[SSS04-13] Recall the past to address future scientific challenges from legacy data to advance understanding of seisimogenic subduction zone: An IODP workshop Core-Log-Seismic investigation at Sea
Keywords:Core-Log-Seismic Investigation at Sea, Nankai Trough
The singularity of CLSI@Sea workshop lies in the fact that expedition 380 aimed to install a new LTBSMS in toe of the prism, while the CLSI@Sea participants were revisiting the legacy data acquired at the same site during previous expeditions. The well-preserved cores drilled 10 years ago were specially stored on board Chikyu and available for new sampling and analysis, demonstrating the value of archived data. The goal was to develop discussions about integrative and interdisciplinary research to address outstanding questions regarding the processes at the origin of tsunamigenic- and slow earthquakes in subduction zones, crucial topics for the regional tectonics, but also fundamental aspects of the Earth’s geodynamic.
A challenging aspect of CLSI@Sea was to connect together expert mentors scientists in subducting margin with 14 early career workshop participants from different backgrounds, to work on common scientific questions. The multi-thematic debates organised during CLSI@Sea successfully resulted in a transfer of knowledge between both parties, highlighting the value of multi-disciplinary collaboration in parallel of individual research activities, as well as the importance to quantify interactive scientific processes from different spatiotemporal scales. Lively discussions in a cordial atmosphere, and teamwork between mentors, participants and IODP staff in the Chikyu focused environment, were key components to the synthesis of crucial research questions and efficient development of both individual and collective research, and publication plans.
This talk will summarize the workshop and present the ongoing new researches organized by CLSI@Sea participants during workshop 380.
