[M-TT49] GEOSCIENTIFIC APPLICATIONS OF HIGH-DEFINITION TOPOGRAPHY AND GEOPHYSICAL DATA IN THE ANTHROPOCENE

convener:Yuichi S. Hayakawa(Faculty of Environmental Earth Science, Hokkaido University), Shigekazu Kusumoto(Graduate School of Science and Engineering for Research, University of Toyama), Christopher A Gomez(Kobe University Faculty of Maritime Sciences Volcanic Risk at Sea Research Group)

Recent technical developments have enabled us to acquire high-definition topographic and geophysical data for geoscientific research, including land surface processes, subsurface structures, submarine and aerial environments, and geo-ecological interactions. Such high-definition or high-resolution data are particularly useful for studies on relatively short-term, i.e., decadal to millennial time scales, and for future predictions using numerical modelings. In this session, we expect submissions on topics challenging the issues in the Anthropocene, the most recent geological era of the Earth considerably affected by human activities. A range of topics would fit the session framework, such as theoretical works, improvements in the data acquisition, extensive data preservation and archiving, pre- and post-processing, statistical analysis, physical modeling, and numerical simulation for any kind of geoscientific research in the Anthropocene. The methodological approaches may include, but not limited to, laser scanning, SfM-MVS photogrammetry, GNSS precise positioning, SAR interferometry, multi-beam sonar, ground-penetrating radar, geomagnetic and electromagnetic sensors, based on terrestrial (fixed or mobile) and aerial (UAV or manned airborne) platforms.
