Abstract 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 …

Abyssal flow pathways in the Yap Trench and adjacent regions were investigated by
computing geostrophic flows and analyzing water properties. Using boundary values of …

We examine baseline water properties and bottom water patterns in hadal trench
environments across the Southern Ocean, Indian Ocean, and western Pacific. Significant …

Uncovering the spatial distribution of deep-sea sediment lithologies is crucial for the
research on earth system science and the exploration of critical mineral resources. The …

Bottom circulation in the abyssal Caroline Sea is an important component of the global
meridional overturning circulation. By use of a high-resolution regional ocean model, the …

Ocean circulation in the Challenger Deep is rarely investigated due to sparse observations.
Based on hydrographic data collected by two super‐deep Chinese “Sea‐Wing” gliders …

Abstract 2, 4, 6-Tripyridine-s-triazine (TPTZ) spectrophotometric method was applied to
determine the concentrations of dissolved monosaccharides (MCHO), polysaccharides …

Abstract Methane (CH4) and dimethylsulphoniopropionate (DMSP) are major carbon and
sulfur sources for bacterioplankton in the ocean. We investigated the characteristics of CH4 …

The water column in the open ocean can be divided into epipelagic (photic), mesopelagic,
bathyal, abyssal and hadal zones by depth. In recent years, more and more research has …

The oceanic hadal zone, defined as regions where water depths are greater than 6,000 m, is
located mainly in subduction trenches, fracture zones and a few deep basins (Jamieson & …
