Objective
Change in material cycles and ecosystem by the climate change and its feed back ; Studies on the microbial-geochemical processes that regulate the operation of the biological pump in the subarctic and subtropical regions of the western North Pacific ; Effects of mesozooplankton on food web and vertical flux ; Study on development of new paleo-proxies ; Analysis of spatiotemporal distribution of net community productivity base on continuous measurements of dissolved oxygen/argon ratio ; Basic studies on effects of iron supply on seasonal variations of cryptophytes in the northwestern Pacific ; On-board continuous air-sea eddy flux measurement ; Development of drifting buoy system with in situ sea surface pCO2 sensor ; Identification of zooplankton species by fecal pellets ; Lidar observations of optical characteristics and vertical distribution of aerosols and clouds ; Anatomy of the ocean-atmosphere interface in mid-latitudes ; Variability of Salinity and Temperature in the North Western Pacific (Argo program) ; Archive of surface meteorological data ; Tectonic evolution of the Pacific Plate ; Standardising the marine geophysics data and its application to the ocean floor geodynamics studies ; Observational Research on the Kuroshio Transport and Sea Surface Flux ; Water sampling for making isotope distribution map over the Ocean ; Coccolithophore and Planktic foraminiferal ecology at NW Pacific
