Importance of pumiceous sediment in influencing chemistry of hydrothermal fluids in Okinawa Trough: insights from boron isotopic ratios

Progress in Earth and Planetary Science
The involvement of sediments in the Okinawa Trough hydrothermal system is well-established. However, data on boron in sediments are scarce, with minimal quantitative analysis.

Inversion of Induced Polarization Parameters From Time‐Domain Electromagnetic Data Using the Debye Decomposition Model

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Time‐domain electromagnetics (TEM) is a valuable tool for exploring seafloor hydrothermal deposits, which are characterized by variations in resistivity and chargeability. Several surveys using the Waseda integrated seafloor time‐domain electromagnetics (WISTEM) have been conducted.

Organic carbon burial and their implication on sea surface primary productivity in the middle Okinawa Trough over the past 200 ka

Frontiers in Marine Science
The long-term burial of organic carbon in marginal seas plays a critical role in Earth’s carbon cycle and climate change. However, the mechanism of organic carbon (OC) burial in the Okinawa Trough (OT) during glacial-interglacial timescales remains ...

Active Rift System in the Okinawa Trough and Its Northeastern Continuation [PDF]

, 1996
Recent submarine, geological and geophysical investigations have revealed that the present central rift system of the Okinawa Trough which is an active extensional axis of the trough has been formed since about 2 Ma. Two stages of the formation processes

The Relation Between Two Types of Frequent Wave Breaking Over Southeastern Siberia and Different Conditions of Unseasonable Midsummer Weather Over Japan

International Journal of Climatology, Volume 46, Issue 10, August 2026.
To analyze the different morphologies of Rossby wave breaking over Eastern Siberia and their relationships with the anomalous patterns of temperature and precipitation that cause unseasonable midsummer weather conditions over Japan, we performed regression analyses against the interannual variabilities of the anticyclonic and cyclonic Rossby wave ...

Energetic Comparison of Linear Fresnel and Parabolic Trough Collector Systems [PDF]

, 2012
Within the last years, Linear Fresnel (LF) collector systems have been developed as a technical alternative to parabolic trough collector (PT) systems. In the past, LF systems focused on low- and medium temperature applications.

Seismic Constraints on Igneous Intrusions and Fluid/Gas Distribution in a Continental Back‐Arc System: Evidence From the Yaeyama Rift in the Southern Okinawa Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The geometry and distribution of igneous intrusions, which define melt source locations and record syn‐emplacement stress conditions, are essential for understanding tectonic and magmatic processes associated with crustal extension. However, in back‐arc settings along continental margins, structural constraints on these features remain poorly ...

Origins of magmatism in the Okinawa Trough: Fe–Sr–Nd–Pb–Hf isotopic constraints

, 2023
The Okinawa Trough is an incipient back-arc basin formed by the subduction of the Philippine Sea Plate beneath the Eurasian Plate and is a natural laboratory for studying basin evolution, magmatism, and crust-mantle interactions during the early stages ...
