Symposium vol 1 "Grobal Warming -From the land to the Ocean-"


We hold the first COE Symposium on 25 April (Fri) 2003, 17:00.
'Global Warming Team' of COE presented.


Speakers：　　 Masao Minagawa (Laboratory of Geosphere Science)
　　　　　　　 　 Hisayuki Yoshikawa (Laboratory of Marine and Atmospheric Geochemistry)
　　　　　　　 　 Takeshi Nakatsuka (Laboratory of Polar Meteorology and Oceanography)

Chairperson ： 　Shinichiro Noriki (Laboratory of Marine and Atmospheric Geochemistry)



'Global Warming Team' is trying to solve the mechanisms of carbon cycle which is the most crucial component of Grobal Warming.. This time, they introduced 3 topics from their research plan.


1) Biogeochemical cycles of Tokachi river and fixation of carbon along the coast
　　[ Masao Minagawa ]

2) Study for CO2 exchange between the atmosphere and the ocean in the western North Pacific.
　　[ Yoshikawa Hisayuki ]

3) Biogeochemical cycle through river Amur to the Okhotsk Sea.
　　[ Takeshi Nakatsuka ]
