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

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 ...

A new predator connecting the abyssal with the hadal in the Kuril-Kamchatka Trench, NW Pacific [PDF]

PeerJ, 2018
The bathyal to hadal deep sea of north-west Pacific Ocean was recently intensively sampled during four international expeditions (KuramBio I and II, SoJaBio and SokhoBio). A large amphipod, Rhachotropis saskia n.

Hadal water biogeochemistry over the Izu–Ogasawara Trench observed with a full-depth CTD-CMS [PDF]

Ocean Science, 2018
Full-depth profiles of hydrographic and geochemical properties at the Izu–Ogasawara Trench were observed for the first time using a CTD-CMS (conductivity–temperature–depth profiler with carousel multiple sampling) system.

Anammox bacteria drive fixed nitrogen loss in hadal trench sediments. [PDF]

Proc Natl Acad Sci U S A, 2021
Benthic N2 production by microbial denitrification and anammox is the largest sink for fixed nitrogen in the oceans. Most N2 production occurs on the continental shelves, where a high flux of reactive organic matter fuels the depletion of nitrate close ...

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 ...

Microbial community structure in hadal sediments: high similarity along trench axes and strong changes along redox gradients [PDF]

, 2021
Hadal trench sediments are hotspots of biogeochemical activity in the deep sea, but the biogeochemical and ecological factors that shape benthic hadal microbial communities remain unknown.

Geology, environment, and life in the deepest part of the world’s oceans

The Innovation, 2021
Summary: The hadal zone, mostly comprising of deep trenches and constituting of the deepest part of the world’s oceans, represents the least explored habitat but one of the last frontiers on our planet.

Megafaunal Community Structure From the Abyssal to Hadal Zone in the Yap Trench

Frontiers in Marine Science, 2021
Hadal trenches remain one of the unexplored ocean ecosystems due to the challenges of sampling at great depths. It is still unclear how a faunal community changes from the abyssal to the hadal zone, and which environmental variables are the key impacting

Metagenomic Insights Into the Structure and Function of Intestinal Microbiota of the Hadal Amphipods

Frontiers in Microbiology, 2021
Hadal trenches are the deepest known areas of the ocean. Amphipods are considered to be the dominant scavengers in the hadal food webs. The studies on the structure and function of the hadal intestinal microbiotas are largely lacking.
