Hydrothermal Characteristics of the Mienhua Submarine Volcano in the Southernmost Okinawa Trough

Marine Geophysical Research, 2022
Abstract The Mienhua submarine volcano (MHV) is located in the southernmost Okinawa Trough and exhibits vigorous hydrothermal activity. This paper presents a detailed volcanic morphological analysis of the MHV, which has not been fully explored or discussed in terms of its hydrothermal characteristics and their relationship to hydrothermal ...

Holocene Climate Changes: Unraveling Processes, Mechanisms, and Impacts Across Spatiotemporal Scales

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract As the most recent interglacial period and the timeframe for the development of human civilization, the Holocene provides a critical perspective for understanding future climate under continued global warming. This special collection focuses on Holocene climate changes and features 14 interdisciplinary studies.

Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.

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.

Ambient Noise and Teleseismic Signals Recorded by Ocean-Bottom Seismometers Offshore Eastern Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2010
Broadband records from ocean-bottom seismometers deployed in the Okinawa trough and the Huatung basin were analyzed to provide seafloor noise characteristics and the detection thresholds for teleseismic body and surface waves. Ambient noise levels on the

A numerical study on the effects of a midlatitude upper-level trough on the track and intensity of Typhoon Bavi (2020)

Frontiers in Earth Science, 2023
The complex interactions between a tropical cyclone (TC) and the midlatitude upper-level trough or cutoff low (sometimes called a cold-core vortex) can lead to an unusual track, such as sudden turning motion, and intensity change of the tropical cyclone,

Evidence for the 8,200 a b.p. cooling event in the middle Okinawa Trough [PDF]

Geo-Marine Letters, 2007
Based on new and existing data on oxygen isotopes, alkenone-surface seawater temperature trends, planktonic foraminifers, lithology, and clay mineral composition of piston cores, a distinct cooling event has been identified around 8,200 cal a B.P. in the middle Okinawa Trough, northwest Pacific. This corresponds to the 8,200 a B.P.

Distant Storms Can Affect Seismic Noise Crustal Monitoring

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Using seismic noise interferometry to monitor the Earth's interior relies on continuous seismic wavefields produced by stable, invariant sources. In numerous applications, this condition is relaxed, arguing that secondary scattering effects render the late coda source independent.

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...
