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

NantroSEIZE（南开海槽地震带实验）是一个多考察IODP项目，研究俯冲带动力学下至地震带。虽然巡航的财富，跨越传入板，脚趾和斜坡的棱柱和中央前弧（熊野盆地），主要目的是取芯沉积物和断层，Exp 332开始部署钻孔观测站在两个地点在2010年（Kopf等人，2011年a）。他们都成功地获取了数据，其中一个-GeniusPlug -在Exp 365（2016年3月/4月）期间恢复用于数据下载（Kopf等人，正在编写中）。这两次航行的共同首席科学家都是由这位提议者担任的，在Exp 365期间，一位不莱梅大学的硕士生（A。由于GeniusPlug的高效回收和COLK系统在C 0010 A钻孔中的无缝安装，Exp 365期间有充足的时间在该现场钻取了近100米的岩心。采出物主要来源于上盘、断裂带和下盘至展布断层。由于船上的科学团队仅由地球物理学家和天文台专家组成，因此这些岩心在CHIKYU上仍未开封，并等待2016年8月Exp 365期间的分裂，描述和后续分析。A. Rösner被邀请作为物理特性专家参与Exp 365的第二部分。在BOSEMENA项目中，我们建议在短期（3个月）内完成Exp 365科学研究的三项关键任务：（1）测量Exp 365期间回收的所有岩心材料的沉积物物理特性，如水分和密度，剪切强度和热导率。这些数据将补充和帮助评估观测数据，并将在Exp 365第2部分（2016年8月）期间在日本的CHIKYU上获得。(2)为Exp 365 Proceedings卷创建数据图并编写相关的物理性质章节（方法，结果，初始解释）。(3)写一章关于GeniusPlug临时天文台的第一个结果，该天文台在Exp 365的第一部分成功恢复，并保存了5年半的物理数据。与Kopf等人（2011年b）类似，这一章也将是会议记录卷的关键部分。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.
