1. Hydrographic casts and water sampling: measurements of vertical CTDO (Conductivity, temperature, depth and oxygen) profiles; measurements of dissolved oxygen, nutrients, chlorophyll, trace element concentrations and isotope compositions in seawater samples, using surface water sampler, NISKIN-X type water sampler.
2. In-situ filtration casts: trace element and isotope measurements of organic/inorganic particulate materials, using in-situ filtration/extraction pump system.
3. Multiple piston coring casts: trace element and isotope measurements in pore water and surface sediment.
4. Plankton casts: plankton sampling using Towing net.
5. Casts of optical sensors: measurement of photosynthetic parameters, optical radiance and irradiance.
6. ADCP (Acoustic Doppler Current Profiler) casts: vertical profiles of current velocity with a ship-mounted ADCP.
The chief scientist and the office for cruise coordination of the Atmosphere and Ocean Research Institute, the University of Tokyo will manage the execution of the project and the subsequent analysis of the data. Data obtained through the measurements of major chemical components, trace elements and various isotopes during the cruise, is expected to improve our understanding of past, present and future distributions of TEIs in the East Asian Marginal Sea, and also the relationships with important global processes of material circulations.
