This projext funds the PIs propose retrieve four Chemical and Aqueous Transport (CAT) apparatuses that were deployed in May 2006 in conjunction with a JAMSTEC Shinkai 6500 dive program in the Kumano basin. The objective is to monitor fluid seeps from out-of-sequence thrusts (OOSTs) near the NANTROSEIZE drilling area (SW Japan), and the frontal thrust region. The instruments were originally deployed with funding from an ODP SGER grant, which was essential to take advantage of the "free"JAMSTEC ship and submersible time.This work is intended as a pilot study that will allow the PIs to begin to understand how the seeps in the Nankai region behave and what opportunities and problems may arise as they plan for future work in this region. A Japanese Shinkai 6500 dive proposal has been approved for dives in 2007. This work will allow the PIs to do the analysis of the data in order to determine the basic activity and chemistry of the seeps in this region and redeploy new instruments to maintain observation continuity.The broader impacts of this project include the training of a graduate student, who will have responsibility for analysis of the samples. The project will support increased international collaboration with Japanese researchers. The data will also provide a signification contribution to the greater science community studying subduction processes at Nankai, a MARGINS focus site. The project has significant societal relevance as well, since one of the aspects of the Nankai research is the generation of large earthquakes and tsunamis.

该项目资助了 PI 提议回收 2006 年 5 月与熊野盆地 JAMSTEC Shinkai 6500 潜水计划一起部署的四台化学和水传输 (CAT) 设备。 目的是监测 NANTROSEIZE 钻探区域（日本西南部）和锋面逆冲区域附近的无序逆冲 (OOST) 的流体渗漏。 这些仪器最初是在 ODP SGER 赠款的资助下部署的，这对于利用“免费”JAMSTEC 船舶和潜水时间至关重要。这项工作旨在作为一项试点研究，让 PI 开始了解渗漏的方式他们在规划南开地区未来工作时可能会遇到哪些机遇和问题。日本 Shinkai 6500 潜水提案已获批准在 2007 年进行潜水。这项工作将使 PI 能够对数据进行分析，以确定该地区渗透物的基本活动和化学成分，并重新部署新仪器以保持观测的连续性该项目更广泛的影响包括培训一名负责样本分析的研究生。 该项目将支持加强与日本研究人员的国际合作。 这些数据还将为 MARGINS 重点站点南开研究俯冲过程的更大科学界做出重大贡献。 该项目也具有重要的社会意义，因为南开大学研究的内容之一是大地震和海啸的产生。
