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 ...

Development of a Hadal Microbial In Situ Multi-Stage Filtering and Preserving Device

Journal of Marine Science and Engineering, 2021
The unique environment of the hadal zone has created material circulation patterns and biological gene characteristics. Microbes play an irreplaceable role in the ocean ecological environment and material circulation due to their pervasiveness, abundance,

Construction of High-Resolution Bathymetric Dataset for the Mariana Trench

IEEE Access, 2019
Access to reliable and accurate bathymetric data is fundamental to many marine activities. This paper proposes a merge-normalization (MN) method that is suitable for multisource bathymetric data fusion in deep ocean areas, to solve the problem of ...

Development of Single-Nucleotide Polymorphism Markers and Population Genetic Analysis of the Hadal Amphipod Alicella gigantea across the Mariana and New Britain Trenches

Journal of Marine Science and Engineering
Alicella gigantea, the largest amphipod scavengers found to date, play key roles in the food web of the hadal ecosystem. However, the genetic structure of A. gigantea populations among different trenches has not been reported yet.

Identification of Free-living and Particle-Associated Microbial Communities Present in Hadal regions of the Mariana Trench

Frontiers in Microbiology, 2016
Relatively few studies have described the microbial populations present in ultra-deep hadal environments, largely as a result of difficulties associated with sampling. Here we report Illumina-tag V6 16S rRNA sequence-based analyses of the free-living and

An Empirical Study of R Applications for Data Analysis in Marine Geology

Marine Science and Technology Bulletin, 2019
The study focuses on the application of R programming language towards marine geological research with a case study of Mariana Trench. Due to its logical and straightforward syntax, multi–functional standard libraries, R is especially attractive to the ...

Segmentation of the Izu-Bonin and Mariana slabs based on the analysis of the Benioff seismicity distribution and regional tomography results [PDF]

Solid Earth, 2013
We present a new model of P and S velocity anomalies in the mantle down to a depth of 1300 km beneath the Izu-Bonin and Mariana (IBM) arcs. This model is derived based on tomographic inversion of global travel time data from the revised ISC catalogue ...

Computing and Plotting Correlograms by Python and R Libraries for Correlation Analysis of the Environmental Data in Marine Geomorphology

Jeomorfolojik Araştırmalar Dergisi, 2019
The geomorphology of the Mariana Trench, the deepest ocean trench on the Earth, has a complex character: its transverse profile is asymmetric, the slopes are higher on the side of the Mariana island arc.

Bacteria are important dimethylsulfoniopropionate producers in marine aphotic and high-pressure environments

Nature Communications, 2020
Dimethylsulfoniopropionate (DMSP) is an osmolyte produced by marine microbes that plays an important role in nutrient cycling and atmospheric chemistry.

Inferring the Paleo‐Location of Proto‐Arc Magmas During Subduction Infancy in the Izu‐Bonin‐Mariana

Geochemistry, Geophysics, Geosystems
Subduction zones are one of the principal drivers of the modern‐day plate tectonics, but the processes that develop as incipient subduction zones mature are yet to be understood.
