Bioturbation in the hadal zone [PDF]

Nature Communications
The hadal zone, >6 km deep, remains one of the least understood ecosystems on Earth. We address bioturbational structures in sediment cores from depths exceeding 7.5 km, collected during the IODP Expedition 386 in the Japan Trench. Micro-CT imaging on 20

Genomic evidence on the distribution and ecological function of Pseudomonas in hadal zone [PDF]

BMC Microbiology
The hadal zone is the deepest region on Earth. It serves as a depositional zone for the sinking matter from surface ocean and continental margin, aided by its unique V-shaped structure.

Vertical Distribution of Microbial Eukaryotes From Surface to the Hadal Zone of the Mariana Trench [PDF]

Frontiers in Microbiology, 2018
Marine microbial eukaryotes are ubiquitous, comprised of phylogenetically diverse groups and play key roles in microbial food webs and global biogeochemical cycling. However, their vertical distribution in the deep sea has received little attention.

The hadal zone is an important and heterogeneous sink of black carbon in the ocean [PDF]

Communications Earth & Environment, 2022
Black carbon accumulation rates in hadal trenches in the deepest regions of the oceans could be seven-fold higher than the global ocean average, according to geochemical and isotopic analyses of sediments from six trenches in the Pacific Ocean.

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

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

Composition and Ecological Roles of the Core Microbiome along the Abyssal-Hadal Transition Zone Sediments of the Mariana Trench

Microbiology Spectrum, 2022
The unique geological features of hadal trenches are known to influence both the structure and ecological function of microbial communities. It is also well known that heterotrophs and chemoautotrophs dominate the hadal and abyssal pelagic zones ...

Scientific and technological progress in the microbial exploration of the hadal zone. [PDF]

Mar Life Sci Technol, 2022
The hadal zone is the deepest point in the ocean with a depth that exceeds 6000 m. Exploration of the biological communities in hadal zone began in the 1950s (the first wave of hadal exploration) and substantial advances have been made since the turn of the twenty-first century (the second wave of hadal exploration), resulting in a focus on the hadal ...

Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms [PDF]

Microbiome, 2020
Background Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations.

Virioplankton assemblages from challenger deep, the deepest place in the oceans [PDF]

iScience, 2022
Summary: Hadal ocean biosphere, that is, the deepest part of the world’s oceans, harbors a unique microbial community, suggesting a potential uncovered co-occurring virioplankton assemblage.

The genome of a hadal sea cucumber reveals novel adaptive strategies to deep-sea environments

iScience, 2022
Summary: How organisms cope with coldness and high pressure in the hadal zone remains poorly understood. Here, we sequenced and assembled the genome of hadal sea cucumber Paelopatides sp.
