ObjectivesBiogeochemistry of Trace Elements and Their Isotopes in the Pacific Ocean and the Antarctic Sea (GEOTRACES section GP-19)

The main purpose of this cruise is to establish the 2-dimensional meridional profiles of GEOTRACES trace elements and isotopes in the southern Pacific Ocean including the Antarctic Sea along the 170°W line, in order to advance ocean sciences on trace elements and isotopes as mentioned above. Little is known about the marine biogeochemical cycles on TEIs in the Pacific Ocean at the present stage. In the western Pacific Ocean, in particular, the northward Antarctic Bottom Water plays a key role in dynamic deepwater convection associated with active biogeochemical cycles. We conducted a similar cruise by R/V Hakuho Maru (KH-04-5) in the South Pacific Ocean in 2004-2005, and it should be of great interest to compare the data obtained this time with those in the past (10 years ago), revealing decadal changes in various physical, chemical and biological parameters in the western Pacific. Another important target of the cruise will be to study the submarine hydrothermal activity in the Mariana arc-backarc zone as a significant source of trace metals from lithosphere to seawater.
