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 ...

Detrital zircon U-Pb geochronology of sediments from the Okinawa Trough: implications for sedimentary provenance

Frontiers in Earth Science
In order to distinguish terrestrial material sources in the Okinawa Trough (OT), this study analyzed four surface sediment samples from the northern, middle, and southern parts of the OT using detrital zircon U-Pb age analysis.

A Decade of Global Navigation Satellite System/Acoustic Measurements of Back-Arc Spreading in the Southwestern Okinawa Trough

Frontiers in Earth Science, 2021
Long-term seafloor geodetic measurements are important for constraining submarine crustal deformation near plate boundaries. Here we present an integrated analysis of a decade of GNSS/acoustic data collected at a site 60 km to the east of northeast ...

Ancestral Biogeography Reveals Diverse Origins of Costa Rica Margin Seep Invertebrates

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim This work addressed the hypotheses that invertebrate species from hydrocarbon seeps at the Pacific Costa Rica Margin (CRM) would descend from adjacent biogeographic provinces, and that common ancestral histories would be identified across invertebrate groups.

Benthoplanidae, a new family of benthic ctenophores (Platyctenida), based on morphological and genetic data

Journal of Systematics and Evolution, Volume 64, Issue 2, Page 387-400, March 2026.
The benthic ctenophore Benthoplana meteoris (adults left and bottom, planktonic juveniles to the top right), type species for the genus, which in turn is type for the newly erected family: Benthoplanidae (Ctenophora, Platyctenida). Abstract We present a phylogenetic analysis of benthic ctenophores of the order Platyctenida, sampling all but one genus ...

Large-scale slope failure and active erosion occurring in the southwest Ryukyu fore-arc area [PDF]

, 2001
The southwestern Ryukyu area east of Taiwan Island is an arcuate boundary between Philippine Sea Plate and Eurasian Plate. The topographic features in the area are characterised by (1) a large-scale amphitheatre off Ishigaki Island, just on the ...

Marine Heatwaves, Ocean Warming and Acidification Reshape Reef Fish Gut Microbiomes

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Extreme climatic events and gradual climate change are increasingly anticipated to interact and reshape ecological communities. However, the combined effects of ocean warming, acidification and marine heatwaves on host‐associated microbial communities and their potential role in host adaptation remain poorly understood.
