    Geometric barriers impacted rupture processes and stress releases of the 2023 Kahramanmaraş, Türkiye, earthquake doublet by Jiangcheng Zhou, Yueyi Xu, Yong Zhang, Wanpeng Feng, Tuncay Taymaz, Yun-Tai Chen, Chenyu Xu, Beibei Xu, Rongjiang Wang, Fuqiang Shi, Zhigang Shao, Qinghua Huang

    Published 2025-01-01
    “…We speculate that the geometric barriers of the first event hindered the stress release, leading to rupture of more small asperities and generation of high-frequency signals. In contrast, the simpler fault geometry of the second event facilitates a larger stress drop and a more complete stress release.…”

    Variability of nutrient transport and associated upper ocean primary production induced by Kuroshio meanders in the Enshu-nada Sea, Japan by Namazue Gaku, Uchiyama Yusuke, Zhang Xu, Masunaga Eiji

    Published 2025-01-01
    “…The upper ocean nitrate flux budget analysis showed that the subsurface nitrate was transported upward as a vertical diffusive flux around the north (shoreward) of the Kuroshio path and as a mean vertical advective flux in the Kuroshio downstream region around the Izu-Ogasawara Ridge. In contrast, high-frequency eddy vertical advective fluxes caused downward transport, but to a degree about 20% smaller than the other fluxes. …”
