Detrital Zircon Provenance in the Sediments in the Southern Okinawa Trough

open access: yesJournal of Marine Science and Engineering, 2022
The provenance of sediments in the Southern Okinawa Trough since the late Holocene has been a controversial scientific issue during the past 20 years. Previous studies based on isotope proxies generally indicated Taiwanese rivers as the primary source in

Understanding the Compositional Variability of the Major Components of Hydrothermal Plumes in the Okinawa Trough

open access: yesGeofluids, 2018
Studies of the major components of hydrothermal plumes in seafloor hydrothermal fields are critical for an improved understanding of biogeochemical cycles and the large-scale distribution of elements in the submarine environment. The composition of major

Geochemistry and provenance of core sediments from the southwestern Okinawa Trough [PDF]

open access: yesOceanological and Hydrobiological Studies
Understanding the sedimentary processes and provenance in the Okinawa Trough is critical for reconstructing regional tectonic evolution and sediment transport dynamics in this active back-arc basin.

Distribution of b-value in the central and southern Ryukyu: is the low b-value in the rift-axis of the Okinawa Trough accurate?

open access: yesEarth, Planets and Space, 2022
Here, I investigated whether the b-value in the rift-axis of the Okinawa Trough, a back-arc basin, is low. The cause of the low b-value in the rift-axis of the Okinawa Trough had previously been interpreted as increased stress by dyke intrusion. However,

The Huapinghsu Channel/Mienhua Canyon System as a Sediment Conduit Transporting Sediments From Offshore North Taiwan to the Southern Okinawa Trough

open access: yesFrontiers in Earth Science, 2022
By examining bathymetric and seismic reflection data in the shelf-slope region offshore northeast of Taiwan, the morphology of the Huapinghsu Channel/Mienhua Canyon System was refined and the occurrence of axial incision in the major erosional trough of ...

Characteristics of seismicity in the southern Okinawa Trough and their relation to back-arc rifting processes

open access: yesEarth, Planets and Space, 2021
The southern part of the Okinawa Trough forms a narrow back-arc rift basin where evidence for submarine volcanoes and active hydrothermal venting is observed.

Seismic structure of rifting in the Okinawa Trough, an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench system

open access: yesEarth, Planets and Space, 2019
The Okinawa Trough, to the southwest of Kyusyu, Japan, is an active backarc basin of the Ryukyu (Nansei-Shoto) island arc–trench system caused by the Philippine Sea plate subduction. Unlike other backarc basins around Japan, the Okinawa Trough, ~ 1000 km

Variability of the Deep Overflow through the Kerama Gap Revealed by Observational Data and Global Ocean Reanalysis

open access: yesJournal of Marine Science and Engineering, 2020
Herein, the temporal variability of the deep overflow through the Kerama Gap between the East China Sea and the Philippine Sea is investigated based on observational data combined with reanalysis data obtained during 2004–2011. The observations and model

Characterization of water masses around the southern Ryukyu Islands based on isotopic compositions

open access: yesProgress in Earth and Planetary Science, 2022
We investigated the water-mass structure on the Okinawa Trough and Pacific sides of the southern Ryukyu Island Arc (Yonaguni, Iriomote, and Ishigaki subareas) using the Nd isotope composition (143Nd/144Nd ratios; expressed as εNd values) of benthic ...
