Hadal Biodiversity, Habitats and Potential Chemosynthesis in the Java Trench, Eastern Indian Ocean

Frontiers in Marine Science, 2022
The Java Trench is the only subduction trench in the Indian Ocean that extends to the hadal zone (> 6,000 m water depth), and except for sevenbenthic trawls acquired around the 1950s, there has been little to no sampling at hadal depths undertaken ...

Proliferation of hydrocarbon-degrading microbes at the bottom of the Mariana Trench [PDF]

Microbiome, 2019
Background The Mariana Trench is the deepest known site in the Earth’s oceans, reaching a depth of ~ 11,000 m at the Challenger Deep. Recent studies reveal that hadal waters harbor distinctive microbial planktonic communities.

Hadal Snailfishes (Teleostei: Liparidae) Extend Across Multiple Trenches: Molecular Insights and Implications for Taxonomic Nomenclature [PDF]

Ecology and Evolution
The hadal zone, Earth's deepest oceanic region, is defined by distinct geological features and hosts a variety of endemic species, including the Liparidae Gill, 1861 (snailfishes).

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.

Event Stratigraphy in a Hadal Oceanic Trench: The Japan Trench as Sedimentary Archive Recording Recurrent Giant Subduction Zone Earthquakes and Their Role in Organic Carbon Export to the Deep Sea

Frontiers in Earth Science, 2019
Hadal trenches are the deepest places on Earth and are important foci for natural carbon sequestration. Much of the sedimentary sequences that accumulate within hadal trenches have been linked to widespread slope sediment remobilization events, triggered

The HOG signal pathway contributes to survival strategies of the piezo-tolerant fungus Aspergillus sydowii DM1 in hadal sediments [PDF]

Applied and Environmental Microbiology
The hadal zone, one of Earth’s most extreme ecosystems, harbors diverse and unique microbial communities adapted to its harsh environmental conditions, including high hydrostatic pressure (HHP) and low temperatures.

Clear niche partitioning of nitrite-oxidizing bacteria from the bottom and the slope of Mariana Trench [PDF]

Microbiome
Background The hadal zone, characterized by extreme hydrostatic pressure and geographic isolation, hosts microbial communities uniquely adapted to these harsh conditions.

Faunal biodiversity of the lower abyssal and hadal zones of the Japan, Ryukyu and Izu-Ogasawara trenches (NW Pacific Ocean; 4534-9775 m) [PDF]

Biodiversity Data Journal
In-situ video-based observations collected using multiple platforms are increasingly used for biodiversity assessments at abyssal and hadal depths, sometimes complemented by physical sampling.

Microbial population structure along the water columns and sediments in the Diamantina and Kermadec trenches [PDF]

BMC Biology
Background Microbes are widespread from the marine surface to the hadal zones and play a significant role in global biogeochemical cycling. Physicochemical properties of hadal zone shift with depth, in turn influencing the distribution profiles ...
