Phytoplankton-derived polysaccharides and microbial peptidoglycans are key nutrients for deep-sea microbes in the Mariana Trench. [PDF]
MicrobiomeBackground The deep sea represents the largest marine ecosystem, driving global-scale biogeochemical cycles. Microorganisms are the most abundant biological entities and play a vital role in the cycling of organic matter in such ecosystems.

High hydrostatic pressure shapes the development and production of secondary metabolites of Mariana Trench sediment fungi. [PDF]
Sci Rep, 2021 The hadal biosphere is one of the least understood ecosystems on our planet. Recent studies have revealed diverse and active communities of prokaryotes in hadal sediment. However, there have been few studies on fungi in hadal sediment. Here we report the

Insight Into the Pico- and Nano-Phytoplankton Communities in the Deepest Biosphere, the Mariana Trench. [PDF]
Front Microbiol, 2018 As photoautotrophs, phytoplankton are generally present in the euphotic zone of the ocean, however, recently healthy phytoplankton cells were found to be also ubiquitous in the dark deep sea, i.e., at water depths between 2000 and 4000 m.

Modulation of intra-oceanic trench bending and along-trench thermochemical transport by mantle toroidal flow. [PDF]
Nat CommunOceanic trench bending over 1000 km occurs globally, with notable along-trench variations in mantle wedge thermochemistry. However, the mechanisms influencing both shallow trench geometry and deep mantle state remain unclear. Here we focus on the Mariana

Flow Pathways of Abyssal Water in the Yap Trench and Adjacent Channels and Basins
Frontiers in Marine Science, 2022 Abyssal flow pathways in the Yap Trench and adjacent regions were investigated by computing geostrophic flows and analyzing water properties. Using boundary values of potential temperature, salinity, oxygen, and silicate, the upper and lower Circumpolar ...

Upper Mantle Structure Beneath Mariana: Insights From Rayleigh‐Wave Anisotropic Tomography
Geochemistry, Geophysics, Geosystems, 2021 We determine Rayleigh‐wave phase‐velocity azimuthal anisotropy tomography beneath Mariana using a large number of high‐quality amplitude and phase data of teleseismic fundamental mode Rayleigh waves at periods of 25–130 s.

Slab Pull Drives IBM Trench Advance Despite the Weakened Philippine Sea Plate
Geophysical Research Letters, 2023 The mechanism behind the significant Izu‐Bonin‐Mariana (IBM) trench advance is still controversial. We conduct slab subduction numerical models that reproduce the spatio‐temporal tectonic evolution of the Philippine Sea region to investigate whether slab
