiome, 2022
Background Hadal zone of the deep-sea trenches accommodates microbial life under extreme energy limitations and environmental conditions, such as low temperature, high pressure, and low organic matter down to 11,000 m below sea level.

Deepest known novel species of the genus Ophiuroglypha Hertz, 1927 (Echinodermata: Ophiuroidea) from the central rift zone, Philippine Sea

European Journal of Taxonomy, 2023
A new species of brittle star was collected in 2021 by the manned submersible “Fendouzhe” from the central rift zone deep waters, Philippine Sea, at a depth of 7729 m. It is described as Ophiuroglypha fendouzhe sp.
