Research Abstract

The investigation was carried out for exploring important processes for climate change in the polar ocean and atmosphere as well as atmosphere-ocean interactions and bio-geochemical systems. Under the global change, the key findings include the deteriorating carbon cycle associated with reduction both in marine ecosystem production and boreal forests. These results were reported at the international symposia of Hokkaido University in 2008 and 2009.
