Metabolically diverse microorganisms mediating hydrocarbon cycling in the subseafloor sediment of the Challenger Deep [PDF]

mBio
Hadal subseafloor sediments host abundant and active microbial biosphere with considerable heterotrophic activity. However, carbon and nutrient cycling processes and mechanisms driven by hadal subsurface microorganisms remain poorly understood.

Three-layer circulation in the world deepest hadal trench [PDF]

Nature Communications
The Challenger Deep (CD) is the deepest known hadal trench in the world. Due to challenges in data sampling at extreme ocean depths, the Lower Circumpolar Deep Water (LCDW) transport and ocean circulation structure in the CD remain unclear.

Alkane degradation mechanism of Mixta calida HXX308 isolated from sediment of the Mariana Trench [PDF]

Frontiers in Microbiology
The Challenger Deep of the Mariana Trench, which is the deepest site in the ocean, contains rich deposits of n-alkanes in its sediments. However, the alkane metabolic processes of the bacteria in this extreme environment were not well understood. In this

A Dual-Path Attention and Multi-Scale Fusion Network for Crop Disease and Pest Identification [PDF]

Entropy
Crop diseases and pests severely threaten global food security. While deep learning has shown promise in controlled settings, real-world field conditions—characterized by complex backgrounds, variable lesion scales, and high inter-class similarity—remain

Fungal Abundance and Diversity in the Mariana Trench, the Deepest Ecosystem on Earth [PDF]

Journal of Fungi
Hadal trenches host abundant and diversified benthic prokaryotic assemblages, but information on benthic fungi is still extremely limited. We investigated the fungal abundance and diversity in the Challenger Deep (at ca.

Physical and Mechanical Properties of Deep Oceanic Sediments Cored from the Bottom of Challenger Deep, Mariana Trench

Geofluids, 2021
The deep oceanic sediments were collected from the Challenger Deep in the southwestern part of the Mariana Trench. Considering the salt in the pore water, a modified method for determining the physical and mechanical properties of the deep-sea sediments ...

The Hadal Amphipod Hirondellea gigas possessing a unique cellulase for digesting wooden debris buried in the deepest seafloor. [PDF]

PLoS ONE, 2012
The Challenger Deep in the Mariana Trench is the deepest point in the ocean (10,994 m). Certain deep-sea animals can withstand the extreme pressure at this great depth. The amphipod Hirondellea gigas is a resident of the Challenger Deep.
