This is the final year of the five years research project, "Giant reservoirs of heat/water/material: Global environmental changes driven by Southern Ocean and Antarctic Ice Sheet", which has been started in July 2017and funded by JSPS (Japan Society for the Promotion of Science). The project is aiming to establish a new research area for Antarctic environmental system science. The project consists of 7 research topics, including Antarctic ice sheet and Southern ocean sciences, new observation methodology, modeling and other interdisciplinary topics, and we are involved in the topic, "Interaction of the solid Earth and the Antarctic Ice Sheet".
Thus far, we have been conducting several field surveys in Antarctica, e.g., absolute gravity measurements, GNSS measurements, lake sediment coring, topographic surveys, geomorphological and other surveys near Japanese Syowa station and other foreign research stations as well. In parallel with these observations, we also have been conducting GIA model analyses, satellite data analyses, and ground data analyses. These results have been reported at the previous JpGU meetings and other opportunities.
The year 2020 and 2021 activities were unfortunately quite limited due to the COVID-19 pandemic. Most of field surveys were cancelled, and there were a lot of inconveniences to conduct the research works. While some of the research activities will be continued in 2022 financial year to recover the delays due to the COVID-19 pandemic, we report the summary of the 5 years activities and the results in this presentation.
This study was partially supported by JSPS KAKENHI Grant No. 17H06321.
