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

open access: yesJournal 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 ...

Een archeologische begeleiding van de reconstructie van de kruising N34 Hardenberg-De Punt aansluiting Gasselte te Gasselte, gemeente Aa en Hunze (Dr.): ARC-Rapporten 2008-69

open access: yes, 2009
Bij de begeleiding is gebleken dat de bodem op het onderzoeksterrein in recente tijden dusdanig bewerkt is ten behoeve van landbouwdoeleinden en infrastructurele werken, dat van een archeologisch bodemarchief (als dit ooit aanwezig is geweest) geen ...

Phylogenetic diversity and comparative historical demography within a species complex of Indo-West Pacific Saccostrea oysters

open access: yesAquatic Living Resources
Taxonomic uncertainties, often arising from cryptic species or lineages, present a significant impediment to wildlife conservation. This problem has been partially alleviated by the advent of DNA barcoding.

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 Lg-wave attenuation tomography: Method, algorithm, data processing flow and application

open access: yes地球与行星物理论评, 2022
With the rapid development of modern seismic network, seismological signals can be digitally recorded in broad frequency band, larger dynamic range, and higher spatial density, which provide the possibility of obtaining fine structures of the quality ...

Male Dimorphism in a New Species of Cockroach Nocticola glenniei sp. nov. (Blattodea: Nocticolidae) Commensal Within Burrows of Macropanesthia rhinoceros Saussure, 1895 (Blattodea: Blaberidae)

open access: yesAustral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Polyphenism, where individuals of the same species exhibit distinct physical or behavioural forms, is widespread across insects. Although well studied in charismatic beetles and eusocial insects such as termites and bees, only a few minor cases of male dimorphism have been reported in non‐termite cockroaches. Here, we describe a new species of

Een archeologisch bureau-onderzoek en verkennend inventariserend veldonderzoek door middel van boringen voor een terrein op Provincialeweg 22 te Sint Maartensdijk, gemeente Tholen (Z): ARC-Rapporten 2011-85

open access: yes, 2011
De onderzoekslocatie ligt in het buitengebied ten oosten van Sint Maartensdijk op een getij-oeverwal van de Pluimpot. Door de ligging op de getij-oeverwal heeft de onderzoekslocatie een middelhoge trefkans op archeologische resten vanaf de Vroege ...

Highlands, Islands and the Evolutionary Impact of Founder Event Dispersal in Sinomicrurus Coralsnakes

open access: yesJournal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Island archipelagos and montane regions of East and Southeast Asia represent some of the world's most biodiverse yet poorly understood biogeographic systems. Whether regional diversity accumulates primarily through in situ speciation, dispersal‐mediated range shifts, or some combination of these processes remains unclear.

Magmatism and tectonism in the Ryukyu Arc and Okinawa Trough revealed by the Japan Coast Guard’s AUV high-resolution mapping.

open access: yes, 2021
The Ryukyu subduction zone in the Western Pacific, extending from Japan to Taiwan, forms a typical trench (Ryukyu Trench)-arc (Ryukyu Arc)-back-arc basin (Okinawa Trough) system.

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 ...
