| Objectives | The Japanese GEOTRACES cruise on board RV Hakuho-maru will sail from 30 June to 21 August 2022 along the GEOTRACES section cruise GP22 in the western North Pacific Ocean.
It is well known that both Oyashio and Kuroshio are strong surface currents and transport trace elements from marginal seas like the Sea of Okhotsk and the East China Sea to the western North Pacific. Moreover, atmospheric dust deposition from the Asian deserts supplies huge amounts of trace elements to the western North Pacific. However, this unique area has not been sufficiently covered by the meridional GEOTRACES section cruise. In this cruise, scientists are planning to occupy 17 stations and reveal the full-depth profiles of trace elements and their isotopes (TEIs) in the western North Pacific. In this cruise, they will also obtain bottom sediments with a multiple corer and a piston corer at some stations. |
