Wed. May 25, 2016 3:30 PM - 5:00 PM 102 (1F)

Convener:*Tetsuo Ohata(Arctic Environment Research Center, National Institute of Polar Research), Masahiro Hori(Earth Observation Reseacrh Center, Japan Aerospace Exploration Agency), kazuyoshi suzuki(Japan Agency for Marine-Earth Science and Technology), Shin Sugiyama(Institute of Low Temperature Science, Hokkaido University), Chair:Masahiro Hori(Earth Observation Reseacrh Center, Japan Aerospace Exploration Agency)

The cryosphere is one fundamental component of earth system. It is a region where snow and ice, in the form of glacier/ice sheet, snow cover and snowfall, frozen ground, sea ice and fresh water ice exist, and they interact with other components such as atmosphere, ocean, ecosystem and others. In this session, research results on physical and chemical characteristics of snow and ice, their variation and dynamics, their role in the earth, and also in other planets will be discussed widely, regardless of the research method.
