Sea ice biogeochemistry
Our laboratory is focusing on the bio-geo-chemical cycles in the ocean and their effects on the ocean environment. Target parameters are trace metals, organic and inorganic gasses in the ocean and sea ice. Research area is from Arctic, Okhotsk, Bering, Pacific, coast of Hokkaido to Southern Oceans. We welcome your joining as Master and Ph.D course students and JSPS postdoctoral fellow.
