N1 - Funding Information:
We thank IODP, CDEX, JAMSTEC, MWJ, and MQJ for generously providing logistical and financial support for the CLSI@Sea workshop and event attendees. We thank all the mentors for their support, their availability resulting in constructive discussions during the workshop. A special mention is for Gaku Kimura, at the origin of the idea of this workshop.We acknowledge the staff from JAMSTEC, Sean Tockzo, Lena Maeda, Yukari Kido, and Yoshinori Sanada, for the logistic organization of the workshop and their valuable advice onboard Chikyu. We also thank the Expedition 380 science party for their good mood and their availability to discuss and present their tasks, despite the incredible amount of work they had to manage. The whole crew and staff of D/V Chikyu, from the sailors to the stewards, the kitchen staff and the laboratory staff, and all the other teams we cannot list here, deserve special thanks for their hospitality and for doing a superb job, taking care of the workshop participants, and providing them with a fantastic environment to focus only on scientific questions. Finally, thanks go to all workshop attendees and participating scientists for their motivation and enthusiastic contributions, during and after the event, thereby helping to develop this report as a first concrete outcome from the CLSI@Sea workshop. All investigators, workshop attendees, the Exp. 380 Science party and daily reports can be found on the NanTroSEIZE Expedition 380 project website at https: //www.jamstec.go.jp/chikyu/e/nantroseize/expedition_380.html (last access: 22 September 2018).

N2 - The first International Ocean Discovery Program (IODP) Core-Log-Seismic Integration at Sea (CLSI@Sea) workshop, held in January-February 2018, brought together an international, multidisciplinary team of 14 early-career scientists and a group of scientific mentors specialized in subduction zone processes at the Nankai Trough, one of the Earth's most active plate-subduction zones located off the southwestern coast of Japan. The goal of the workshop was to leverage existing core, log, and seismic data previously acquired during the IODP's Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE), to address the role of the deformation front of the Nankai accretionary prism in tsunamigenic earthquakes and slow slip in the shallow portion of the subduction interface. The CLSI@Sea workshop was organized onboard the D/V Chikyu concurrently with IODP Expedition 380, allowing workshop participants to interact with expedition scientists installing a longterm borehole monitoring system (LTBMS) at a site where the workshop's research was focused. Sedimentary cores from across the deformation front were brought onboard Chikyu, where they were made available for new description, sampling, and analysis. Logging data, drilling parameters, and seismic data were also available for investigation by workshop participants, who were granted access to Chikyu laboratory facilities and software to perform analyses at sea. Multi-thematic presentations facilitated knowledge transfer between the participants across field areas, and highlighted the value of multi-disciplinary collaboration that integrates processes across different spatiotemporal scales. The workshop resulted in the synthesis of existing geophysical, geologic, and geochemical data spanning IODP Sites C0006, C0007, C0011 and C0012 in the NanTroSEIZE area, the identification of key outstanding research questions in the field of shallow subduction zone seismogenesis, and fostered collaborative and individual research plans integrating new data analysis techniques and multidisciplinary approaches.
