[A-CC32] Glaciology

Wed. May 28, 2025 1:45 PM - 3:15 PM Exhibition Hall Special Setting (4) (Exhibition Hall 7&8, Makuhari Messe)

convener:Yukihiko Onuma(Japan Aerospace Exploration Agency), Tomonori Tanikawa(Meteorological Research Institute, Japan Meteorological Agency), Tatsuya Watanabe(Kitami Institute of Technology), Shuntaro Hata(Geoscience Group, National Institute of Polar Research), Chairperson:Yukihiko Onuma(Japan Aerospace Exploration Agency)

The cryosphere is a fundamental component of the earth system. It is a region where snow and ice exist in the form of glacier/ice sheet, snow cover and snowfall, frozen ground, sea ice and fresh water ice, and they play a critical role in the global environment under the interactions with atmosphere, ocean, ecosystem and others. In this session, research results on physical and chemical characteristics of snow and ice, variations and dynamics of cryospheric environment, roles of the cryosphere on the earth and other planets will be discussed broadly, regardless of the research method.
