Toward the understanding the response of marine ecosystems to the multiple environmental stressors

The subarctic region of the western North Pacific and the Arctic Ocean are one of the most serious area regarding the progress of the warming, ocean acidification, and hypoxia in the world. Focusing on the subarctic region of the western North Pacific and western Arctic Ocean, we would like to 1) understand the temporal changes in primary production and the biological pump, 2) understand the physiological response of marine phyto- and zooplankton to warming and ocean acidification that is occurring simultaneously with deoxygenation, and 3) develop a new model to understand the response of marine ecosystems and the biological pump to the environmental changes caused by multiple environmental stressors.
