Principal investigator: Ichiro Yasuda (Professor, Atmosphere and Ocean Research Institute (AORI), The University of Tokyo, Physical Oceanography)
This team develop/introduce/make practical observational systems of vertical mixing and perform large-scale in-situ observations under corporations with other teams.
Principal investigator : Shuhei Masuda (JAMSTEC R&D Center for Global Change Group leader Physical Oceanography)
This team synthesises pre-existing ocean data with newly-acquired turbulence data using state-of-art assimilation technique. Our obsevation plans include ship-based hydrographic cruises in the Pacific and Indian oceans where a microstructure profiler will be used to measure turbulence strength in the ocean along the cruise track.
Principal investigator : Jun Nishioka (Hokkaido University⋅Institute of Low Temperature Science⋅Associate Professor⋅Chemical Oceanography)
This team performs research to understand the dynamics of nutrients (including N, P, Si and Fe) and their induced biological production in the western North Pacific. We plan to perform keen international collaborations from ocean observations to the data analyses.
Principal investigator : Xinyu Guo (Professor, Center for Marine Environmental Studies, Ehime University, Physical Oceanography)
This team performs reasearch to quantitatively evaluate energy dispersion in the ocean lateral boundary that partly contributes to the formation of western boundary currents such as the Kuroshio, and to understand the role of Kuroshio in supplying nutrients to primary production in the open ocean.
Principal investigator : Naomi Harada (JAMSTEC Research and Development Center for Global Change)
This team performs research lower-trophic level ecosystem structure/variability/dynamics and their relation to mixing in the western North Pacific where the most active biological drawdown of sea surface pCO2 area works in the world.
Principal investigator : Shin-ichi Ito (Professor, Atmosphere and Ocean Research Institute (AORI), The University of Tokyo)
This team performs research to elucidate direct and indirect influences of the long-term fluctuation of ocean mixing processes caused by 18.6-year nodal tide on fisheries resources by high resolution isotope analysis of fish juvenile otoliths and marine ecosystem-fish coupled models.
Principle investigator : Toshiyuki Hibiya (Professor, Graduate School of Science, The University of Tokyo)
This team performs research to formulate a “seamless” parameterization of diapycnal mixing processes that can be applied throughout the water column, namely, from the ocean surface down to the ocean bottom.
Principal investigator : Hiroyasu HASUMI (Professor, Atmosphere and Ocean Research Institute, The University of Tokyo, Ocean modeling)
This team performs research to reveal the three-dimensional structure of the North Pacific circulation induced by ocean mixing and to understand its influence on the climate, and also to describe the materials cycles in the North Pacific under the influences of physical transport and biogeochemical processes.
