Removal of dissolved organic carbon in the West Pacific hadal zones [PDF]

Nature Communications
The deep oceans are environments of complex carbon dynamics that have the potential to significantly impact the global carbon cycle. However, the role of hadal zones, particularly hadal trenches (water depth > 6 km), in the oceanic dissolved organic ...

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.

The supergiant amphipod Alicella gigantea may inhabit over half of the world’s oceans [PDF]

Royal Society Open Science
The deep-sea amphipod Alicella gigantea Chevreux, 1899, currently known as the world’s largest amphipod, inhabits depths of the lower abyssal and upper hadal zones. Historically, it has been sampled or observed in situ infrequently relative to other deep-

Microbial community structure and functional traits involved in the adaptation of culturable bacteria within the gut of amphipods from the deepest ocean [PDF]

Microbiology Spectrum
The Hadal Zone is acknowledged for its extreme environmental conditions, especially high hydrostatic pressures. The dominant scavengers in the Hadal Zone, Hadal amphipods, fulfill vital roles in the Hadal food web and ecological niches. However, research

Genomic and physiological properties of Anoxybacterium hadale gen. nov. sp. nov. reveal the important role of dissolved organic sulfur in microbial metabolism in hadal ecosystems [PDF]

Frontiers in Microbiology
Hadal zones account for the deepest 45% of the oceanic depth range and play an important role in ocean biogeochemical cycles. As the least-explored aquatic habitat on earth, hadal ecosystems contain a vast diversity of so far uncultured microorganisms ...

Trimethylamine N-Oxide (TMAO) and Trimethylamine (TMA) Determinations of Two Hadal Amphipods

Journal of Marine Science and Engineering, 2022
Hadal trenches are a unique habitat with high hydrostatic pressure, low temperature and scarce food supplies. Amphipods are the dominant scavenging metazoan species in this ecosystem.
