In-situ continuous observations of atmospheric O2/N2 ratio and CO2 concentration on-board "SHIRASE" in the Southern Ocean

Atmospheric O2/N2 ratio and CO2 concentration had been observed continuously on-board the icebreaker "SHIRASE" from Fremantle, Australia to Syowa Station, and from Syowa Station to Sydney, Australia.大气氧氮比（Atmospheric O2/N2 ratio）与二氧化碳浓度（CO2 concentration）已在‘白濑’号（SHIRASE）破冰船上被连续观测，观测航线涵盖从澳大利亚弗里曼特尔至昭和基地（Syowa Station），以及从昭和基地至澳大利亚悉尼两段航程。
