To reconstruct past climate and environmental changes, I promote ice core study using samples obtained from the Antarctic and Greenland ice sheets. Recently, I have been focusing on the gas components of ice cores, analyzing isotopic compositions of the air, such as nitrogen, oxygen, and argon, as well as greenhouse gas concentrations and isotopic compositions of noble gases. Using these data, I try to construct the age scale of the ice cores and reconstruct the surface environment of the Antarctic ice sheet, including temperature, accumulation rates, ice thickness, firn thickness, and so on. In addition, I am setting up a new laboratory for measuring CO2 concentrations from the coming oldest ice core.
Field experience:
Jun - July 2018 The East Greenland Ice-core Project (EGRIP) (Logging and processing)
Oct. 2017 - Feb. 2018 59th Japanese Antarctic Research Expedition (summer, Dome Fuji traverse)
May 2015 Greenland South East Dome (SE Dome) shallow ice core drilling
