BOSEMENA: Borehole- and Sediment physical properties Measurements in the Nankai Accretionary complex, Japan

南开槽孕震区实验是一个研究俯冲带动力学直至孕震区的多科考IODP项目。虽然大量的巡航跨越了进入的板块、棱柱的脚趾和斜坡以及中央前弧（熊野盆地），主要目的是取芯沉积物和断层，但Exp332于2010年开始在两个地点部署钻孔观测站（Kopf et al., 2011）。它们都成功获取了数据，其中一个- GeniusPlug -在Exp365（2016年3月/ 4月）期间被恢复用于数据下载（Kopf等人，正在准备中）。在这两次航行中，这位倡议者都是CHIKYU的联合首席科学家，并在Exp365期间由不莱梅大学的一名硕士学生陪同（a . Rösner）。由于GeniusPlug的回收效率高，并且在C0010A井眼中无缝安装了CORK系统，因此在Exp365期间有充足的时间钻更多的井眼，在该地点回收了近100米的岩心。回收的物质主要来自上盘、断裂带和下盘到展斜断层。由于船上的科学小组只由地球物理学家和天文台专家组成，所以这些岩心在CHIKYU上一直没有打开，等待2016年8月Exp365期间的分裂、描述和后续分析。A. Rösner受邀作为物理属性专家参与Exp365的第二部分。在BOSEMENA项目中，我们提出了一个短期（3个月）的资助期，以解决三个关键任务，作为Exp365科学研究的一部分：(1)测量Exp365期间回收的所有核心材料的沉积物物理性质，如水分和密度，剪切强度和导热性。这些数据将补充和帮助评估观测数据，并将在Exp365的第二部分（2016年8月）期间在日本的CHIKYU上获得。(2)为《Exp365论文集》卷创建数据图并编写相关物理性质章节（方法、结果、初步解释）。(3)写一章关于GeniusPlug临时天文台的初步结果，该天文台在Exp365的第一部分中成功恢复，并承载了5年半的物理数据。与Kopf et al. （2011b）类似，这一章也将是论文集的关键部分。对于这三个任务中的每一个，我们都保留了appx。一个月。

NanTroSEIZE (Nankai Trough Seismogenic Zone Experiment) is a multi-expedition IODP project that studies subduction zone dynamics down to the seismogenic zone. While the wealth of the cruises, which span the incoming plate, toe and slope of the prism and central forearc (Kumano Basin) and mainly aim at coring sediments and faults, Exp332 set out to deploy borehole observatories at two sites in 2010 (Kopf et al., 2011a). Both of them acquired data successfully, and one of them - the GeniusPlug - was recovered during Exp365 (March/April 2016) for data download (Kopf et al., in prep.). The proponent served as co-chief scientist onboard CHIKYU for both of these cruises, and was accompanied during Exp365 by a Univ. Bremen Master student (A. Rösner).As a consequence of the time efficient recovery of the GeniusPlug and the seamless installation of a CORK system in the C0010A borehole there was ample time during Exp365 to drill additional holes that recovered close to 100m of core at this site. The material recovered originated from the hangingwall, fault zone and footwall to the splay fault. Since the onboard science party comprised solely geophysicists and observatory specialists, the cores remained unopened on board CHIKYU and await splitting, description and subsequent analyses in August 2016 during Exp365. A. Rösner is invited to participate into the second part of Exp365 as physical properties specialist.In the BOSEMENA project we propose for a short (3 months) funding period to tackle three key tasks as part of the Exp365 scientific research: (1) Measurement of sediment physical properties such as moisture and density, shear strength and thermal conductivity on all core materials recovered during Exp365. These data will complement and help evaluate the observatory data and will be acquired on board CHIKYU in Japan during part 2 of Exp365 (August 2016). (2) Create data plots and write the relevant Physical properties chapters (Methods, Results, Initial interpretation) for the Exp365 Proceedings volume. (3) Write a chapter on the first results of the GeniusPlug temporary observatory, which was recovered successfully during part 1 of Exp365 and which hosted 5 ½ years worth of physical data. In analogy to Kopf et al. (2011b), such a chapter will also be a crucial part of the proceedings volume. For each of the three tasks we have reserved appx. one month.
