Research Area

Indian Ocean, Antarctic Sea

Objectives

The KH-09-5 Cruise leg-1, -2, and -3 of R/V Hakuho Maru is planned to pursue Trace Element Oceanography in Japan as part of the international project SCOR-GEOTRACES (study of the marine biogeochemical cycles of trace elements and isotopes). The cruise aims at precise and detailed measurements of trace elements and isotopes in the Indian Ocean including the atmosphere and bottom sediment, in order to identify processes and fluxes that control the distribution of trace elements in water columns, and to elucidate their important linkage with the global climatic change. The cruise will collect seawater, air, plankton and sediment samples for the measurement of trace elements including the GEOTRACES key parameters, dissolved gases, stable- and radio-isotopes at ~20 locations chiefly along meridional lines (~65E and ~30E) in the western Indian Ocean and the Antarctic Sea.
