Distribution and Discharge of Dissolved Methane in the Middle Okinawa Trough, East China Sea
Frontiers in Earth Science, 2020 Widespread seepage of methane from seafloor sediments on continental margins are released into seawater, a portion of which may escape to the atmosphere.

Metabolically active microbial communities in marine sediment under high-CO2 and low-pH extremes [PDF]
, 2012 Sediment-hosting hydrothermal systems in the Okinawa Trough maintain a large amount of liquid, supercritical and hydrate phases of CO2 in the seabed. The emission of CO2 may critically impact the geochemical, geophysical and ecological characteristics of

Effect of Submerged Vegetation on Water Surface Geometry and Air–Water Momentum Transfer
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying its impact on the equivalent aerodynamic roughness of the water surface is essential for improved boundary‐layer parameterization in oceanic and atmospheric models. In

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Dissolved neodymium (Nd) isotopes are key tracers for water mass mixing in the open ocean and for land‐ocean exchanges in marginal seas. Hydrogenous Nd isotope ratios (expressed as εNd) in cores north of the equator reflect values of the surrounding lithology and tend to vary in accordance with local rainfall records, indicating higher ...

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

Review of Methane Seepages in the Okinawa Trough: Progress and Outlook
Geofluids, 2021 It has been two decades since the cold seeps were firstly found in the Okinawa Trough (OT). The scientific cruises and the geological surveys since then have unveiled the currently active submarine methane seeps and significantly improved the ...

Geochemical evidence for hydrothermal activity in the Okinawa trough.
GEOCHEMICAL JOURNAL, 1988 A distinct hydrothermal plume was found in the Iheya Graben in the middle Okinawa Trough in May, 1987, by using methane, manganese and the helium isotope ratio (3He/4He) as the geochemical tracers. The plume rises to an altitude of about 300-400 m above the sea floor with maximum methane and manganese anomalies of up to 650 nl kg-1, and 0.54μg kg-1 ...
