VISUALIZATION OF THE GEOPHYSICAL SETTINGS IN THE PHILIPPINE SEA MARGINS BY MEANS OF GMT AND ISC DATA [PDF]
Central European Journal of Geography and Sustainable Development, 2020 The presented research aimed to perform geophysical modelling (gravity and geoid) and to evaluate the spatio-temporal variation of the marine geological data (distribution and depth of earthquakes) using combination of the Generic Mapping Tools (GMT ...

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.

Obligately barophilic bacterium from the Mariana trench. [PDF]
Proceedings of the National Academy of Sciences, 1981 An amphipod (Hirondellea gigas) was retrieved with decompression in an insulated trap from an ocean depth of 10,476 m. Bacterial isolates were obtained from the dead and cold animal by using silica gel medium incubated at 1000 bars (1 bar = 10(5) Pa) and 2 degrees C.

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

Distinctive signatures of pathogenic and antibiotic resistant potentials in the hadal microbiome
Environmental Microbiome, 2022 Background Hadal zone of the deep-sea trenches accommodates microbial life under extreme energy limitations and environmental conditions, such as low temperature, high pressure, and low organic matter down to 11,000 m below sea level.

Tidal turbulence in deep Mariana Trench waters?
, 2023 To study potential turbulent water motions near the deepest point on Earth in the Challenger Deep of the Mariana Trench, a 588-m long string equipped with specially designed sensitive temperature sensors was moored for nearly three years in 10.9 km water depth.

Microbial Community Diversity Within Sediments from Two Geographically Separated Hadal Trenches
Frontiers in Microbiology, 2019 Hadal ocean sediments, found at sites deeper than 6,000 m water depth, are thought to contain microbial communities distinct from those at shallower depths due to high hydrostatic pressures and higher abundances of organic matter.

Microplastics and synthetic particles ingested by deep-sea amphipods in six of the deepest marine ecosystems on Earth [PDF]
Royal Society Open Science, 2019 While there is now an established recognition of microplastic pollution in the oceans, and the detrimental effects this may have on marine animals, the ocean depth at which such contamination is ingested by organisms has still not been established. Here,
